Mount Skokomish Wilderness, Nature reserve in Mason County, US

Mount Skokomish Wilderness is a 13,291-acre protected area in Olympic National Forest, just north of Lake Cushman. It consists of two long rocky ridges running northeast to southwest, from about 2,000 feet up to 6,434 feet at Mount Skokomish on the northwest boundary. The northern ridge rises to Mounts Skokomish, Lincoln and Cruiser, with Sawtooth Ridge between Lincoln and Cruiser; the southern ridge includes Mounts Pershing, Washington, Rose, Ellinor, Jefferson Peak and Tran Spire.

Congress established Mount Skokomish Wilderness in 1984 as one of five wilderness areas created that year in Olympic National Forest, alongside Buckhorn, Colonel Bob, The Brothers and Wonder Mountain. It lies along the southeast flank of the Olympic Wilderness, which was added in 1988. The U.S. Forest Service administers its 13,291 acres.

The Hamma Hamma River, which drains the wilderness, takes its name from the Twana word for the area around Hood Canal, the homeland of the Skokomish people. The name Mount Skokomish itself comes from that people. Visitors today walk trails like the Putvin and Mildred Lakes routes through land the Skokomish knew as their river country.

Access is mainly through hiking trails, with the Mildred Lakes Trail being a primary route that involves steep climbing. Visitors should expect no facilities, changing weather, and dense forest vegetation throughout.

Sawtooth Ridge is a rock-climbing site on the northern ridge, running between Mount Lincoln and Mount Cruiser. The two long rocky ridges of the wilderness run roughly northeast to southwest, and the ridge tops stand above the old-growth hemlock, cedar and Douglas fir of the lower slopes.
