Olympic National Park, established by President Franklin D. Roosevelt on June 29, 1938, is a globally renowned natural reserve located on Washington State’s Olympic Peninsula, spanning approximately 922,650 acres[1][6]. The park showcases three distinct ecosystems—glaciated mountains, temperate rainforests, and rugged Pacific coastline—making it a unique and diverse natural habitat[6]. It contains some of the best examples of intact temperate rainforests in the continental US, a vast wilderness area covering over 95% of the park, and the longest undeveloped coastline in the contiguous United States[4][6]. The park’s history stretches back over 13,500 years of human occupation, with indigenous peoples skillfully managing its resources long before European contact[3][2]. The Olympic Peninsula was initially designated as the Olympic Forest Reserve in 1897, then Mount Olympus National Monument in 1909 under President Theodore Roosevelt to protect Roosevelt Elk habitat[3][7]. Roosevelt’s successor, Franklin D. Roosevelt, further supported its protection, culminating in the national park designation in 1938 after his visit to the region in 1937[1][4]. The Civilian Conservation Corps contributed significantly during the 1930s and 40s by developing infrastructure such as roads and campgrounds within the park[5]. Olympic National Park has achieved international recognition for its outstanding natural value. UNESCO designated it an International Biosphere Reserve in 1976 and a World Heritage Site in 1981, highlighting its ecological and cultural significance[3][6][10]. The park preserves over 650 archaeological sites and numerous historic areas, documenting thousands of years of human history and ongoing cultural heritage[3]. Today, Olympic National Park serves as a vital conservation area and a premier destination for outdoor recreation including hiking, fishing, boating, and wildlife observation. Its management balances preservation of its diverse ecosystems with providing access to millions of visitors annually, makin
