1959 Map of Three Sisters

USGS Topo · Published 1970

About this map

White Branch Youth Camp sits along the western edge of this High Cascades landscape, marking a point of human recreation amidst a highly active volcanic and glacial environment. The boundary between the Willamette National Forest and Deschutes National Forest bisects a terrain defined by dramatic peaks and extensive lava fields, including Yapoah Crater and the Obsidian Cliffs. The map documents several high-altitude refuge points such as Sunshine Shelter and James Creek Shelter, alongside memorials like the Montague Memorial Plaque and Prouty Memorial Plaque. Water features are abundant, from the well-known Proxy Falls and Linton Falls to numerous alpine basins like Benson Lake and Tenas Lakes, reflecting the complex drainage patterns of Foley Ridge and the surrounding volcanic plateau.
