About this map

Suiattle Pass and Cloudy Pass serve as critical high-altitude crossings along the crest where Chelan and Snohomish counties meet. This 2017 survey details the complex alpine drainage systems of the Cascade Range, where the S Fork Agnes Creek flows north and the Chiwawa River begins its descent to the southeast. The landscape is defined by its glacial features and high ridges, including Miners Ridge and Lyman Ridge, which separate the deep basins of Lyman Lake and Upper Lyman Lake from the surrounding peaks.

Extensive trail systems like the Pacific Crest National Scenic Trail and the Cloudy Peak Route connect these remote basins, following the natural contours of the land. Historically significant sites such as the Crown Mine near Rubin Ridge indicate the area's prospecting legacy. The map highlights the intersection of the Wenatchee National Forest and Mount Baker National Forest, preserving a wilderness defined by prominent landmarks like Fortress Mtn, Chiwawa Mtn, and the aptly named Pass No Pass.
