Many park visitors enter Sequoia National Park through its southern entrance near the town ofThree Rivers atAsh Mountain at 1,700 ft (520 m) elevation. The lower elevations around Ash Mountain contain the only National Park Service-protected California Foothills ecosystem, consisting ofblue oak woodlands, foothillschaparral, grasslands,yucca plants, and steep, mild river valleys. Seasonal weather results in a changing landscape throughout the foothills with hot summer yielding an arid landscape while spring and winter rains result in blossoming wildflowers and lush greens.[8] The region is also home to abundant wildlife:bobcats,foxes,ground squirrels,rattlesnakes, andmule deer are commonly seen in this area, and more rarely, reclusivemountain lions and the Pacificfisher are seen as well. The lastCalifornia grizzly was killed in this park in 1922 (at Horse Corral Meadow).[9] TheCalifornia Black Oak is a key transition species between the chaparral and higher elevationconifer forest.[10]
At higher elevations in the front country, between 5,500 and 9,000 feet (1,700 and 2,700 m) in elevation, the landscape becomesmontane forest-dominated coniferous belt. Found here arePonderosa,Jeffrey,sugar, andlodgepole pine trees, as well as abundantwhite andred fir. Found here too are thegiant sequoia trees, the most massive living single-stem trees on Earth. Between the trees, spring and summersnowmelts sometimes fan out to form lush, though delicate, meadows. In this region, visitors often see mule deer,Douglas squirrels, andAmerican black bears, which sometimes break into unattended cars to eat food left by careless visitors. There are plans to reintroduce thebighorn sheep to this park.[11]
The vast majority of the park is road-less wilderness; no road crosses the Sierra Nevada within the park's boundaries. 84 percent of Sequoia and Kings Canyon National Parks isdesignated wilderness[12] and is accessible only by foot or by horseback. The majority was designated Sequoia-Kings Canyon Wilderness in 1984[13] and the southwest portion was protected asJohn Krebs Wilderness in 2009.[14]
The area which now is Sequoia National Park shows evidence of Native American settlement as early as AD 1000.[15] The area was first home to "Monachee" (Western Mono)Native Americans, who resided mainly in theKaweah River drainage in the Foothills region of what is now the park, though evidence of seasonal habitation exists as high as the Giant Forest. Members of this tribe were permanent residents of the park, with a population estimate of around 2,000.[15] In the summer theTubatulabal Native Americans used the eastern part of the area (the Kern River drainage) as their summer hunting grounds.[16] During this time, the Western Mono tribe would travel over the high mountain passes to trade with tribes to the East. To this day,pictographs can be found at several sites within the park, notably atHospital Rock and Potwisha, as well as bedrock mortars used to processacorns, a staple food for the Monachee people.
Tharp's Log, a cabin formed out of a hollowed-outgiant sequoia log
The first European settler to homestead in the area wasHale Tharp, who built a home out of a hollowed-out fallen giant sequoia log in the Giant Forest next to Log Meadow. Tharp arrived in 1858 to the region and encountered several groups of Native Americans, the largest being around 600 with several other smaller groups found at higher elevations.[15] After becoming friendly with the Western Mono tribe, Tharp was shown the Giant Forest Sequoia Grove. After his settlement, more settlers came around 1860.
Shortly thereafter - between 1860 and 1863, epidemics of smallpox, measles, and scarlet fever killed the majority of the Native Americans living in the area. After this, the rest of the Native Americans left with the largest campsite (Hospital Rock) abandoned by 1865.[15] During their time in the area, the Monachee used periodic fire burning to aid in hunting and agriculture. This technique played an important role in the ecology of the region and allowed for a "natural" vegetation cover development.[15] After they left, Tharp and other settlers allowed sheep and cattle to graze the meadow, while at the same time maintaining a respect for the grandeur of the forest and led early battles against logging in the area. From time to time, Tharp received visits fromJohn Muir, who would stay at Tharp's log cabin.Tharp's Log can still be visited today in its original location in the Giant Forest.
Sequoia National Park
Long title
An Act to set apart a certain tract of land in the State of California as a public park.
