About this map

Placer and lode mining claims define the landscape of this Broadwater County region in the mid-1980s, particularly around the Giant Hill Prospects and the Limestone Hills. The map shows a transition from the wooded slopes of the Helena National Forest to more arid, gulch-cut terrain further east. Remote settlements like Hassel and Mc Mullan appear alongside evidence of heavy industry, including numerous Mine Shafts, Tailings, and Adits scattered near Ribedeau Gulch and Badger Gulch.

Hydrology is vital to the area's history, with labels marking essential water sources like Elkhorn Spring, Cold Springs, and Hunters Spring. The terrain is marked by prominent elevations such as Big Mountain and Glendale Butte, while several 4WD tracks trace the routes through the West Fork Indian Creek drainage, suggesting a landscape shaped by persistent prospecting and resource extraction long after the initial booms of the century.
