Arrowhead Mountain is a mountain summit located in Chelan County of Washington state. It is situated east of Stevens Pass, on the boundary of Alpine Lakes Wilderness, on land managed by Okanogan-Wenatchee National Forest. Arrowhead Mountain is part of the Chiwaukum Mountains, which are a subset of the Cascade Range. Its nearest higher neighbor is Jim Hill Mountain, to the southwest. Precipitation runoff from the peak drains into tributaries of Nason Creek, which in turn is a tributary of the Wenatchee River. This mountain was named by Albert Hale Sylvester (1871-1944), a pioneering surveyor, explorer, topographer, and forest supervisor who named hundreds of natural features in the Cascades.
