1963 Map of Dome Peak

About this map

Dome Peak and the high glaciated ridges of the North Cascades define this 1963 field-checked survey. The landscape is dominated by the convergence of three counties—Chelan, Skagit, and Snohomish—meeting at sharp summits like Sinister Peak. Massive ice fields such as the South Cascade, Dana Glacier, and Chickamin Glacier flow from the peaks, feeding headwaters for the South Fork Cascade River and Agnes Creek. This map records a purely high-alpine environment before modern climate shifts, detailing the exact reach of permanent snow and ice across landmarks like Sentinel Peak and Old Guard Peak. The topographic detail traces the drainage patterns from White Rock Lakes and Itswoot Lake, illustrating the difficult passage through high-altitude gaps such as Ross Pass and the steep terrain of Mt Baker National Forest.
