1963 Map of Dome Peak

About this map

Dome Peak and the surrounding high alpine terrain of the Cascade Range define this 1963 field-checked survey. The landscape is dominated by massive ice fields and glaciers, including the sprawling South Cascade Glacier, Dana Glacier, and Chickamin Glacier. These frozen features are the headwaters for numerous drainage systems, such as the South Fork Cascade River and Sulphur Creek. This map captures a specific moment in glaciology, showing the extent of ice before late-century retreats, and documents the intersection of three counties—Skagit, Chelan, and Snohomish. Between the sharp summits of Spire Point and Sinister Peak, small high-altitude basins hold remote water bodies like Itswoot Lake and the White Rock Lakes. The map also delineates the high-altitude boundary between the Mt Baker National Forest and Okanogan National Forest along the serrated ridges.
