About: Copper Mountain (Mason County, Washington)

Copper Mountain is a 5,425-foot (1,654 m) mountain summit located in the southeast portion of the Olympic Mountains, in Mason County of Washington state. It is situated on the boundary shared by Daniel J. Evans Wilderness and Mount Skokomish Wilderness, as well as the shared common border of Olympic National Park with Olympic National Forest. The nearest higher neighbor is Mount Ellinor, 1.67 miles (2.69 km) to the east. Wagonwheel Lake lies immediately north of the peak. Topographic relief is significant as the summit rises nearly 4,700 feet (1,400 m) above the Staircase Ranger Station at Lake Cushman in approximately 1.5 miles (2.4 km). Precipitation runoff from the mountain drains north into the Hamma Hamma River, and south into the North Fork Skokomish River, thence Lake Cushman.
