1940 Map of Mt. Cowen

USGS Topo · Published 1958

About this map

Gallatin National Forest dominates this high-altitude landscape surveyed just before the 1940s by J. L. Lewis and F. H. Purdy. The map captures a wilderness defined by dramatic verticality, where the Boulder River cuts through the center of the sheet, fed by a dense network of glacial drainage. High peaks such as Mt Cowen, Black Mtn, and The Pyramid provide the primary landmarks for this backcountry terrain.
