Suiattle Pass serves as a critical geographic junction on the boundary between Snohomish and Chelan counties. This high-altitude landscape is defined by the massive glacial ice of the Lyman Glacier, Spider Glacier, and Grant Glacier, which feed into high-mountain drainage systems like the Chiwawa River and Railroad Cr. The map captures the course of the Pacific Crest National Scenic Trail as it winds through the Wenatchee National Forest and Mount Baker National Forest. Landforms such as Cloudy Peak, Fortress Mtn, and the distinctive Helmet Butte dominate the skyline. Human presence is largely limited to the seasonal Lady Camp and the network of primitive routes crossing gaps like Buck Creek Pass and the oddly named Pass No Pass. This survey provides a precise look at the hydrology of the North Cascades, including the waters of Lyman Lake and Massie Lake before they descend into the narrow valleys below.
