1963 Map of Slate Peak

About this map

High-altitude mining and recreation activity define this 1963 survey of the northern Cascades, where the Okanogan National Forest and Mt Baker National Forest meet. The landscape is marked by historic mineral extraction, evidenced by the Goat Mine, Whistler Mine, and Brown Bear Mine scattered across the steep drainage basins. High mountain passes like Slate Pass and Glacier Pass provide critical passage through the high-elevation terrain, connecting deep glacial valleys such as Ninety-nine Basin and Allen Basin. A lookout tower stands atop Slate Peak, overlooking a network of early forest service infrastructure including the Harts Pass Guard Station and several remote campsites like Horse Heaven Camp. The long-distance Cascade Crest Trail winds through the center of the map, tracing the high ridges between the headwaters of the Middle Fork Pasayten River and the West Fork Methow River.
