Location of Quehanna Wild Area in Pennsylvania | |
Quehanna Wild Area (/kwəˈhænə/) is aprotected area within parts ofCameron,Clearfield andElk counties in theU.S. state ofPennsylvania; with a total area of 50,000 acres (78 sq mi; 202 km2), it covers parts ofElk andMoshannon State Forests. Founded in the 1950s as anuclear research center, Quehanna has a legacy ofradioactive andtoxic waste contamination, while also being the largeststate forest wild area in Pennsylvania, with herds ofelk. The wild area is bisected by the Quehanna Highway and is home tosecond growth forest with mixedhardwoods andevergreens. Quehanna has two state forest natural areas: the 1,215-acre (492 ha)M.K. Goddard/Wykoff Run Natural Area, and the 917-acre (371 ha)Marion Brooks Natural Area. The latter has the largest stand ofwhite birch in Pennsylvania and the eastern United States.
The land that became Quehanna Wild Area was home toNative Americans, including theSusquehannock andIroquois, before it was purchased by the United States in 1784. Settlers soonmoved into the region and, in the 19th and early 20th centuries, thelogging industry cut thevirgin forests;clearcutting and forest fires transformed the once verdant land into the "Pennsylvania Desert"[citation needed]. Pennsylvania bought this land for itsstate forests, and in the 1930s theCivilian Conservation Corps worked to improve them. In 1955 theCurtiss-Wright Corporation bought 80 square miles (210 km2) of state forest to focus on developing nuclear-poweredjet engines. They named their facility Quehanna for the nearbyWest Branch Susquehanna River, itself named for the Susquehannocks.
Curtiss-Wright left in 1960, after which a succession of tenants further contaminated the nuclear reactor facility and itshot cells withradioactive isotopes, includingstrontium-90 andcobalt-60. The manufacture of radiation-treated hardwood flooring continued until 2002. Pennsylvania reacquired the land in 1963 and 1967, and in 1965 established Quehanna as a wild area, albeit one with a nuclear facility and industrial complex. Thecleanup of the reactor and hot cells took over eight years and cost $30 million; the facility was demolished and its nuclear license terminated in 2009. Since 1992 the industrial complex has been home to Quehanna MotivationalBoot Camp, a minimum-security prison, which will close in 2026. Quehanna Wild Area has many sites where radioactive and toxic waste was buried, some of which have been cleaned up while others were dug up byblack bears andwhite-tailed deer.
In 1970 the name was officially changed to Quehanna Wild Area, and later that decade a portion of the 73.2-mile (117.8 km)Quehanna Trail was routed through the wild area. Primitivecamping by hikers is allowed, but the area has no permanent residents. Several other trails are open tocross-country skiing in the winter, but closed to vehicles. Quehanna is on theAllegheny Plateau and was struck by a tornado in 1985.Defoliating insects have further damaged the forests. Quehanna Wild Area was named anImportant Bird Area by the PennsylvaniaAudubon Society, and is home to many species of birds and animals.Eco-tourists come to see the birds and elk, and hunters come for the elk,coyote, and other game.
TheIroquoian-speakingSusquehannocks were the earliest recorded inhabitants of theWest Branch Susquehanna River basin, which includes Quehanna Wild Area. They were amatriarchal society that lived instockaded villages of largelong houses.[3] The Susquehannocks'numbers were greatly reduced by disease and warfare with theFive Nations of the Iroquois, and by 1675 they had died out, moved away, or beenassimilated into other tribes.[3][4] After this, the Iroquois exercised nominal control of the lands of the West Branch Susquehanna River valley. They also lived in long houses, primarily in what is nowNew York, and had a strongconfederacy which gave them power beyond their numbers. To fill the void left by the demise of the Susquehannocks, the Iroquois encouraged such displaced eastern tribes as theShawnee andLenape (or Delaware) to settle in the West Branch watershed.[3][4]
TheSeneca tribe of the Iroquois hunted in much of Pennsylvania and the Quehanna area.[5] The Iroquois and other tribes used theGreat Shamokin Path, the major native east–west path connecting the Susquehanna andAllegheny River basins, which passed south of what is now the wild area. The native village of Chinklacamoose (or Chingleclamouche) was on this path at the West Branch Susquehanna River, at what is nowClearfield to the southwest of Quehanna. TheSinnemahoning Path alongSinnemahoning Creek ran north of Quehanna; as the path with the gentlest grade, it may have been the route the firstPaleo-Indians took entering this part of Pennsylvania from the west.[6]
TheFrench and Indian War (1754–1763) and the subsequent colonial expansion encouraged the migration of many Native Americans westward to theOhio River basin. In October 1784, the United States acquired a large tract of land, including what is now Quehanna Wild Area, from the Iroquois in theSecond Treaty of Fort Stanwix; this acquisition is known as the Last Purchase, as it completed the series of purchases from the resident Native American tribes of lands within the boundaries of Pennsylvania, initiated byWilliam Penn and continued by his heirs.[3]
Although most of the Native Americans left this area of Pennsylvania, the state's Native American heritage can be found in many of its place names. The Susquehannocks were also known as the Susquehanna, from which theSusquehanna River and its West Branch obtained their names.[4] In the 1950s theCurtiss-Wright Corporation coined the name "Quehanna" for its nuclear reservation, which it derived from the last three syllables of "Susquehanna",[7] "in honor of the river that drained the entire region".[8] Part of Quehanna Wild Area lies in the Moshannon State Forest, named forMoshannon Creek, which means "moose stream" or "elk stream" in theLenape language.[9] Sinnemahoning Creek's name means "stonysalt lick" in Lenape.[10]
Prior to the arrival ofWilliam Penn and hisQuaker colonists in 1682, forests covered up to 90 percent of what is now Pennsylvania: more than 31,000 square miles (80,000 km2) ofeastern white pine,eastern hemlock, and a mix ofhardwoods.[11] Scull's 1770 map of theProvince of Pennsylvania showed the colonists' ignorance of the land north of the West Branch Susquehanna River; Sinnemahoning Creek was missing, and the region that includes Quehanna was labeled "Buffaloe Swamp".[12][13] This began to change when the land was purchased from the Iroquois in 1784, and became part ofNorthumberland County. In 1795 it became part ofLycoming County;[14][15] as the new county was divided into more townships, Quehanna became part of Chingleclamouche Township (named for the native village). Chingleclamouche Township was included inClearfield County when it was established in 1804. Later it was divided between at least three counties and many townships, and no longer exists under that name.[12]
The southern part of Quehanna Wild Area is now in parts ofCovington,Girard, andKarthaus townships in Clearfield County; they were incorporated in 1817, 1832, and 1841.[16] The northwest part of Quehanna is inBenezette Township inElk County, established in 1843.[17] The northeast part of Quehanna is inCameron County (incorporated in 1860) inGibson Township, which was formed in 1804 while part of Clearfield County.[18]
The firstEuropean American settlers arrived in Chingleclamouche Township in about 1793, and the first sawmill in Clearfield County began operating in 1805. Settlers initially occupied land along the river and creeks, as these provided a means of transportation. Some settlers would harvest timber and float it downstream once a year to make money for items they could not produce themselves, but by 1820 the first full-time lumbering operations began in the region. The white pine was the most sought after tree, yieldingspars for ships and timber for buildings. Hardwoods were also harvested, and eventually hemlocks were cut for their wood and their bark, which containedtannins used intanning leather.[19]

