2011 Map of South Sister

About this map

The summit of South Sister and its surrounding glacial systems dominate this high-elevation landscape in the Central Cascades. Several prominent ice masses are mapped in detail, including the Skinner Glacier, Eugene Glacier, and Prouty Glacier, which drain into high alpine basins like Teardrop Pool. The presence of the James Creek Shelter and Satan Creek Forest Camp indicates the area's significance for early 21st-century recreation and backcountry travel. Moving south from the peak, the terrain transitions into the expansive Wickiup Plain and a cluster of small water bodies such as Sisters Mirror Lake and Lancelot Lake. Geological features like Rock Mesa and The House Rock stand out against the drainage patterns of Separation Creek and James Creek. To the southeast, the Cascade Lakes Hwy provides the primary access point near Devils Lake and Talapus Butte.
