About this map

South Sister and the wider Three Sisters peaks dominate this high-altitude landscape along the border of Lane and Deschutes counties. The topography is defined by massive volcanic features and active glacial systems, including the Carver Glacier, Eugene Glacier, and Skinner Glacier. This 2014 survey documents the complex drainage patterns formed by these ice fields, feeding high lakes such as the Chambers Lakes and Moraine Lake.

Human passage through this wilderness is marked by the Pacific Crest National Scenic Trail, which snakes across the Wickiup Plain and skirts the base of Rock Mesa. To the east, the Cascade Lakes Hwy provides access to recreation sites near Devils Lake and Sparks Lake. The map illustrates a strictly preserved environment divided between the Willamette National Forest and Deschutes National Forest, where features like Separation Creek Meadow and Le Conte Crater remain largely untouched by modern development.
