1985 Map of Bison Mountain

USGS Topo · Published 1986

About this map

Bison Mountain and the high peaks of the Continental Divide define this landscape where the Helena National Forest meets the Deerlodge National Forest. The 1985 survey illustrates a wilderness shaped by drainage systems like the Little Blackfoot River and Trout Creek, which carve through a series of named gulches and ridges including Baldy Ridge and Forbidden Ridge.
