Mount Clark is a 7,528-foot summit in The Needles of Washington’s Olympic Mountains, the second highest peak in that cluster and the seventh highest in the range overall. Its alpine runoff feeds tributaries of the Dungeness River, while its marine west coast climate brings heavy winter precipitation, wet snow, and avalanche danger; the most favorable climbing conditions usually come from July through September. First climbed on August 21, 1940, by George R. Martin and Elvin Johnson, it was then called Mount Belvedere. In 1965 it was renamed for Irving M. Clark, a Seattle conservationist who helped lead the effort to establish Olympic National Park.
