Sleeping Giant (also known as theBlue Hills andMount Carmel), (Quiripi:Hobbomock),[3] is a ruggedtraprock mountain with a high point of 739 feet (225 m), located eight miles (13 km) north ofNew Haven,Connecticut. A prominent landscape feature visible for miles, the Sleeping Giant receives its name from its anthropomorphic resemblance to a slumbering human figure as seen from either the north or south. The Giant is known for its expansive clifftop vistas, rugged topography, andmicroclimate ecosystems. Most of the Giant is located withinSleeping Giant State Park.[4] The mountain is a popular recreation site: over 30 miles (48 km) ofhiking trails traverse it including 5 miles (8 km) of the 23-mile (37 km)Quinnipiac Trail.[5][6]Quinnipiac University is located at Mount Carmel's foot in Hamden.
The Sleeping Giant, 2.75 miles (4.43 km) long by 1.75 miles (2.82 km) wide, is located inHamden with its eastern edge falling intoWallingford. The Giant's profile features distinct "head," "chin," "chest," "hip," "knee," and "feet" sections topographically represented by traprock outcrops and ridge crests. The highest point is the Left Hip, 739 ft (225 m), followed by the Chest, 710 ft (220 m), and the Left Knee and Right Leg, 700 ft (210 m) each, and so on. The Giant's Head, 670 ft (200 m), is marked by a 400 ft (120 m) cliff. A stone observation tower located on the Left Hip, built by theWorks Progress Administration in the 1930s,[7] offers 360° views of the surrounding Mill andQuinnipiac River valleys. An old rock quarry, closed since 1933 and now part of the state park, has left scars on the Giant's Head.[7]
It is part of the narrow, linearMetacomet Ridge that extends fromLong Island Sound north through theConnecticut River Valley ofMassachusetts to theVermont border. The Metacomet Ridge extends west and south from Sleeping Giant as Rocky Top andWest Rock Ridge. The west side of Sleeping Giant drains into the Mill River thence to New Haven Harbor and Long Island Sound; the east side into theQuinnipiac River, thence to New Haven Harbor and Long Island Sound.[8]


Sleeping Giant, afault-block ridge that formed 200 million years ago during theTriassic andJurassic periods, is composed of traprock, also known asbasalt, anextrusivevolcanic rock. Minor earthquakes have also been measured by seismographs and reported by residents. Basalt is a dark colored rock, but the iron within it weathers to a rusty brown when exposed to the air, lending the ledges a distinct reddish appearance. Basalt frequently breaks into octagonal and pentagonal columns, creating a unique "postpile" appearance. Huge slopes made of fractured basaltscree are visible beneath many of the ledges of Sleeping Giant. The basalt cliffs are the product of several massivelava flows hundreds of feet deep that welled up in faults created by therifting apart ofNorth America fromEurasia andAfrica. These basalt floods of lava happened over a period of 20 million years. Erosion occurring between the eruptions deposited deep layers of sediment between the lava flows, which eventually lithified intosedimentary rock. The resulting "layer cake" of basalt and sedimentary sheets eventuallyfaulted and tilted upward. Subsequent erosion wore away the weaker sedimentary layers at a faster rate than the basalt layers, leaving the abruptly tilted edges of the basalt sheets exposed, creating the distinct linear ridge and dramatic cliff faces visible today. One way to imagine this is to picture a layer cake tilted slightly up with some of the frosting (the sedimentary layer) removed in between.[9]
Sleeping Giant hosts a combination ofmicroclimates unusual inNew England. Dry, hot upper ridges supportoak savannas, often dominated bychestnut oak and a variety of understory grasses and ferns.Eastern red cedar, a dry-loving species, clings to the barren edges of cliffs. Lower eastern slopes tend to supportoak-hickory forest species common in the surrounding lowlands. Narrow ravines crowded witheastern hemlock block sunlight, creating damp, cooler growing conditions with associated cooler climate plant species. Talus slopes are especially rich in nutrients and support a number of calcium-loving plants uncommon in eastern Connecticut. Because the ridge generates such varied terrain, it is the home of several plant and animal species that are state-listed or globally rare.[10] Sleeping Giant is also an important seasonalraptor migration path.[5]
According toNative Americans of theQuinnipiac Tribe, the giant stone spirit Hobbomock (or Hobomock), a prominent wicked figure in many stories (seePocumtuck Ridge andQuinnipiac), became enraged about the mistreatment of his people and stamped his foot down in anger, diverting the course of theConnecticut River (where the river suddenly swings east inMiddletown, Connecticut after several hundred miles of running due south). To prevent him from wreaking such havoc in the future, the good spirit Keitan cast a spell on Hobbomock to sleep forever as the prominent man-like form of the Sleeping Giant.[11]
