Olympic National Park is located in the U.S. state of Washington, in the Olympic Peninsula. The park can be divided into three basic regions: the Pacific coastline, the Olympic Mountains, and the temperate rainforest. U.S. President Theodore Roosevelt originally created Mount Olympus National Monument in 1909. The coastal portion of the park is a rugged, sandy beach along with a strip of adjacent forest. It is 73 miles long but just a few miles wide, with native communities at the mouths of two rivers. Within the center of Olympic National Park rise the Olympic Mountains whose sides and ridgelines are topped with massive, ancient glaciers. The western side of the park is mantled by a temperate rain forest, including the Hoh Rain Forest and Quinault Rain Forest, which receive annual precipitation of about 150 inches