As lumber became an industry in Pennsylvania, the rivers and creeks were declared public highways by thePennsylvania General Assembly. This permitted their use to float logs to sawmills and markets.Log booms were placed on the West Branch Susquehanna River to catch the floating timber;Lock Haven built a boom in 1849, andWilliamsport'sSusquehanna Boom opened in 1851.[19][21] Businesses purchased vast tracts of land and builtsplash dams on the creeks; these dams controlled water in small streams that would otherwise be unable to carry logs and rafts. For example, in 1871 a single splash dam on theBennett Branch of Sinnemahoning Creek could release enough water to produce a wave 2 feet (0.6 m) high on themain stem for two hours.Mosquito Creek, which drains much of the southern part of Quehanna Wild Area, had at least nine splash dams in its watershed.[22] This was the predominant lumber transport system in the Quehanna region from 1865 to 1885 and after 1850, five different kinds of lumber rafts could be found on its streams and river.[19]
Much of the timber was too remote to be transported via the streams, andlogging railroads were the next development in the Quehanna lumber era. In or around 1880, these railroads allowed theclearcutting of the remaining forests. The Quehanna plateau was unusual in usingstandard gauge track for its logging railroads: most such railways werenarrow gauge. The logging railroads used specialgeared steam locomotives, such as theShay,Climax andHeisler.[23] Nine companies operated logging railroads in what became Moshannon State Forest; the Goodyear Lumber Company was the largest and cut much of what became Quehanna Wild Area between 1902 and 1912. The Central Pennsylvania Lumber Company logged land in the northern part of the wild area between 1907 and 1911.[20]

There were only two major roads on the Quehanna plateau in the 19th and early 20th centuries, both originallyturnpikes. The Caledonia Pike ran east–west fromBellefonte toSmethport, and passed south of what became the wild area, while the Driftwood Pike ran from near Karthaus north toDriftwood on the Sinnemahoning, and passed through the wild area.[24]Wagon trains and railroads brought supplies to the lumber camps in the woods; somewood hicks set up small farms on cleared land that also provided food.[23] There were at least eight farms in Quehanna, though they were not very productive because of "poorly drained acid soil and a short growing season".[23]
The lumber era in Quehanna did not last; theold-growth andsecond-growth forests were clearcut by the early 20th century. Fire had always been a hazard; the sparks from logging steam engines started manywildfires, and more wood may have been lost to fires than to logging in some areas. On the clearcut land nothing remained except the discarded, dried-out tree tops, which were very flammable; much of the land burned and was left barren. The soil was depleted of nutrients, fires baked the ground hard, and jungles of blueberries, blackberries, and mountain laurel covered the clearcut land, which became known as the "Pennsylvania Desert".[11][23][25]

As the timber was exhausted and the land burned, many companies abandoned their holdings.[25] Conservationists such asJoseph Rothrock became concerned that the forests would not regrow without proper management. They called for a change in the philosophy of forest management and for the state to purchase land from the lumber companies. In 1895, Rothrock was appointed the first forestry commissioner in what became the Pennsylvania Department of Forests and Waters, the forerunner of today'sDepartment of Conservation and Natural Resources (DCNR). In 1897, the Pennsylvania General Assembly passed legislation that authorized the purchase of "unseated lands for forest reservations", and the first of thePennsylvania state forest lands were acquired the following year.[26][27]
The state first bought land that became the Moshannon State Forest in 1898; the second purchase, and first in the Quehanna region, was 3,263 acres (1,320 ha) in the Three Runs area, acquired for $1 an acre ($2.47 a hectare) in 1900. Three smaller state forests (Karthaus, Sinnemahoning, and Moshannon) were merged to form the present Moshannon State Forest; in 1997, the forest covered 131,622 acres (53,266 ha). The first purchase for the Elk State Forest was made in 1900, and by 1997 it encompassed 197,729 acres (80,018 ha). Forty-six percent, or 22,179 acres (8,976 ha), of the total 48,186 acres (19,500 ha) of Quehanna Wild Area lies in the Elk State Forest. The remainder lies in the Moshannon State Forest.[1][28]
The state established a tree nursery in the Moshannon State Forest in 1911, which became the largest in Pennsylvania before it closed in 1980.[28] In addition to planting millions of trees, in 1913 the state encouraged use of state forest lands by allowing permanent leases for camp sites; when the state stopped issuing new permits in 1970, 4,500 campsites had been leased.[28] ThePennsylvania Game Commission began purchasing land for stategame preserves in 1920,[29] and by 1941, State Game Lands 34, which is partly in Quehanna Wild Area, had been established.[30] Despite these conservation efforts, major forest fires swept the Moshannon and Elk state forests in 1912, 1913, 1926, and 1930, and minor fires occurred in other years.[28]

