Salmo-Priest Wilderness, Wilderness area in the Selkirk Mountains, Washington, United States

Salmo-Priest Wilderness is a protected forest area in northeastern Washington with two mountain ridges that meet at Salmo Mountain. The terrain features thick timber and open meadows spread across the interconnected ridges.

Salmo-Priest Wilderness was one of 19 areas designated under the Washington Wilderness Act, signed into federal law in 1984. Its protection followed a 20-year campaign led by Spokane Mountaineers club president Ray Kresek and local conservationists against logging and development. The area was chosen over a Kettle River Range proposal because of its boreal woodland caribou habitat, the last in the contiguous United States.

The wilderness lies in the Selkirk Mountains, which the sources name as the last refuge for woodland caribou in the contiguous United States. The area also appears as the fictional town of Twin Peaks in the ABC television series of the same name, first broadcast from 1990 to 1992.

Hikers can use a network of trails including the Shedroof Divide Trail that crosses both mountain ridges. The paths pass through varied terrain and require sturdy footwear and readiness for changing weather.

The wilderness contains the largest old-growth forest in eastern Washington. Its creation was driven by a 20-year campaign led by Ray Kresek, president of the Spokane Mountaineers, and local conservationists who sought to keep the area from logging and development. Salmo-Priest was chosen over a proposal in the Kettle River Range because of its boreal woodland caribou habitat, the last in the contiguous United States.
