2023 Map of Clark Mountain

About this map

The crest of the White Mountains and the high ridges of the Cascades dominate this contemporary survey of the Glacier Peak Wilderness along the border of Snohomish and Chelan counties. The map illustrates a high-altitude landscape defined by perennial ice and steep drainages, including the Butterfly Glacier and Pilz Glacier perched on the western slopes of Clark Mtn. This area serves as a critical watershed for the North Cascades, where the Napeequa River and Chiwawa River begin their descent through deep glacial valleys.