During theGreat Depression, theCivilian Conservation Corps (CCC) established ten camps in Moshannon State Forest, and ten in Elk State Forest. The young men of the CCC planted trees, blazed new trails, built roads and bridges, and fought fires, which continued to be a problem. In 1938 a fast-moving fire in the Elk State Forest, north of Quehanna, killed eight firefighters. The CCC also built structures and established or improved many of thestate parks, includingParker Dam andS. B. Elliott State Parks on the western Quehanna plateau. The United States' entry into World War II ended the CCC, and all its camps were closed by the summer of 1942. TheQuehanna Trail passes near or through the sites of several former CCC camps.[28][31][32]
Other Depression-era public works projects shaped the area. TheWorks Progress Administration (WPA) had at least two camps for World War I veterans in the Quehanna area, and built the Karthaus emergency landing field forairmail planes, similar to those that becameMid-State Regional Airport andCherry Springs Airport. The3,700-by-1,800-foot (1,100 by 550 m) airfield was built in 1935 and 1936 along Hoover Road (the old Driftwood Pike), just north of what is now M.K. Goddard/Wykoff Run Natural Area. During World War II, the landing strip was blocked to prevent enemy planes from secretly landing there.[33][34]
In 1946 the Mosquito Creek Sportsmen's Association was founded to promote conservation in the region. One of the association's initial concerns was the acidification of streams, which they originally attributed totannic acid from the trees used by the beavers to construct theirdams. With the assistance of Pennsylvania's Department of Forests and Waters, Game Commission, andFish and Boat Commission, they dynamited 79 dams. Afterward, they discovered the water was acidic upstream of the dams too, and eventually realized that the problem was caused byacid rain, not the beavers. The association has operated several stations to reduce the acidity of Mosquito Creek and its tributaries, with technical assistance from thePennsylvania State University (Penn State).[35][36]

In a December 8, 1953 speech to theUnited Nations, PresidentDwight D. Eisenhower announced a newAtoms for Peace policy, andCongress enacted his program into law the following year.[8] Atoms for Peace "made funding accessible to anyone who had the imagination, if not the ability, to harness the atom's power for peaceful purposes".[37] Under the new program, the airplane manufacturerCurtiss-Wright Corporation sought a large isolated area in central Pennsylvania "for the development of nuclear-poweredjet engines and to conduct research innucleonics,metallurgy,ultrasonics,electronics, chemicals and plastics".[38][39] Curtiss-Wright worked closely with the state, and in June 1955,GovernorGeorge M. Leader signed legislation that authorized the construction of a research facility at Quehanna. TheCommonwealth of Pennsylvania sold Curtiss-Wright 8,597 acres (3,479 ha) for $181,250 ($22.50 an acre, $55.60 a hectare), and gave the company a 99-year lease on the remaining 42,596 acres (17,238 ha) at $30,000 a year. Curtiss-Wright controlled 51,193 acres (80.0 sq mi; 207.2 km2) in a regular 16-sided polygon, which was easier to fence than a circular area.[8][37][40][41]
The state constructed $1.6 million of roads to the area; the Quehanna Highway was built on parts of an old CCC road, which followed an earlier logging railroad grade. Pennsylvania also canceled 212 camp site leases to help ensure security for the installation. Curtiss-Wright built three facilities on its land. The first was a nuclear research center with anuclear reactor and sixshieldedradiationcontainment chambers for handling radioactive isotopes, referred to ashot cells, at the end of Reactor Road. The second was for jet engine trials, and had two test cells with bunkers just north of Quehanna Highway, about 0.5 miles (0.8 km) apart. The northern test cell was at the center of the 16-sided polygon; even if a jet engine broke its moorings, it could not leave the polygonal area. Both of these were on the land which Curtiss-Wright had purchased, which was a regularoctagon surrounded with a 24-mile (39 km) fence built by forest rangers, supervised from three guard houses on Quehanna Highway and Wykoff Run Road. The third installation was an industrial complex at the southeast edge of the polygon, in Karthaus Township, on the Quehanna Highway. At this site, a Curtiss-Wright division manufactured Curon foam for furniture and household products and usedberyllium oxide to make high-temperatureceramics for application in the nuclear industry.[8][37][40][41][42]

In 1956 Curtiss-Wright began isotope work at the facility,[38] andThe New York Times published two stories on the new nuclear research laboratory that year, followed by a November 1957 report that the one-megawatt nuclear reactor was completed.[43][44][45] In 1958, the corporation received a twenty-year license from theAtomic Energy Commission (AEC) to operate a four-megawattopen pool nuclear research reactor, and received permission from the Pennsylvania Sanitary Water Board to dispose of someradioactive waste in Meeker Run, atributary of Mosquito Creek.[8] The project was billed as "the greatest thing that ever happened in North Central Pennsylvania", and was expected to employ between 7,000 and 8,000 people.[40] Curtiss-Wright spent $30 million on the project, and developed a community for its scientific and technical staff at the village ofPine Glen, southeast of Karthaus in Centre County.[8]
By 1960 theAir Force had decided not to pursue nuclear-powered aircraft, and the federal government canceled $70 million in "high-altitude testing contracts" with Curtiss-Wright.[8][40] By June 1960, the reactor was on standby and only 750 employees remained, 400 of whom were in the Curon foam division; many engineers and scientists had already left.[40] On August 20, 1960, Curtiss-Wright announced that it was donating the reactor facility to Penn State and selling its Curon foam division; the remaining 235 employees lost their jobs.[46] Penn State, located about an hour south of Quehanna, had itsown nuclear reactor, but intended to use the Quehanna facility for research and training.[38]
The Curtis-Wright reactor was dismantled and its fuel returned to the AEC. Martin Company, which soon becameMartin Marietta, leased the hot cells, intending to use them in the manufacture of smallradioisotope thermoelectric generators. Curtiss-Wright warned Penn State "that the radiation involved in Martin's operations would be 'extremely high' and of a type that posed a particular risk to human health",[8] but Curtiss-Wright itself had left both solid and liquid radioactive waste in the facility. Some of the Curtiss-Wright waste was contaminated with toxic beryllium oxide. Penn State had acquired the reactor license, and with it came legal responsibility for the nuclear waste on the site; its plan with the AEC called for the release of 90 percent of the liquid radioactive waste into the environment and the burial of most radioactive solids on site. Items coated with beryllium oxide dust "were covered in plastic and buried out in the woods", where some were unearthed by black bears andwhite-tailed deer.[8][38][47] Once jet engine testing stopped, the bunkers at the test cells were used "to store hazardous and explosive material".[48]