Tharp's attempts to conserve the giant sequoias were at first met with only limited success. In the 1880s, white settlers seeking to create autopian society founded theKaweah Colony, which sought economic success in trading Sequoia timber. Giant Sequoia trees, unlike theircoast redwood relatives, were later discovered to splinter easily and therefore were ill-suited to timber harvesting, though thousands of trees were felled before logging operations finally ceased.
President Benjamin Harrison ultimately signed legislation that established the Sequoia National Park on 25 September 1890, becoming the second national park established in the United States, and ending logging in the area.[17][18]
Another consequence of the Giant Forest becoming Sequoia National Park was the shift in park employment. Prior to the incorporation by the National Park Service, the park was managed by US army troops of the 24th Regiment of Infantry and the 9th Regiment of Cavalry, better known as theBuffalo Soldiers.[19] These segregated troops, founded in 1866, were African-American men from the South, an invaluable demographic to the military with the lowest rates of desertion. The Buffalo Soldiers completed park infrastructure projects as well as park management duties, helping to shape the role of the modern-day park ranger. The Buffalo Soldiers rose to this position due to a lack of funding for the park which led to an inability to hire civilians.[20]
A boulder found in Sequoia National Park honoring Captain Charles Young.
The third African American West Point graduate, CaptainCharles Young led the cavalries of Buffalo Soldiers in the Sequoia and General Grant Parks. Young landed this post as a result of the segregation rampant throughout the Army: as a black man, he was not permitted to head any combat units.[21] He did demonstrate his leadership capability through his initiatives in the national park delegating park infrastructure projects, hosting tourists and politicians, and setting a standard of a strong work ethic into his men. Young was also a prominent figure regarding the early conservation of Sequoia National Park. He greenlighted the dedication of trees in honor of prominent figures as a means of promoting their preservation. One such example is the Redwood dedicated to the escaped slave and activist,Booker T Washington. Young also argued to the Secretary of the Interior that the lack of enforcement of forest protection laws allowed the detrimental practices of logging and the popular tourist hobby of carving names into the redwoods to continue.[20]
An expansions occurred in 1978, when grassroots efforts, spearheaded by theSierra Club, fought off attempts by theWalt Disney Company to purchase a high-alpine former mining site south of the park for use as a ski resort.[22] This site known asMineral King was annexed to the park.[23] Its name dates back to early 1873 when the miners in the area formed the Mineral King Mining District.[24] Mineral King is the highest-elevation developed site within the park and a popular destination for backpackers.
Sequoia National Park contains a significant portion of theSierra Nevada. The park's mountainous landscape includes the tallest mountain in the contiguous United States, Mount Whitney, which rises to 14,505 feet (4,421 m) above sea level.[35] TheGreat Western Divide parallels the Sierran crest and is visible at various places in the park, for example,Mineral King,Moro Rock, and theGiant Forest. Peaks in the Great Western Divide rise to more than 12,000 feet (3,700 m). Deep canyons lie between the mountains, including Tokopah Valley above Lodgepole, Deep Canyon on the Marble Fork of theKaweah River, andKern Canyon in the park's backcountry, which is more than 5,000 feet (1,500 m) deep for 30 miles (50 km).[36]
Most of the mountains and canyons in the Sierra Nevada are composed ofgranitic rocks. These rocks, such asgranite,diorite andmonzonite, formed whenmolten rock cooled far beneath the surface of the earth. The molten rock was the result of a geologic process known assubduction. Powerful forces in the earth forced the landmass under the waters of the Pacific Ocean beneath and below an advancingNorth American Continent. Super-hot water driven from the subducting ocean floor migrated upward and melted rock as it proceeded. This process took place during theCretaceous Period, 100 million years ago. Granitic rocks have a speckled salt-and-pepper appearance because they contain various minerals includingquartz,feldspars andmicas. Valhalla, or the Angel Wings, are prominent granitic cliffs that rise above the headwaters of the Middle Fork of theKaweah River.[36]
The Sierra Nevada is a young mountain range, probably not more than 10 million years old. Forces in the earth, probably associated with the development of theGreat Basin, forced the mountains to rise. During the last 10 million years, at least fourice ages have coated the mountains in a thick mantle of ice. Glaciers form and develop during long periods of cool and wet weather. Glaciers move very slowly through the mountains, carving deep valleys and craggy peaks. The extensive history of glaciation within the range and the erosion-resistant nature of the granitic rocks that make up most of the Sierra Nevada have together created a landscape of hanging valleys, waterfalls, craggy peaks, alpine lakes (such asTulainyo Lake) and glacial canyons.[36]
Park caves, like most caves in the Sierra Nevada of California, are mostlysolutional caves dissolved frommarble. Marble rock is essentiallylimestone that wasmetamorphosed by the heat and pressure of the formation and uplift of theSierra Nevada Batholith. The batholith's rapid uplift over the past 10 million years led to a rapid erosion of the metamorphic rocks in the higher elevations, exposing the granite beneath; therefore, most Sierra Nevada caves are found in the middle and lower elevations (below 7,000 ft or 2,100 m), though some caves are found in the park at elevations as high as 10,000 ft (3,000 m) such as the White Chief cave and Cirque Cave in Mineral King. These caves are carved out of the rock by the abundant seasonal streams in the park. Most of the larger park caves have, or have had, sinking streams running through them.
