About this map

Ross Lake dominates the central corridor of this wilderness survey, serving as the interface between several protected federal lands. The landscape is defined by its dramatic relief, where the North Cascades National Park meets the Ross Lake National Recreation Area and the Mount Baker National Forest. High-altitude water bodies like Skymo Lake and Sourdough Lake are situated in the high basins, feeding a network of drainages including Skymo Cr and Big Beaver Creek.

Evidence of backcountry transit is found in the Pacific NW National Scenic Trail, which skirts the eastern shore of the reservoir and traverses the slopes near Pumpkin Mtn. Landmarks within the water, such as Tenmile Island, Little Jerusalem Island, and Cougar Island, provide navigational reference points in this largely roadless area. The mapping of Roland Point and Roland Cr further delineates the complex shoreline and drainage patterns of the upper Skagit River watershed.