In 1962 Martin Marietta began to manufactureSystems for Nuclear Auxiliary Power (SNAP) thermoelectric generators under a contract with the AEC; their AEC license allowed them to have up to 6 millioncuries of radioactivestrontium-90 in the form ofstrontium titanate, which powered the SNAP generators. A SNAP-7 reactor made at Quehanna was used in the world's first nuclear-powered lighthouse, theBaltimore Harbor Light, from May 1964 to April 1966.[8][38] In early 1963, Curtiss-Wright still owned or leased all of Quehanna and sublet land along Quehanna Highway to a firm that recoveredcopper from wire by burning off its insulation, a procedure that contaminated the soil. On July 12, 1963, GovernorWilliam Scranton announced the termination of Curtiss-Wright's lease on 42,596 acres (17,238 ha); the state paid the company for the roads it had built, and Curtiss-Wright donated six of the eight buildings in the industrial complex to the state.[49] In 1965 the state legislature passed an act declaring the former leased area awilderness area,[28][49] andMaurice K. Goddard, secretary of the Department of Forests and Waters, named it the Quehanna Wilderness Area.[50]
Although Martin Marietta completed its AEC contract and its lease expired on December 21, 1966, it had to stay at the reactor site "until radiation contamination was brought to acceptable levels".[49] Martin Marietta partially decontaminated the site, and in April 1967 undertook a joint radiological survey with Penn State and the AEC. The survey found "licensable [sic] quantities of strontium-90 stayed behind as structural contamination and residual radioactivity in piping and tanks, estimated at about 0.2 curies".[38] This met the standards for that day, although Penn State did raise questions about the contamination remaining.[38]Strontium is chemically very similar tocalcium (both arealkaline earth metals) and can be absorbed by the body, where it is chiefly incorporated into bones. Strontium-90 decays bybeta decay and has ahalf-life of 29 years; when it is in the body, its radioactivity can lead tobone cancer andleukemia.[51]
Many in the conservation movement urged the state to buy back the land, especially after the Curtiss-Wright lease was canceled. In April 1967 Penn State vacated the site and gave the reactor complex to the state. Martin Marietta departed in June 1967, and early in that same year, Pennsylvania bought the remaining land back from Curtiss-Wright for $992,500, about $811,000 more than they had sold it for in 1955. Various usage plans for the area were proposed, including: a vacation resort with a large artificial lake, motels,golf courses, andhoneymoon resort; a Penn State game preserve stocked with exotic animals likebison andboar; a large youth camp for several hundred children; and a radioactive waste disposal site. By November 1967, all of the land was back in the state forests and state game lands.[38][42][49]
In 1967, Pennsylvania leased the reactor complex to theNuclear Materials and Equipment Corporation (NUMEC), which already had a federal license to work with nuclear materials. NUMEC, which soon became a subsidiary ofAtlantic-Richfield Corporation (ARCO), set up a large irradiator in what had been the reactor pool. The irradiator contained over 1 million curies ofcobalt-60 to produce intensegamma rays, which were used to sterilize medical equipment and irradiate food and wood. In the spring of 1967 the state had concluded that radiation contamination at the Quehanna site "could never be completely cleaned up", and so was glad to find a tenant with nuclear experience.[8][38]

A group of NUMEC employees discovered that irradiating hardwood treated with plastics produced very durable flooring. In 1978 they formed PermaGrain Products, Inc. as a separate company from ARCO, and purchased the rights to the process as well as "the main irradiator, a smaller shielded irradiator and related equipment".[38] PermaGrain sold the flooring for use inbasketball courts and gymnasiums, and was the longest occupant of the Quehanna facility, operating there from 1978 to December 2002. PermaGrain also let Neutron Products, Inc., a Maryland company, do cobalt-60 work in its hot cells, which required an amendment of their license from theNuclear Regulatory Commission (NRC, the successor to the AEC).[8][38][52]
In 1993, strontium-90 contamination in the reactor facility led the NRC to require PermaGrain to begin decontamination work, and the Pennsylvania DEP commissioned a "site characterization study".[38] In 1998, a firm named NES began the cleanup work; they changed their name to Scientech in 1999 and toEnergySolutions in 2006. The cleanup was originally estimated to take six months; by 2006 it had taken 8 years and cost $30 million. According to thePennsylvania Department of Environmental Protection's (DEP) Bureau of Radiation Protection: "Inadequate characterization of the site and the presence of ongoing industrial operations resulted in many project delays and increased costs."[38] The hot cells proved to have more radioactive sources than originally thought. In October 1998 a Scientech worker doing decontamination cut a tube in hot cell number 4, which accidentally released strontium-90 into PermaGrain's work area. As a result, a robot had to be constructed to remove 3,000 curies of cobalt-60 in two of the hot cells, dismantle cell 4, and decontaminate the rest remotely.[38]

