Since 1984, Yosemite has been a World Heritage Site for its granite cliffs, waterfalls, clear streams, enormous sequoia groves, lakes, mountains, meadows, glaciers, and biological variety. Just under 95% of the park is wilderness. One of Sierra Nevada’s largest and least fragmented habitats is Yosemite.
Deer and Giant Sequoias, Yosemite National Park, 1969
Granite and fragments of older rock dominate its geology. The Sierra Nevada was elevated and tilted 10 million years ago, steepening stream and river bottoms and creating deep, narrow gorges. Higher elevation glaciers formed one million years ago. They cut and molded Yosemite Valley’s U form downhill.