The park contains more than 270 known caves, including Lilburn Cave which is California's longest cave with nearly 17 miles (27 km) of surveyed passages.[36] The only commercial cave open to park visitors isCrystal Cave, the park's second-longest cave at over 3.4 miles (5.5 km). Crystal Cave was discovered on April 28, 1918, by Alex Medley and Cassius Webster.[37] The cave is a constant 48 °F (9 °C), and is only accessible by guided tour.
Caves are discovered frequently in the park with the most recently discovered major cave beingUrsa Minor in August 2006.[38][39]
Crescent Meadow in the Giant Forest, called the "Gem of the Sierra" byJohn Muir
Sequoia National Park encompasses many classifications of ecological zones, with the highest zone consisting ofalpine tundra vegetation, then followed by California conifer forests, withchaparral at the lower elevations of the park.[40]
In the early 2000s, lumber company,Sierra Pacific Industries, began creating a living gene bank of trees using seeds harvested from the park.[41]
In addition to hiking, camping, fishing, and backpacking, the following attractions are highlights with many park visitors:
Sherman Tree Trail An 0.8-mile roundtrip paved trail that descends from the parking lot to the base of theGeneral Sherman Tree and meanders through a grove of giant sequoia trees.
Tunnel Log is a fallen giant sequoia tree in Sequoia National Park. The tree, which measured 275 feet (84 m) tall and 21 feet (6.4 m) in diameter, fell across a park road in 1937 due to natural causes. The following year, a crew cut an 8-foot (2.4 m) tall, 17-foot (5.2 m) wide tunnel through the trunk, making the road passable again.[43][44][45]
Tokopah Falls The trail to Tokopah Falls starts just beyond the Marble Fork Bridge in Lodgepole Campground. It is an easy 1.7 mile (one way) walk along the Marble Fork of the Kaweah River to the impressive granite cliffs and waterfall of Tokopah Canyon. Tokopah Falls is 1,200 feet (370 meters) high, and is most impressive in early summer.
Crescent Meadow is a small, sequoia-rimmed meadow in the Giant Forest region of Sequoia National Park. This sierran montane meadow marks the western terminus of the High Sierra Trail, which stretches from the meadow across the Great Western Divide to Mount Whitney. Pioneer Hale Tharp homesteaded in this and nearby Log Meadow. Conservationist John Muir visited this meadow many times and called it the "Gem of the Sierra". The meadow lies at the end of a three-mile paved road which leaves the Generals Highway near theGiant Forest Museum.
Moro Rock is agranite dome located in the center of the park, at the head ofMoro Creek, between Giant Forest and Crescent Meadow. A 351-step stairway, built in the 1930s by theCivilian Conservation Corps, is cut into and poured onto the rock, so that visitors can hike to the top. Thestairway is listed on theNational Register of Historic Places. The view from the rock encompasses much of the park, including the Great Western Divide. It has an elevation of 6,725 feet (2,050 m).
Campgrounds in the park include three in the foothills area: Potwisha (42 sites), Buckeye Flat (28 sites), and South Fork (10 sites). Four campgrounds are at higher,conifer-dominated elevations, ranging from 6,650 to 7,500 feet (2,000 to 2,300 m): Atwell Mill (21 sites), Cold Springs (40 sites), Lodgepole (214 sites), and Dorst Creek (204 sites).
