1968 Map of Heart Lake

USGS Topo · Published 1971

About this map

The Continental Divide winds through this high-altitude landscape where the Lolo, Lewis and Clark, and Helena National Forests converge. Mapping efforts by the U.S. Forest Service in the late 1960s detail a network of pack trails and water systems critical to the region's wilderness management. Key drainage systems like the Main Line North Fork Blackfoot River and Landers Fork are fed by numerous high-country basins including Heart Lake and Webb Lake.
