Pasayten Wilderness and Mt Baker National Forest terrain dominates this 1960s survey of the high cascades, where the drainage divides of Whatcom and Okanogan counties meet. The landscape is defined by an intricate network of pack trails, including the Pacific Crest Scenic Trail, which threads through high-altitude gaps like Sky Pilot Pass and Rock Pass. These routes provided the primary access for Forest Service management and backcountry travel long before modern road development.
