About this map

Glacier Peak Wilderness defines this high-elevation landscape, where the intersection of Skagit, Snohomish, and Chelan counties meets at the crest of the North Cascades. The map is a remarkable record of late-20th-century glaciology, detailing the expansive South Cascade Glacier, Dome Glacier, and Dana Glacier. These ice fields feed a complex drainage system including the South Fork Cascade River and Sulphur Creek, supporting isolated Gaging Stations used for hydrological monitoring.

High-altitude landmarks like Sentinel Peak, Old Guard Peak, and the namesake Dome Peak dominate the topography, surrounded by remote alpine waters such as Itswoot Lake and Cub Lake. The map illustrates the rugged transition between the Mt Baker Snoqualmie National Forest and the Wenatchee National Forest, providing a precise look at the drainage divides and passes like Ross Pass that historically dictated movement through these peaks.
