Trappers Peak is a 5,966-foot (1,818 m) elevation mountain summit located in the North Cascades of Washington state. It is situated within North Cascades National Park, Stephen Mather Wilderness, and Whatcom County. It rises steeply above Lower Thornton Lake which is set at the southwestern face of the mountain. Like many North Cascades peaks, Trappers Peak is more notable for its large, steep rise above local terrain than for its absolute elevation. Topographic relief is significant as the southeast aspect rises 5,500 feet (1,700 m) above the North Cascades Highway in approximately two miles. The nearest higher neighbor is Thornton Peak, 1.5 miles (2.4 km) to the northwest, Mount Triumph is two miles to the northwest, and Newhalem is three miles to the east-southeast. Precipitation runoff
