Timelapse shot of magnificent Yosemite Park, located in Sierra Nevada mountains in California USA. On average, about 4 million people visit Yosemite each year. 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 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.
