1963 Map of Dome Peak

About this map

Dome Peak stands as the central landmark of this glaciated wilderness, situated at the convergence of several county boundaries in the high Cascades. The 1963 survey captures a landscape dominated by massive ice fields and subalpine lakes, including the expansive South Cascade Glacier and Dana Glacier. These features feed into drainages like Sulphur Creek and the South Fork Cascade River, illustrating the complex hydrology of the region. The map also delineates the high-altitude divide between the Mt Baker National Forest and Okanogan National Forest, marked by sharp summits such as Sinister Peak and Sentinel Peak. Remote water bodies like Itswoot Lake and White Rock Lakes highlight the isolated nature of the terrain before later wilderness designations altered management of these high-country basins.
