1988 Map of Suiattle Pass

About this map

Glacier Peak Wilderness dominates this high-altitude landscape along the divide between Snohomish and Chelan counties. The 1988 survey documents a region defined by ice and extreme elevation, centered on the Lyman Glacier and the headwaters of the Chiwawa River and Railroad Creek. The presence of the Glacier Peak Mines on the eastern slopes of Miners Ridge points to the area's history of mineral exploration despite the difficult terrain. High-altitude routes are clearly delineated, including the Pacific Crest National Scenic Trail as it traverses Suiattle Pass and winds toward Cloudy Pass. The map serves as a record of glacial extents in the late 20th century, showing several named permanent ice fields such as Grant Glacier, Company Glacier, and Spider Glacier flanking massive summits like Bonanza Peak and North Star Mtn.
