About this map

The Continental Divide anchors this high-elevation Montana landscape, tracing the border between Powell and Lewis and Clark counties. Steep ridges and deep gulches define the area, where the headwaters of Ophir Creek and Threemile Creek drain away from the peaks of Black Mountain and Illinois Ridge. This 1989 provisional survey highlights a landscape heavily marked by mineral exploration and extraction along the slopes, particularly near Blackfoot City.

Evidence of historical mining is everywhere, from the Victory Mine and various Mine Shaft locations to a high density of Prospect and Adit labels scattered through the drainages. The presence of Lost Cabin and a network of Pack Trail and Pack 4WD routes suggests a remote working landscape where topography dictated both travel and industry. The map's detailed hydrological features, including Georgia Creek and Eureka Gulch, provide a clear picture of the water-rich terrain that supported these high-country ventures.