After the accidental release, another radiological survey was performed, and the state government concluded that PermaGrain needed to be relocated. The DCNR made the policy decision that Quehanna Wild Area would be closed to industrial uses. After looking at multiple sites with Clearfield County development authorities, a new site for PermaGrain Products was purchased, and the company submitted its plans for a new building and license to the NRC in October 2001. In order to approve the move to the new site, the NRC required PermaGrain to provide an inventory of all their cobalt-60 sources, dispose of a damaged source, and dispose of any other sources not mechanically certified. However in late December 2002, PermaGrain filed for bankruptcy underChapter Seven.[38] PermaGrain had employed 135 people in 1988 and 80 in 1995.[42]
When PermaGrain went bankrupt, about 100,000 curies of cobalt-60 were abandoned at the reactor facility, which was now under the control of Pennsylvania's government. The DEP assumed responsibility for the NRC license and legacy contamination. TheUnited States Environmental Protection Agency (EPA), working with the NRC and state, removed the cobalt-60 from the site for disposal at thelow-level radioactive waste facility inBarnwell, South Carolina in September 2003. Scientech continued decontamination work and demolished the hot cells; much of this work was done robotically, with financial aid from theDepartment of Energy.[38][53]
The cleanup was thought finished, so a final survey was done in December 2004, and a Final Status Survey Report was filed in February 2005. However, when the NRC and scientists from theOak Ridge Institute for Science and Education surveyed the facility in May 2005, they found many areas of contamination above the legal limits. According to the NRC's Quehanna Site Status Summary, strontium-90 had contaminated the "buildings as well as ... surface and subsurface soil" but was not in groundwater.[53] More cleanup work was done in the summer of 2005, but the site still did not meet NRC regulations. DEP concluded that "some type of migration of radioactive material [was] taking place in the concrete at the facility",[53] and changed its disposal plan. The new plan called for demolition of the building without completing decontamination, and disposal of the above ground material in a regularlandfill. This plan was approved by the NRC in October 2006, and a December 2006 survey showed "that the above grade structure met the release limits" of the disposal plan.[38][53][54] The former reactor structure was demolished, and on May 13, 2009 the NRC released the state from its license for the site. As of 2011, a small octagonal "restricted area" around the reactor site is still shown on official DCNR maps.[55]

On September 20, 1967, two Bureau of Forestry employees attempted to remove a metal ladder from a 20,000-US-gallon (76,000 L; 17,000 imp gal) metalstorage tank forjet fuel at the northern jet engine test cell. Both were killed in an explosion when theacetylene torch cut through the tank wall and ignited fumes inside it. A tract within the Elk State Forest at the northern edge of the wild area is known as Noble-Chambers Memorial Forest in their memory.[28][56][57] Although Fergus reports entering a bunker in his 2002 book,[7] and Young describes a bunker's slit windows in his 2008 book,[48] as of 2010 the southern bunker was covered with earth, and the northern bunker is still completely intact and can be entered.
In 1986, former Curtiss-Wright and Martin Marietta employees testified about hazards and waste disposal practices before a hearing of thePennsylvania House of Representatives. A former employee told how a night watchman walked through a spill in the reactor complex without knowing it; the man's car and the carpets in his house had to be destroyed as a result of the contamination. Others told about burying hundreds of drums of unknown waste from the reactor facility and digging a trench 125 by 25 feet (38.1 by 7.6 m) and 12 feet (3.7 m) deep for waste drums north of Wykoff Run Road. The locations of some sites, which included radioactive waste, beryllium oxide, and other toxic compounds, were not recorded. A forest ranger testified that he had dismantled a CCC-built drinking water fountain fed by aspring because it was downhill from the reactor and he feared people might drink contaminated water from it.[8][42][58]
In 1964, drilling revealed that the Quehanna Wild Area's geology andhydrology made it unsuitable for burying waste. However, according to Seeley'sGreat Buffaloe Swamp, a history of the Quehanna region, there are 180 contamination sites in the wild area.[42] Waste has been found at the former air field, within the M.K. Goddard/Wykoff Run Natural Area, near the industrial complex, at the former Lincoln Farm, and at the copper wire-burning site on the highway. These last three waste sites were cleaned in 1991 at a cost of $187,698. At the wire-burning site 150 short tons (140 t) of contaminated soil were removed from 3 acres (1.2 ha), with clean earth and grass seed placed on top of the area. The waste was also removed from the farm site, but at the industrial complex the waste was covered with 2,500 cubic yards (1,900 m3) of soil on 4 acres (1.6 ha) and fenced off.[42][59]

The industrial complex covers about 100 acres (40 ha) on both sides of Quehanna Highway at the southeast edge of the Quehanna Wild Area. Although the industrial complex lies within the historic 16-sided polygon, it is no longer part of the wild area.[55] After Curtiss-Wright's lease ended and it donated six of the eight buildings in the complex to the state in 1963, Pennsylvania formed the Commonwealth Industrial Research Corporation to administer and lease the Quehanna facilities, which it did until 1967.[49] Over the years a series of tenants have occupied parts of the industrial complex. One company manufactured loggingtrailers there from 1967 to 1971, and another processed frozen meat from 1968 to 1970. In 1968Piper Aircraft established a plant to make metal and plastic parts for airplanes. The complex was renamed from Quehanna to Piper, a name it retains. Piper employed up to 1,000 people, but moved its operations from Pennsylvania to Florida in 1984.[28][42][60]
The Young Adult Conservation Corps was also based at Piper from 1977 to 1982. This federally funded program employed up to 45 young people for local conservation projects in the state parks and forests and on state game lands. In addition,Sylvania Electric Products used two buildings in the industrial complex as warehouses for light bulbs until 1993. In 1992, thePennsylvania Department of Transportation began aheavy equipment training school at Piper, which is still in operation.[28][60]
In 1992 thePennsylvania Department of Corrections opened the Quehanna MotivationalBoot Camp at Piper as the state's "first military-style motivational boot camp".[61] Theminimum security program for non-violent, first-time offenders has accepted both male and female inmates from the start. Originally designed to house 200, the Department of Corrections expanded the facility in the late 1990s to a capacity of 500 on about 50 acres (20 ha). The inmates spend six months in a military-style program that offers opportunities for education and builds positive life skills; they also are offered drug and alcohol therapy. Those who successfully complete the boot camp program, which is considered an alternative to prison, are released onparole.[28][49][61] The boot camp began to receive men and women from the "general population of state prison inmates" in 2005 and 2006, respectively.[62] At the end of June 2009, the facility had 494 inmates, 61 percent of whom were in the boot camp program, and cost just over $17 million a year to operate.[62] In January 2026 it was announced the facility will close by March 1, 2026. Future plans for the property are indeterminate.[63]

