1986 Map of Madison Arm

USGS Topo · Published 1986

About this map

Hebgen Lake and its prominent Madison Arm dominate the high-altitude topography of this Montana-Idaho border region during the mid-1980s. The landscape is defined by the convergence of the Gallatin National Forest and Targhee National Forest, split by the Continental Divide as it winds through Gallatin and Fremont Counties. The map records the hydraulic complex of the South Fork Madison River and the sweeping Madison Valley, where the terrain transitions from the water's edge to the mountain crests.
