About this map

Mount Baker National Forest and Wenatchee National Forest converge in this high-altitude wilderness, where the Snohomish Co Chelan Co boundary traces the crest of the Cascade Range. This 2020 survey documents a landscape of extreme relief, dominated by the massif of Clark Mtn and the surrounding White Mountains. The ice-carved topography is evident in the presence of the Butterfly Glacier and Pilz Glacier, which feed high-mountain drainages including the Napeequa River and White River.

Navigation through this remote sector relies on historical routes like Little Giant Pass and Boulder Pass, which connect deep glacial valleys. The map illustrates how physical geography dictated the county lines and forest boundaries, following prominent features such as Chiwawa Ridge and Buck Mtn. This is a portrait of a preserved alpine environment, showing the complex interaction of drainage basins like Buck Cr and Boulder Cr before they descend into the lower river systems.