In December 1970 the state forest commission officially changed the designation from Quehanna Wilderness Area to Quehanna Wild Area, making it the firststate forest wild area in Pennsylvania.[64][65] Elk and Moshannon state forests jointly administer Quehanna's 48,186 acres (75.3 sq mi; 195.0 km2); for comparison, this is over three times larger than the 23-square-mile (60 km2) area ofManhattan,[66] making Quehanna the largest of the 16 wild areas in the state. According to the Pennsylvania Bureau of Forestry, "a wild area is an extensive area, which the general public will be permitted to see, use and enjoy for such activities as hiking, hunting, and fishing. No development of a permanent nature will be permitted in order to retain the undeveloped character of the area. These areas will be administered according to the principals of forest protection...".[64]
Consequently, within a wild area, no new permanent camp leases, mines, wells, roads, orrights-of-way for utility lines are allowed, although existing camps, roads, and rights-of-way may remain. Vehicles are allowed only on public roads; trails are limited to hikers, bicyclists, equestrians, and wheelchairs, and only primitive camping by backpackers is allowed.[64] Quehanna has two paved roads open to vehicles, and is crossed by rights-of-way for threeelectrical power lines and twonatural gas pipelines.[55] It is one of the largest areas in Pennsylvania without permanent inhabitants.[37]

The state forest system also has natural areas, with more restricted usage. According to the Bureau of Forestry, "A natural area is an area of unique scenic, historic, geologic or ecological value that will be maintained in a natural condition by allowing physical and biological processes to operate, usually without direct human intervention."[64] Quehanna Wild Area contains two state forest natural areas: the 1,215-acre (492 ha)M.K. Goddard/Wykoff Run Natural Area in the center,[67] and the 917-acre (371 ha)Marion Brooks Natural Area on the northwest edge.[68] Marion Brooks Natural Area, known for its 22-acre (8.9 ha) stand ofwhite birch, was formerly known as Paige Run Natural Area; in 1975 it was renamed for Marion E. Brooks, a pioneering environmentalist from Elk County.[7][28][69] Quehanna Wild Area also has two wildlife viewing areas withblinds for observing elk and other animals: Beaver Run Dam's pond and wetlands and Hoover Farm's fields and feeding plots.[68]
The Quehanna plateau is home to theQuehanna Trail, a 73.2-mile (117.8 km) loophiking trail, about 34 miles (55 km) of which are in Quehanna Wild Area. The trail was built in 1976 and 1977 with help from a federally funded jobs program, the Young Adult Conservation Corps, and the Pennsylvania Conservation Corps. Parts of the trail have been moved, away from damage caused by the 1985 tornado, to avoid pipelines, to circumvent the Piper Boot Camp, and to pass closer to streams.[70][71] The wild area also has six shallow ponds forwaterfowl and other wildlife, the result of dams built on marshy areas in the 1970s.[72] In 1997 the whole Quehanna Wild Area was declared PennsylvaniaImportant Bird Area #31 by the PennsylvaniaAudubon Society.[73][74] In 2003, the Bureau of Forestry proposed expanding the Quehanna Wild Area by incorporating more of the surrounding Elk and Moshannon State Forests.[75]
Despite efforts to restrict use, some environmentalists criticize Quehanna's administration. Christopher Klyza, author ofWilderness Comes Home: Rewilding the Northeast, notes that the Pennsylvania wild areas are not truewilderness areas. He is especially critical of the continued use of roads through the wild areas and limited logging allowed "for forest health and wildlife habitat improvements".[76]

Quehanna Wild Area lies at an elevation of 1,896 feet (578 m) on theAllegheny Plateau.[2] The area falls into portions of two distinct geologicalphysiographic provinces, with all but the northernmost part in thePittsburgh Low Plateau, known for its coal and mineral deposits, and characterized by steep-cut stream beds. The northernmost part of the wild area, including Marion Brooks Natural Area, is in theDeep Valleys section, home to some of the most remote and wild areas of the state; streams here have cut deep valleys with steep-sided slopes.[79][80][81] In the southern part of Quehanna Wild Area, the Mosquito Creek gorge is up to 500 feet (150 m) deep, and the Red Run gorge in the north is almost 900 feet (270 m) deep.[82]
The Allegheny Plateau formed in theAlleghenian orogeny some 300 million years ago, when the part ofGondwana that became Africa collided with the landmass that became North America, formingPangaea. In thedissected plateau, years oferosion have cut away the soft rocks, forming the valleys, and leaving the hardest rocks relatively untouched. The land on which Quehanna Wild Area sits was part of the coastline of a shallow sea that covered a great portion of what is now North America in thePennsylvanian subperiod. The high mountains to the east of the sea gradually eroded, causing a buildup ofsediment made up primarily ofclay,sand andgravel. Tremendous pressure on the sediment caused the formation of the rocks that are found today.[83][84]
At least five major rock formations from theDevonian andCarboniferous periods are present in Quehanna Wild Area. The youngest of these, which forms the highest points on the plateau, is the PennsylvanianAllegheny Formation, which has clay, coal, limestone, sandstone, and shale. Below this is the PennsylvanianPottsville Formation, a gray conglomerate that may contain sandstone,siltstone, and shale, as well asanthracite coal, and which forms much of the Quehanna plateau. The next formations are found in the valleys and gorges which the creeks have eroded over time. The first of these is theMississippianPocono Formation, which is buff-colored with shale, coal, and conglomerate inclusions; parts of this formation are also known as the Burgoon Sandstone. Below this is the lateDevonian and early MississippianHuntley Mountain Formation, which is made of relatively soft grayish-red shale and olive-gray sandstone. The lowest and oldest layer is the red shale and siltstone of theCatskill Formation.[77][85][86][87][88]
The Allegheny Plateau has acontinental climate, with occasional severe low temperatures in winter and average dailytemperature ranges (the difference between the daily high and low) of 20 °F (11 °C) in winter and 26 °F (14 °C) in summer.[89] Quehanna Wild Area is part of the Mosquito Creek and Wykoff Run watersheds, where the mean annualprecipitation is 40 to 42 inches (1,016 to 1,067 mm).[90] Weather records are not available for Quehanna Wild Area, but they are known for the nearby village of Karthaus. The highest recorded temperature at Karthaus was 106 °F (41 °C) in 2011, and the record low was −22 °F (−30 °C) in 1994. On average, January is the coldest month, July is the hottest month, and June is the wettest month.[91]

