About this map

Miners Ridge and the high summits of the Cascade Range define this 2020 map of the borderlands between Snohomish and Chelan counties. The terrain is characterized by massive ice features and significant elevation changes, from Lyman Glacier and Spider Glacier to the peaks of Chiwawa Mtn and Sitting Bull Mtn. This area serves as a critical junction for high-altitude passage, including Suiattle Pass, Cloudy Pass, and Buck Creek Pass, all woven together by the Pacific Crest National Scenic Trail.

Tracing the routes reveals historical human activity in this demanding environment, such as the Crown Mine near Railroad Cr and the presence of Sheep Camp below Mid Ridge. These labels, alongside remote landmarks like Helmet Butte and Flower Dome, suggest a legacy of both resource extraction and seasonal grazing. The hydrology is equally complex, with the headwaters of the Chiwawa River and S Fork Agnes Creek draining these glaciated slopes within the Mount Baker and Wenatchee National Forests.
