1963 Map of Crater Mountain

About this map

Mt Baker National Forest terrain dominates this 1963 survey, where high-altitude wilderness meets the upper reaches of the Skagit River watershed. The map details the complex geography of the North Cascades before the full expansion of the regional park system, centered on the towering Crater Mountain and its active Jerry Glacier. In the northwest, the Ross Lake Spillway marks the impact of hydroelectric development on the landscape, with the Ruby Arm reaching deep into the mountain valleys. Navigation through this formidable environment is defined by the Cascade Crest Trail and various alternates, connecting remote points like the Granite Creek Guard Station and the high elevations of McMillan Park. Significant peaks and ridges, including Elija Ridge and Gabriel Peak, are delineated alongside the Whatcom and Skagit County line, reflecting the area's role as a critical wilderness boundary.
