1966 Map of Jumbo Mountain

USGS Topo · Published 1970

About this map

Beaverhead National Forest defines this high-elevation landscape along the border of Montana and Idaho. The Continental Divide winds through the southwestern corner, serving as a natural boundary between the Salmon National Forest and the Beaverhead. The terrain is marked by prominent peaks such as Jumbo Mountain and Squaw Mtn, with a network of Pack Trails providing the primary access to the backcountry. Water resources are plentiful, including Ovis Lake and the Twin Lakes at the headwaters of Big Lake Creek. The presence of the Slag-a-melt Mine and Slag-a-melt Creek in the south suggests early mineral exploration in these remote drainages, while names like Sawmill Creek point to the historic timber and resource use that sustained local mountain economies.
