1970 Map of Three Sisters

USGS Topo · Published 1973

About this map

The Continental Divide serves as the central spine of this 1970 survey, defining the high-altitude boundary between Flathead Co and Lewis and Clark Co. This primitive mountain landscape is preserved within the Bob Marshall Wilderness, where the drainage patterns of the Spotted Bear River and Sun River Game Preserve are intricately mapped. Notable peaks including Hahn Peak, Lick Mountain, and Lookout Mountain dominate the terrain, while the namesake Three Sisters and Three Sisters Creek anchor the southern portion of the sheet.
