Mount Triumph, Summit in North Cascades National Park, Washington, United States.

Mount Triumph is a summit in North Cascades National Park that rises sharply above the surrounding landscape with three prominent rocky faces. Two small glaciers nestle beneath its eastern and northern slopes, shaping the high mountain terrain.

Lage Wernstedt, a surveyor with the U.S. Forest Service, named the peak while mapping the North Cascades. The mountain's steep faces and lack of an easy route made it a known objective among regional climbers, and the easiest line to the summit, on the west side, is rated class 4 and reached via the Triumph Pass climber's route.

Lage Wernstedt, a U.S. Forest Service surveyor, named the peak; his mapping work in the North Cascades also produced names still used on maps. The name appears in English, while Persian and Urdu forms (کوه ترایمف, ماؤنٹ ٹرائمف) circulate among regional climbing communities. Climbers know the mountain for having no easy route to the summit.

Climbing the peak involves the Northeast Ridge Route, which requires intermediate rock climbing skills and is accessed through the Thornton Lakes Trail system. Visitors should be prepared for alpine conditions and exposed terrain, especially during changing weather.

The three ridges that give Mount Triumph its propeller outline from above also shape the climbing: the northeast ridge is rated class 5.5 on generally good rock, while the easiest way up, on the west, is class 4 and dangerous when wet. The south ridge ends at Thornton Peak (6,935 ft), above the three Thornton Lakes.
