Sequoia National Park is a national park in the southern Sierra Nevada, east of Visalia, Californiamarker, in the United States of Americamarker. It was established in 1890 as the second U.S. national park, after Yellowstone National Parkmarker. The park spans . Encompassing a vertical relief of nearly , the park contains among its natural resources the highest point in the contiguous 48 United States, Mount Whitneymarker, at above sea level. The park is south of and contiguous with Kings Canyon National Parkmarker; the two are administered by the National Park Service as one unit, called Sequoia and Kings Canyon National Parks.

The park is most famous for its Giant Sequoia trees, including the General Sherman treemarker, one of the largest trees on Earth. The General Sherman tree grows in the Giant Forestmarker, which contains five out of the ten largest trees in the world, in terms of wood volume. The Giant Forest is connected by the park's Generals Highway to Kings Canyon National Park's Grant Grovemarker, home to the General Grant treemarker among other sequoias. The park's Giant Sequoia forests are part of of old-growth forests shared by Sequoia and Kings Canyon National Parks. Indeed, the parks preserve a landscape that still resembles the southern Sierra Nevada before Euro-American settlement.

Front country



Many park visitors enter Sequoia National Park through its southern entrance near the town of Three Riversmarker at Ash Mountain at elevation. The lower elevations around Ash Mountain contain the only National Park Service-protected California Foothills ecosystem, consisting of blue oak woodlands, foothills chaparral, grasslands, yucca plants, and steep, mild river valleys. The foothills region is also home to abundant wildlife: bobcats, foxes, ground squirrels, rattlesnakes, and mule deer are commonly seen in this area, and more rarely, reclusive mountain lions are seen as well. The California Black Oak, Quercus kelloggii, is a key transition species between the chaparral and higher elevation conifer forest.

At higher elevations in the front country, between in elevation, the landscape becomes montane forest-dominated coniferous belt. Found here are Ponderosa, Jeffrey, Sugar, and Lodgepole pine trees, as well as abundant white and red fir. Found here too are the mighty Sequoia trees, the most massive living trees on earth. Between the trees, spring and summer snowmelts sometimes fan out to form lush, though delicate, meadows. In this region, visitors often see mule deer, Douglas squirrel, and American black bears, who have been known to break into unattended cars to steal food left by careless visitors.

Back country

The vast majority of the park is roadless wilderness; in fact, to the surprise of many visitors, no road crosses the Sierra Nevada within the park's boundaries. 84% of Sequoia and Kings Canyon National Parks is designated as Wilderness and is accessible only by foot or by horse.

Sequoia's backcountry offers a vast expanse of high-alpine wonders. Covering the highest-elevation region of the High Sierra, the backcountry includes Mount Whitney on the eastern border of the park, accessible from the Giant Forest via the High Sierra Trail. On a traveler's path along this backcountry trail, one passes through about of montane forest before reaching the backcountry resort of Bearpaw Meadow, just short of the Great Western Divide. Bearpaw Meadow offers rustic tent cabins and gourmet meals cooked by a seasonal resident park crew.

Continuing along the High Sierra Trail over the Great Western Divide via Kaweah Gapmarker, one passes from the Kaweah River Drainage, with its characteristic V-shaped river valleys, and into the Kern River drainage, where an ancient fault line has aided glaciers in the last ice age to create a U-shaped canyon that is almost perfectly straight for nearly . On the floor of this canyon, at least 2 days hike from the nearest road, is the Kern Canyon hot spring, a popular resting point for weary backpackers. From the floor of Kern Canyon, the trail ascends again over to the summit of Mount Whitney.

At Mount Whitney, the High Sierra Trail meets with the John Muir Trail and the epic Pacific Crest Trail, which continue northward along the Sierra crest and into the backcountry of Kings Canyon National Parkmarker.

Human history



The area which now comprises Sequoia National Park was first home to Monachee (or Western Mono) Native Americans, who resided mainly in the Kaweah River drainage in the Foothills region of the park, though evidence of seasonal habitation exists even as high as the Giant Forest. In the summertime, Native Americans 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 at Hospital Rock and Potwisha, as well as bedrock mortars used to process acorns, a staple food for the Monachee people.

By the time the first European settlers arrived in the area, smallpox had already spread to the region, decimating Native American populations. The first European settler to homestead in the area was Hale Tharp, who famously built a home out of a hollowed-out fallen Giant Sequoia log in the Giant Forest next to Log Meadow. Tharp allowed his cattle to graze the meadow, but at the same time had a respect for the grandeur of the forest and led early battles against logging in the area. From time to time, Tharp received visits from John Muir, who would stay at Tharp's log cabin. Tharp's Logmarker can still be visited today in its original location in the Giant Forest.

However, Tharp's attempts to conserve the Giant Sequoias were at first met with only limited success. In the 1880s, white settlers seeking to create a utopian society founded the Kaweah Colony, which sought economic success in trading Sequoia timber. However, Sequoia trees, unlike their Coast Redwood relatives, were later discovered to splinter easily and therefore were ill-suited to timber harvesting, though tragically thousands of trees were felled before logging operations finally ceased.

The National Park Service incorporated the Giant Forest into Sequoia National Park in 1890, the year of its founding, promptly ceasing all logging operations in the Giant Forest. The park has expanded several times over the decades to its present size; one of the most recent expansions occurred in 1978, when grassroots efforts, spearheaded by the Sierra Club, fought off attempts by the Walt Disney Corporation to purchase a high-alpine former mining site south of the park for use as a ski resort. This site was annexed to the park to become Mineral King, the highest-elevation developed site within the park and a popular destination for backpackers.

Speleology



Little known to many visitors, the park is home to over 240 known caves, and potentially hundreds more. The caves in the park include California's longest cave at over , Lilburn Cave, as well as spectacular, recently-discovered caves that remain strictly off-limits to all but a handful of specialists who visit on rare occasions to study cave geology and biology. The only cave open to park visitors remains Crystal Cavemarker, the park's second-longest at over and remarkably well-preserved for the volume of visitation it receives annually.

Park caves, like most caves in the Sierra Nevada of California, are mostly solution caves dissolved from marble. Marble rock is essentially limestone that was metamorphosed by the heat and pressure of the formation and uplift of the Sierra Nevada Batholith (ca. 50-10 million years ago). 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 ), though some caves are found in the park at elevations as high as such as the White Chief 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 currently have or have had sinking streams running through them.

Caves are discovered every year in the park; in fact, 17 have been discovered since 2003 alone. The most recently discovered major cave in the park, in September 2006, has been named Ursa Minor. Park caves are valued by scientists and cavers alike for their pristine beauty, variety, and endemic cave life.

In addition to hiking, camping, fishing, and backpacking, the following attractions are highlights with many park visitors:
  • Tunnel Log, a fallen sequoia log that automobiles can drive through;
  • Crystal Cavemarker, protected since 1918 and the only one of over 200 caves in the two adjoining parks which can be toured;
  • Crescent Meadowmarker, a Sequoia-rimmed meadow that John Muir called the "gem of the Sierra;" and
  • Moro Rockmarker, a granite outcropping near the Crescent Meadow which offers breathtaking views of the Great Western Dividemarker and the foothills of the park.
  • 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 : Atwell Mill (21 sites), Cold Springs (40 sites), Lodgepole (214 sites), and Dorst (204 sites).
