Mount Skokomish is a 6,434-foot peak in Washington's Olympic Mountains, rising on the boundary of Olympic National Park and the Mount Skokomish Wilderness as that wilderness area's highest point. It has three summits, with the south peak highest, and stands prominently enough to be seen on the Olympic skyline from Seattle. Runoff from its slopes feeds both the Hamma Hamma and Skokomish rivers, and its name honors the Skokomish people. The mountain is part of an Olympic range formed from obducted oceanic and sedimentary material, then shaped by Pleistocene glaciers and erosion in the wet marine west coast climate that brings especially heavy winter snowfall.
