1966 Map of Diamond City

USGS Topo · Published 1970

About this map

Diamond City (Site) serves as the focal point of this mid-century topographic record of the Big Belt Mountains, situated within the Helena National Forest. The landscape is deeply incised by a network of drainages famously tied to the region's mining heritage, most notably Confederate Gulch and White Gulch. While the city itself is noted as a site, the map preserves the locations of early local infrastructure such as the Johnson Sch and a small Cem near the creek. Evidence of resource extraction is scattered across the slopes, from the Miller Mine in the north to various unnamed Mines and a Prospect along Boulder Creek. The terrain is navigated by a system of Jeep Trails and Pack Trails, illustrating how this part of Broadwater County was accessed for both industry and forest management before modern road development reached deeper into the gulches.
