1987 Map of Eighteenmile Peak

USGS Topo · Published 1987

About this map

The Continental Divide snake across this high-altitude landscape where the borders of Beaverhead and Lemhi counties meet the Montana-Idaho state line. Dominated by the soaring profile of Eighteenmile Peak, the terrain is defined by deep drainage systems like Montana Canyon and Ramsey Canyon that feed into the larger river valleys below. The boundary between the Beaverhead National Forest and Targhee National Forest underscores the protected, wilderness character of this region during the 1980s.
