About this map

South Sister and the surrounding high peaks of the Cascade Range dominate this 2017 survey, where the border of Lane Co and Deschutes Co follows the crest of the mountains. This alpine environment is defined by its numerous active ice fields, including Skinner Glacier, Eugene Glacier, and Prouty Glacier situated near Hodge Crest. The topographic detail highlights the volcanic origins of the landscape, from the prominent Rock Mesa and Le Conte Crater to the broad expanse of the Wickiup Plain.

Modern recreational infrastructure is mapped alongside these natural landmarks, showing the Pacific Crest National Scenic Trail as it winds past Sisters Mirror Lake and The House Rock. Climbers and hikers can trace the S Sister Climber route and the Moraine Lake trail network through both the Willamette National Forest and Deschutes National Forest. The map also identifies high-elevation wetlands and meadows such as Separation Creek Meadow and Cole Chuck Meadow, which serve as vital ecological components of this protected wilderness.
