1963 Map of Slate Peak

About this map

Slate Peak and the high ridges of the North Cascades define this 1963 survey, where the boundaries of Mt Baker National Forest and Okanogan National Forest converge. This mountain landscape is marked by a history of high-altitude extraction, evidenced by the Illinois Mine, Goat Mine, and Brown Bear Mine located along steep drainage basins. Transportation across this demanding terrain relies on the Cascade Crest Trail and the West Fork Methow Trail, connecting remote outposts like the Guard Station and the Lookout Tower near the summit of Slate Peak. Seasonal camps such as Deer Park Camp and Horse Heaven Camp illustrate the era's recreational and administrative use of the wilderness, while the headwaters of the Methow River and Middle Fork Pasayten River originate from these glacial divides.
