Olympic National Park is a United States national park located in the state of Washington, on the Olympic Peninsula. The park has four basic regions: the Pacific coastline, alpine areas, the west side temperate rainforest and the forests of the drier east side.
U.S. President Theodore Roosevelt originally created Mount Olympus National Monument on 2 March 1909. It was designated a national park by President Franklin Roosevelt on June 29, 1938. In 1976, Olympic National Park became an International Biosphere Reserve, and in 1981 it was designated a World Heritage Site. In 1988, Congress designated 95 percent of the park as the Olympic Wilderness.
