Twisp Mountain

Twisp Mountain is a 7,161-foot summit in the Methow Mountains of Washington’s North Cascades, on the boundary between North Cascades National Park and the Lake Chelan-Sawtooth Wilderness. Its name belongs to a cluster that includes Twisp River, Twisp Pass, and the town of Twisp, and is usually linked to an Okanagan placename possibly referring to a wasp or yellowjacket or its sound. The mountain also reflects the larger history of the North Cascades, where tectonic and volcanic processes, terrane accretion about 50 million years ago, and repeated Pleistocene glaciation created rugged ridges, deep valleys, and a drainage divide feeding both Bridge Creek and the South Fork Twisp River.
