1956 Map of Grassy Lake Reservoir

About this map

The rugged intersection of three major protected wilderness areas—Yellowstone National Park, Targhee National Forest, and Grand Teton National Park—comes into focus in this mid-1950s survey. The landscape is defined by the complex water systems of the Falls River Basin, where the Bechler River drops through Bechler Canyon over notable heights such as Colonnade Falls and Iris Falls. Evidence of early land use and high-altitude activity appears at the Lucky Lady Mine near Grizzly Creek and the remote Patrol Cabin situated near the Teton Co boundary.
