Tomyhoi Peak is a 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.

The nearest higher peak is Canadian Border Peak, 2.4 miles (3.9 km) to the northeast.[1]. Precipitation runoff on the east side of the mountain drains into Tomyhoi Lake and Tomyhoi Creek, whereas the west side of the mountain drains into Damfino Creek. An unnamed 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

The Keep Kool Trail (#699) is accessed by the Twin Lakes Road (Forest Service #3065 in the North Fork Nooksack area) off of the Mount Baker Highway. The first 4.5 miles (7.2 km) to the Keep Kool trailhead is well maintained.

Climate

Tomyhoi Peak is located in the marine west coast climate zone of western North America.[3] Most weather fronts originate in the Pacific Ocean, and travel northeast toward the Cascade Mountains.

Tomyhoi Peak and Canadian Border Peak

As fronts approach the North Cascades, they are forced upward by the peaks of the Cascade Range, causing them to drop their moisture in the form of rain or snowfall onto the Cascades (Orographic lift). As a result, the west side of the North Cascades experiences high precipitation, especially during the winter months in the form of snowfall.[3] Due to its temperate climate and proximity to the Pacific Ocean, areas west of the Cascade Crest very rarely experience temperatures below 0 °F (−18 °C) or above 80 °F (27 °C).[3] During winter months, weather is usually cloudy, but, due to high pressure systems over the Pacific Ocean that intensify during summer months, there is often little or no cloud cover during the summer.[4] Because of maritime influence, snow tends to be wet and heavy, resulting in high avalanche danger.[4]
