Sequoia National Park, California, USA:



Sequoia National Park, California


Sequoia National Park is a national park in the southern Sierra Nevada east of Visalia, California, in the United States. It was established on September 25, 1890. The park spans 404,063 acres (631.35 sq mi; 1,635.18 km2). Encompassing a vertical relief of nearly 13,000 feet (4,000 m), the park contains among its natural resources the highest point in the contiguous 48 United States, Mount Whitney, at 14,505 feet (4,421 m) above sea level. The park is south of and contiguous with Kings Canyon National Park; the two are administered by the National Park Service together as the Sequoia and Kings Canyon National Parks.
The park is famous for its giant sequoia trees, including the General Sherman tree, one of the largest trees on Earth. The General Sherman tree grows in the Giant Forest, which contains five out of the ten largest trees in the world. The Giant Forest is connected by the Generals Highway to Kings Canyon National Park's General Grant Grove, home to the General Grant tree among other giant sequoias. The park's giant sequoia forests are part of 202,430 acres (81,921 ha) 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.
Many park visitors enter Sequoia National Park through its southern entrance near the town of Three Rivers at Ash 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 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 is a key transition species between the chaparral and higher elevation conifer forest.
At higher elevations in the front country, between 5,500 and 9,000 feet (1,700 and 2,700 m) 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 giant sequoia trees, the most massive living single-stem 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 squirrels, and American black bears, which sometimes break into unattended cars to eat food left by careless visitors.
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 Log 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 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.
