1986 Map of Reas Pass

USGS Topo · Published 1986

About this map

The Continental Divide serves as the spine of this mid-1980s provisional survey, marking the high-altitude boundary between the Gallatin National Forest in Montana and the Targhee National Forest in Idaho. At the heart of this landscape lies Reas Pass, a critical point of passage through the mountainous terrain. The map traces the winding course of the Madison River and its South Fork Madison River, which drain the eastern slopes near the Fremont and Gallatin county line.
