Tomyhoi Peak

Tomyhoi Peak is a 7,439-foot (2,267-metre) Skagit Range mountain situated one mile south of the Canada–United States border, in the North Cascades of Washington state. It is located west of Mount Larrabee and within the Mount Baker Wilderness, which is part of the Mount Baker-Snoqualmie National Forest. This mountain's toponym was officially adopted in 1913 by the U.S. Board on Geographic Names.

The nearest higher peak is Canadian Border Peak, 2.4 miles (3.9 km) to the northeast. Precipitation runoff on the east side of Tomyhoi Peak drains into Tomyhoi Lake and Tomyhoi Creek, whereas the west side of the mountain drains into Damfino Creek, all eventually reaching the Chilliwack River in Canada. Tomyhoi Peak is more notable for its large, steep rise above local terrain than for its absolute elevation. Topographic relief is significant as the summit rises over 4,400 feet (1,300 meters) above Damfino Creek in one mile (1.6 km). The unofficially named Tomyhoi Glacier lies on its north flank. The summit offers views of Mount Larrabee, American Border Peak, Canadian Border Peak, Mount Shuksan, and Mount Baker. Access is via the Keep Kool Trail (#699), from the Twin Lakes Road (Forest Service #3065) off of the Mount Baker Highway.
