Radersburg occupies a small valley floor on the eastern edge of this 2017 survey, where residential streets like Johnson St and Mill Rd meet the surrounding ranchland of Broadwater County. The terrain to the west rises sharply into the Helena National Forest, a landscape defined by deeply incised drainages including Keating Gulch and Uncle Johnnys Gulch. This western sector is dotted with natural water sources such as Piedmont Spring and White Rock Spring, essential landmarks for the local cattle and mining industries that have historically shaped this region. To the northeast, the Limestone Hills overlook an intricate network of irrigation systems, most notably the Swede-Hollings Ditch and Dowdy Ditch, which redirect the waters of Crow Cr toward the lower fields. The map also identifies the NG Mta military training area and prominent peaks like Lone Mtn, providing a precise record of contemporary land use and topography.
