2014 Map of Cascade Pass

About this map

Cascade Pass serves as the central high-altitude crossing point on this survey, marking the intersection of North Cascades National Park, Mount Baker National Forest, and Wenatchee National Forest. The map documents a landscape defined by dramatic glaciated peaks and high alpine lakes at the boundary of Skagit and Chelan counties. High-elevation water systems are prominent, including the vast Boston Glacier and the Quien Sabe Glacier, which feed into drainage basins like the Stehekin River and the S Fork Cascade River. Mountaineering landmarks such as Johannesburg Mtn, Sahale Mtn, and the technical Sprenger Spires are detailed alongside remote water bodies like Doubtful Lake and the Yang Yang Lakes. The survey also captures the steep descent into Horseshoe Basin and the narrow passage through Box Canyon, illustrating the challenging connectivity of the northern Cascade Range.
