About this map

Pacific Crest National Scenic Trail traverses the high ridges of the Cascades along the boundary of Mt Baker National Forest and Wenatchee National Forest. This 1980s survey captures the landscape of the Glacier Peak Wilderness, where glacial ice and mining history intersect. Notable mining interests are documented at the Glacier Peak Mines near Miners Ridge and the Railroad Mine on the eastern slopes of the divide.

The topography is defined by significant ice bodies including Lyman Glacier, Spider Glacier, and Company Glacier. Strategic high-altitude crossings like Suiattle Pass and Cloudy Pass connect the watersheds of South Fork Agnes Creek and the Chiwawa River. Notable peaks such as Bonanza Peak and Sitting Bull Mtn tower over drainages like Buck Creek and Miners Creek, illustrating the complex drainage patterns of the North Cascades.
