Yosemite National Park reaches across the western slopes of the Sierra Nevada Mountains. It covers an area of 747,956 acres. Yosemite is internationally recognized for its spectacular granite cliffs, waterfalls, clear streams, giant sequoia groves, and biological diversity. Almost 95% of the park is designated wilderness. It’s famed for its giant, ancient sequoias, and for Tunnel View, the iconic vista of towering Bridalveil Falls and the granite cliffs of El Capitan and Half Dome. The geology of the Yosemite area is characterized by granitic rocks and remnants of older rock.
