1970 Map of Prairie Reef

USGS Topo · Published 1992

About this map

Bob Marshall Wilderness and the Sun River Game Preserve dominate this high-altitude landscape in the northern Rockies. The area, mapped in the late 1960s, serves as a crucial corridor for wildlife and watershed protection, defined by the towering Chinese Wall and the peak of Prairie Reef. A network of historic pack trails provides the only access through these protected lands, connecting remote landmarks such as the Prairie Reef Lookout and the Indian Point Guard Station.
