Whitehorse Mtn and the So-Bahli-Alhi Glacier dominate this vertical landscape within the Boulder River Wilderness. The area is defined by sharp elevation changes and deep basins, including the Wellman Basin and Sill Basin, where high-altitude water bodies like Tucker Lake and Bullen Lake are fed by glacial runoff. The map detail highlights the challenging topography of Whitehorse Ridge and Boulder Ridge, which separate the various creek systems including Gerkman Creek and French Creek.