On May 31, 1985, an outbreak of 43 tornadoes struck northeasternOhio, western and central Pennsylvania,New York, and southernOntario, killing 88 people. The Storm Data Center of theNational Weather Service rated the outbreak "the 12th most 'significant' tornado event of all time".[92] Pennsylvania was struck by 17 tornadoes thatMemorial Day, including the onlyF5 tornado on theFujita scale in the state's history. The tornadoes caused 65 deaths in Pennsylvania and were not dissipated by the state's mountainous landscape, "forever putting to rest the myth that such terrain can deter them".[92]
An F4 tornado passed through Quehanna Wild Area; its path of destruction crossed the Quehanna Highway at the Clearfield–Cameron county line.[41][93] It traveled over 69 miles (111 km) of mainly dense forest and wilderness in central Pennsylvania, and damaged or destroyed buildings early in its life, including a CCC-built lodge at Parker Dam State Park. The damage path from this storm was estimated to be at least 2.2 miles (3.5 km) wide.[93][94] Its winds—200 to 260 miles per hour (320 to 420 km/h)—ripped up small and medium-sized trees and shrubs, tore leaves and limbs from some of the big trees, and snapped others like matchsticks. As it headed west through Moshannon State Forest in Clearfield and Centre counties,Gregory S. Forbes, then a meteorology professor at Penn State, said the debris from the tornado was visible on hisWSR-57 radar scanners.[92][93] The reactor building was just north of the tornado's path and suffered $200,000 in damage, but no radiation leaks occurred.[94]
The tornado outbreak injured more than 1,000 people and caused $450 million in total damages and destruction. Moshannon State Forest lost an estimated $8 million in lumber to the tornado that hit Quehanna; after the storm, $2 million in timber was salvaged in the state forest.[95] In the ensuing years, the affected forest at Quehanna, though younger and smaller than the surrounding woods, has partly recovered. The official map for the Quehanna Trail is labeled "tornado zone" where the twister passed through the wild area.[41][96]

Thevirgin forests of what became Quehanna Wild Area were different in composition and quality than those of today. Eastern white pine and eastern hemlock were more common, often found on shady slopes and damp areas on plateaus.Chestnut oak andpitch pine favored slopes that were sandy or rocky, and the forest had a mixture of hardwoods, includingash,beech,birch,chestnut,maple, andyellow poplar. Eachacre (0.4 ha) of these virgin forests could produce up to 100,000board feet (236 m3) of white pine and 200,000 board feet (472 m3) of hemlock and hardwoods. For comparison, the same area of forest today produces a total of 5,000 board feet (11.8 m3) on average.[25][28] The virgin forests cooled the land and streams. Centuries of accumulated organic matter in the forest soil caused slow percolation of rainfall into the streams, so they flowed more evenly year-round.[97]

The clearcutting and repeated fires changed all of this. New growth was often composed of different plants and trees than had originally been there. Near Beaver Run in Quehanna there are wetlands that were originally hemlock forest. Hemlockstranspire large amounts of water and once they were gone the soil was too wet to support most trees; thebracken andferns that replaced the hemlocks altered the soil qualities to discourage trees as well.[98] Within the Quehanna Wild Area 650 acres (260 ha) arewetlands.[99] Fires and erosion removed nutrients from the soil, and in some areas the soil was so poor in nutrients that only white birch, apioneer species, would grow there. Marion Brooks Natural Area has the largest stand of white birch in Pennsylvania and the eastern United States. These trees are now 80 to 90 years old and reaching the end of their lifespans.[68]
Besides forest fires and tornado damage, there have been other threats to Quehanna's forests in the 20th century. Many trees were lost whenchestnut blight wiped out theAmerican chestnut trees by 1925; in the Quehanna area, this species constituted between one-quarter and one-half of the hardwoods. In the 1960s,white and chestnut oak trees had high mortality from pit scale insects and associated fungi.Larvae ofoak leaf roller moths, whichdefoliate oaks, first appeared on 8,200 acres (3,300 ha) of Quehanna Wild Area in the late 1960s; at their peak in the late 1960s and early 1970s they had defoliated 234,700 acres (95,000 ha) of Moshannon State Forest and 110,000 acres (45,000 ha) in Elk State Forest, with moderate to heavy tree mortality. A similar pest,oak leaf tier, stripped 375,000 acres (152,000 ha) of oaks in Elk State Forest by 1970. Thegypsy moth defoliated over 156,000 acres (63,000 ha) of deciduous trees in the 1970s and 1980s.[28] The forests within the Quehanna Important Bird Area are 84 percent hardwoods, 4 percent mixed hardwood and evergreens, less than 1 percent evergreens, 7 percent transitional between forests and fields, and 3 percent perennial herbaceous plants.[99] As well as trees, the forests haveblueberry andhuckleberry bushes and thickets ofmountain laurel andrhododendron.[7]
Some animals, previously present in abundance, have disappeared, or the populations declined, through habitat loss. By 1912, after the forests had been clearcut, Quehanna was covered by "vast expanses of brush, created when the root systems of cut-off trees sprouted up through the discarded tops and limbs of the logged forest".[7] Once the forest fires were controlled, thisbrush offered habitat for many game species. By the early 1940s, the CCC had thinned brush in many areas, and the forest had matured. Shade from thecanopy decreased brush in theunderstory. By the early 21st century, many of the trees in Quehanna were 80 to 100 years old, and the maturation of the forests led to the disappearance of species likebobwhite quail,ring-necked pheasant, andsnowshoe hare; white-tailed deer,ruffed grouse,black squirrel, andcottontail rabbit all became less common. Efforts by the Mosquito Creek Sportsmen's Association to reintroduce bobwhite quail, ring-necked pheasant, and snowshoe hare have been unsuccessful.[100][101]
Other animals becamelocally extinct through overhunting. The last elk in Pennsylvania was killed in Elk County in 1867. The Pennsylvania Game Commission brought 177 animals from theRocky Mountains to the state from 1913 to 1926; today the elk herd of over 600 animals can often be seen in Quehanna Wild Area.[68] Between 1906 and 1925, Pennsylvania became so concerned about declining numbers of white-tailed deer that it imported nearly 1,200 animals fromMichigan to re-establish the species, and made it the official state animal in 1959.[102] In the early 21st century, over-grazing by deer threatens plant diversity.[73] By the early 20th century, thefisher, a small mammal similar to theEuropean polecat orAmerican marten, was hunted to extinction in Pennsylvania. Between 1994 and 1998, 190 animals were released in five sites in the northern part of the state, including 23 animals along Quehanna's Wykoff Run in 1995. Breeding populations of fisher appear to have been reestablished.[103]

