1985 Map of Three Brothers

USGS Topo · Published 1986

About this map

The Continental Divide serves as the central spine of this mid-1980s mountain survey, marking the boundary between the Helena National Forest and the Deer Lodge National Forest. This high-elevation terrain is defined by a complex network of drainages and prominent summits, including Jericho Mountain and Luttrell Peak. The landscape reflects a history of small-scale resource extraction, evidenced by scattered Mine Shafts located near the headwaters of Minnehaha Creek and Tenmile Creek.
