1970 Map of Trap Mountain

USGS Topo · Published 1973

About this map

The Continental Divide winds through this high-altitude landscape on the border of Lewis and Clark and Powell Counties. Documented in the early 1970s, the terrain is defined by the convergence of the Bob Marshall Wilderness and the Sun River Game Preserve. The absence of established land lines reflects the remote character of this protected backcountry, where human presence is marked only by isolated outposts like the Basin Creek Guard Station and a network of named routes including the Jumbo Lookout Trail.
