Whitehorse Ridge and the high peaks of the Mt Baker National Forest dominate this late-1980s provisional study of Snohomish County. The landscape is defined by its glacial features and vertical relief, prominently featuring the So-Bahli-Ahli Glacier on the slopes of Whitehorse Mountain and the Queest-Alb Glacier near the summit of Three Fingers. The intricate drainage network of Squire Creek and the Boulder River illustrates the hydrology of the Boulder River Wilderness, where steep canyons like South Fork Canyon Creek cut through the terrain. This map serves as a detailed record of the high country before modern shifts in glacial margins, capturing specific high-altitude landmarks such as Goat Flat, Tin Can Gap, and the remote Craig Lakes.