Still other animals seem to thrive regardless of the maturity of the forest or the presence of the understory. Common animals found in Quehanna includechipmunks,porcupine, andbeaver, omnivores such as theblack bear andraccoon, and predators likebobcat,red fox, andcoyote (which has been in Pennsylvania since the 1930s). Many of the streams in Quehanna Wild Area are known fortrout (brook, brown and rainbow); some populations are wild and others arestocked by thePennsylvania Fish and Boat Commission and Mosquito Creek Sportsmen's Association. The wild area is also home totimber rattlesnake,eastern garter snake, andspring peeper (a type of frog), as well as butterflies likegreat spangled fritillary,monarch,red-spotted purple, andblack,eastern tiger, andspicebush swallowtails. Any of these mammals, especially the white-tailed deer, can carryticks, and such tick-borne diseases asLyme disease are a health concern for hikers.[68][101][104][105][106]
As an International Bird Area, Quehanna's forests are recognized as a "large, unfragmented tract with exceptional diversity of woodland species" and are home to 102 species of birds.[73][99] Common birds includeAmerican crow,black-capped chickadee,blue jay,broad-winged hawk,common raven,hermit thrush,house sparrow,northern waterthrush,starling,whip-poor-will, andwild turkey. Quehanna Wild Area includes a variety of forest,riparian, and wetland habitats that support a diversity of animals. The shrub and scrubland areas left by the 1985 tornado and cleared for elk to feed in are home toindigo bunting andprairie warbler, while ponds and wetlands attract waterfowl such ashooded merganser andwood duck, and wading birds likegreat blue heron. The birch forest of Marion Brooks Natural Area is home todowny,hairy, andpileated woodpeckers, the oak forest of M.K. Goddard/Wykoff Run Natural Area hasblack-throated green warbler,red-eyed vireo, andwhite-breasted nuthatch, and itsaspen groves havewoodcock. In addition to the commonly seenred-tailed hawk, other raptors include thenorthern goshawk and thegolden andbald eagles.[68][99][101]

According to the DCNR, Quehanna Wild Area is for the public "to see, use and enjoy for such activities as hiking, hunting, and fishing".[64] The main hiking trail on the Quehanna plateau is theQuehanna Trail, a 73.2-mile (117.8 km) loop trail that passes through the wild area and Moshannon and Elk State Forests. The maintrailhead for most hikers is atParker Dam State Park to the west of the wild area. From there the trail, which isblazed in orange, heads east to the southern part of Quehanna Wild Area, skirts Piper and the Boot Camp there, then turns north, crosses Wykoff Run and turns west again. After passing through Marion Brooks Natural Area, the trail leaves the wild area and completes the loop back at Parker Dam. The Quehanna Trail is considered a strenuous hike not just because of its length, but for its 9,700 feet (2,957 m) of changes in elevation. Two yellow-blazed connector trails add 30 miles (48 km) to the system, and there are many side trails and small trails off the Quehanna Highway. Most trails are open tocross-country skiing in the winter. According to the DCNR, the Quehanna Trail "passes through some of the most wild and beautiful country Pennsylvania has to offer".[107][108][109][110]
Susan Stranahan'sSusquehanna: River of Dreams reports that before Curtiss-Wright took over the area in 1955, Quehanna was considered "some of the best hunting land in the state".[8] No hunting or fishing were initially allowed on the leased land, but by July 1959 fishing on Mosquito Creek was allowed again, as was limited hunting to help control the deer. In October 1963 hunting resumed throughout the wild area, four years before the state purchased the land back from Curtiss-Wright.[111] As of 2010, the Pennsylvania Game Commission allowed hunting of the following species found in Quehanna Wild Area: American crow, beaver, black bear, black squirrel, bobcat, bobwhite quail, cottontail rabbit,coyote, elk, house sparrow,raccoon, red fox, ring-necked pheasant, ruffed grouse, white-tailed deer, wild turkey, and woodcock.[112] The Mosquito Creek Sportsmen's Association has sponsored an annual coyote hunt each winter hunt since 1992. The club has also provided food plots for deer and elk, fed game animals in winter, planted and pruned fruit trees, stocked fish, and treated streams for acid rain. Fishing is primarily for trout.[113]
The Quehanna Wild Area is also seen, used, and enjoyed bybird watchers attracted by its status as an Important Bird Area. Audubon Pennsylvania and the DCNR have prepared theSusquehanna River Birding and Wildlife Trail guide which lists three sites in Quehanna: Wykoff Run, Beaver Run Wildlife Viewing Area, and the whole wild area.[101] The DCNR has published a guide toElk Scenic Drive which lists 23 attractions, four in Quehanna: Marion Brooks and M.K. Goddard/Wykoff Run Natural Areas, and Beaver Run and Hoover Farm Wildlife Viewing Areas.[68]
Quehanna Wild Area has approximately 50 miles of shared-use trails open to horseback riding, with numerous trail heads. Some trails are quite easy, while more remote trails can be challenging. Yellowsnake Equestrian Campground near the village of Piper offers six sites geared towards horse users, albeit with very minimal facilities.[114]
