/fljwitntoMik/ NATIONAL PARK Washington The National Park System, of which this park is a unit, is dedicated to conserving the scenic, scientific, and historic heritage of the United States for the benefit and enjoyment of its people. Historic Events 1792 Capt. George Vancouver, of the Royal British Navy, first white man to record sight of "The Mountain," named it Mount Rainier in honor of his friend, Admiral Peter Rainier. 1833 l-)r- William Fraser Tolmie entered northwest corner of what is now the park.

Van Trump made the first successful ascent via Gibraltar route. 1890 7he first woman, Fay Fuller, reached the summit of Mount Rainier. 1899 Mount Rainier National Park established by act of Congress. 1913 Elevation of Mount Rainier established as 14,408 feet above sea level by the Geological Survey, United States Department of the Interior. 1915 First public travel by automobile to Paradise Valley. 1916 National Park Service established in the United States Department of the Interior to administer the national parks and national monuments. 1931 Road completed to Sunrise, Yakima Park. 1940 East Side Highway completed. WILD ANIMALS It is dangerous for you to get near wild animals though they may appear tame. Some have become accustomed to humans but they still are wild and may seriously injure you if you approach them. Regulations prohibiting feeding, teasing, touching, or molesting wild animals are enforced for your own safety. COVER: Mount Rainier from Mirror Lake, Indian Henrys Hunting Ground.
