California’s diverse geography ranges from the hard, rocky beaches of the Pacific coast to the rugged, snow-capped Sierra Nevada mountains in the east. The central portion of the state is dominated by the Central Valley, one of the most productive agricultural areas in the world. The Sierra Nevada contains Yosemite Valley, famous for its glacially-carved domes, and Sequoia National Park, home to the largest living organisms on Earth, the giant sequoia trees, and the highest point in the contiguous United States, Mount Whitney. The tallest living things on Earth, the ancient redwood trees, dot the coastline, mainly north of San Francisco. California is also home to the second lowest and hottest place in the Western Hemisphere, Death Valley. Bristlecone pines located in the White Mountains are the oldest known trees in the world; one has an age of 4,700 years.
