About this map

Jumbo Mountain dominates the northwestern terrain of this high-elevation landscape on the Montana-Idaho border, where a complex network of alpine drainage basins feeds the headwaters of numerous creeks. The geography is defined by its water systems, notably the Twin Lakes which serve as a focal point for recreation and forest management. Near these lakes, the Twin Lakes Campground and the Twin Lakes Forest Service station indicate the area's role in public land administration and seasonal outdoor use.

Evidence of historical resource extraction appears in the southeastern corner at the Slag-A-Melt Mine, situated near the oddly named Slag-a-melt Creek. This industrial footprint contrasts with the surrounding wilderness, where named waterways like Big Lake Creek, Sawmill Creek, and Big Swamp Creek carve through the high country. Primitive access is maintained via Twin Lakes Rd, providing a trace of the infrastructure required to navigate this remote portion of Beaverhead County.
