Geology of Yosemite National Park, California: canyons, granitic monoliths and waterfalls.

The Yosemite National Park, which is also a world heritage site, is situated in eastern California, USA. The park occurs in a spectacular section of the Sierra Nevada and covers an area of more than 3,000 km2. The Sierra Nevada (“the range of light”) is one of the least segmented sections of the coastal ranges which extend from Alaska to Mexico. Yosemite is famed for giant canyons, or U-shaped glacial valleys, granitic monoliths, and waterfalls. Groves of giant sequoia (also known as giant redwood) are a particular feature, as is the diversity of wildlife associated with ecosystems which include montane evergreen forest and alpine moorland.