In the title story ofEleanor Estes's 1948 collection,The Sleeping Giant and Other Stories, the Giant decides to get up and leave.[12] The Native American legend is retold (with a few liberties) by Jason J. Marchi in his illustrated children's bookThe Legend of Hobbomock: The Sleeping Giant, published in 2015.[13]
During the mid-19th century, spurred by the painters of theHudson River School andtranscendentalist philosophers such asRalph Waldo Emerson andHenry David Thoreau, an interest in mountains as a respite fromindustrialization andurbanization took hold in New England.[5] Summer cottages were built on the Sleeping Giant and many other locations on the Metacomet Ridge. In 1888, John H. Dickerman built acarriage road on the Giant and opened what he calledBlue Hills Park. He held picnics with ice cream on the ledges for local residents.[11]
Conservation of the Giant began in 1924 with the creation of the Sleeping Giant Park Association (SGPA) by a group of local residents concerned with ongoing traprock quarrying on the Giant's head. A cottage owner, Judge Willis Cook, had leased his property to the Mount Carmel Traprock Company for the purpose of quarrying traprock for building materials. The blasting away of what was a beloved landscape feature resulted in public outrage, well reported by local newspapers at the time. Under the leadership of James W. Toumey, aYale University forestry professor, the SGPA undertook a ten-year struggle with the traprock operation. The property was purchased by the SGPA in 1933, during the Great Depression, for $30,000; the money was raised through private donations and the property became the Sleeping Giant State Park.[14][A]
Sleeping Giant State Park was created in 1924, when the SGPA donated 600 acres to the Park and Forest Commission. The state added an additional 65 acres that year, purchased at a cost of $7025.00.[15]
In 1936, the Sleeping Giant Tower was built at the top by theWorks Progress Administration. It was listed on theNational Register of Historic Places in 1986 as part of the Connecticut State Park and Forest Depression-Era Federal Work Relief Programs Structures.[16]

On May 15, 2018, a 100-mph microburst caused extensive damage to the park, forcing its closure. Ben Lambert of the New Haven Register noted that, "The tops of trees around the park entrance looked as if they had been purposefully shorn away."[17] After more than a year of clean up, largely in part by the Sleeping Giant Park Association, the park reopened on June 14, 2019. According to the Hartford Courant, officials from the state estimated restoration cost $735,000.[18]
Sleeping Giant State Park offers clifftop views of much ofNew Haven County, some ofHartford County and, atmospheric conditions permitting, across Long Island Sound to theShoreham area onLong Island.[19]
The state park is open until sunset year-round. Activities permitted on the Giant includehiking,rock climbing,snowshoeing,picnicking,bird watching, and other passive pursuits. Trails specifically designed forhorseback riding andcross-country skiing are located on the lower reaches of the Giant, andfishing is allowed in the abutting Mill River.Rock climbing, closed on the Giant in 1953 because of accidents,[20] was permitted as of 2015.[21] Youthcamping only is allowed on the Giant (by permit). Seasonal facilities include restrooms, a picnic shelter, and picnic tables. The 23-mile (37 km)Quinnipiac Trail—the oldest trail in the 700-mile (1,100 km)blue blazed trail system managed by theConnecticut Forest and Park Association—traverses the length of the Giant from the Quinnipiac River west over the Giant's high points to the Mill River then continues north overWest Rock Ridge andMount Sanford.[19][4]
Most, but not all, of the Sleeping Giant has been conserved. The trails and facilities on Sleeping Giant are collaboratively maintained by the Sleeping Giant Park Association and the State of Connecticut, with the bulk of the trail maintenance done by the association. Sleeping Giant State Park encompasses 1,500 acres (6.1 km2); the SGPA remains active in securing additional parcels to add to the property. The SGPA has also been instrumental in defeating attempts to log the Giant, build communications towers on its summits, and close the state park altogether. SGPA runs a regular recreational and interpretive hikes on the Giant and volunteer trail maintenance programs. The Connecticut Forest and Park Association also has a working investment in the conservation of the Giant and trail building on it.[19] The trail system of the park is also designated as aNational Recreation Trail.[22]
