1968 Map of Nevada Mountain

About this map

The Continental Divide serpentines across this high-altitude landscape of the Helena National Forest, serving as the natural boundary between the Powell and Lewis and Clark counties. Dominating the topography is Nevada Mountain, a prominent peak that anchors a complex network of drainage systems. The map captures an era of resource extraction and transit through difficult terrain, evidenced by several mining operations including the Cyclone Mine near the headwaters of Poorman Creek. Connectivity across these ridges is maintained by a series of primitive routes, most notably the Helmville Trail and various jeep trails that follow the contours of the gulches. Waterways like Nevada Creek and Shingle Mill Creek carve deep into the landscape, reflecting the rugged hydrology of the northern Rockies in the late 1960s.
