Panorama - Yosemite National Park

Yosemite National Park is a United States national park lying in the western Sierra Nevada of Northern California. The park covers an area of 747,956 acres (1,168.681 sq mi; 302,687 ha; 3,026.87 km2) Designated a World Heritage Site in 1984, Yosemite is internationally recognized for its granite cliffs, waterfalls, clear streams, giant sequoia groves, lakes, mountains, glaciers, and biological diversity. Almost 95% of the park is designated wilderness.

 

On average, about 4 million people visit Yosemite each year, and most spend the majority of their time in the 5.9 square miles (15 km2) of Yosemite Valley. The park set a visitation record in 2016, surpassing 5 million visitors for the first time in its history.

 

Yosemite is one of the largest and least fragmented habitat blocks in the Sierra Nevada, and the park supports a diversity of plants and animals. The park has an elevation range from 2,127 to 13,114 feet (648 to 3,997 m) and contains five major vegetation zones: chaparral and oak woodland, lower montane forest, upper montane forest, subalpine zone, and alpine. Of California's 7,000 plant species, about 50% occur in the Sierra Nevada and more than 20% within Yosemite. There is suitable habitat for more than 160 rare plants in the park, with rare local geologic formations and unique soils characterizing the restricted ranges many of these plants occupy.

 

The geology of the Yosemite area is characterized by granitic rocks and remnants of older rock. About 10 million years ago, the Sierra Nevada was uplifted and then tilted to form its relatively gentle western slopes and the more dramatic eastern slopes. The uplift increased the steepness of stream and river beds, resulting in formation of deep, narrow canyons. About one million years ago, snow and ice accumulated, forming glaciers at the higher alpine meadows that moved down the river valleys. Ice thickness in Yosemite Valley may have reached 4,000 feet (1,200 m) during the early glacial episode. The downslope movement of the ice masses cut and sculpted the U-shaped valley that attracts so many visitors to its scenic vistas today.

 

The name "Yosemite" (meaning "killer" in Miwok) originally referred to the name of a renegade tribe which was driven out of the area (and possibly annihilated) by the Mariposa Battalion. Before then the area was called "Ahwahnee" ("big mouth") by indigenous people [Wikipedia.org]
