1966 Map of Gem Peak

USGS Topo · Published 1984

About this map

Gem Peak anchors a remote stretch of the Bitterroot Range, marking the high-altitude divide between the Kaniksu National Forest and Coeur d'Alene National Forest. This 1966 survey, updated with 1980s aerial data, captures a landscape defined by sharp ridges and deep drainage basins along the Idaho-Montana border. A lookout tower and radio facility atop high points like Eighty Peak emphasize the importance of fire surveillance and communication in these heavily wooded corridors during the mid-to-late 20th century.
