2017 Map of Iron Spring

About this map

Iron Spring sits at the heart of this landscape, marking a vital water source in the high plains of southern Montana. This survey documents the intersection of Treasure County and Big Horn County, where the terrain is defined by a dense network of coulees that drain toward the Sarpy Cr valley. To the south, the Red Hills rise above the drainage of Cottonwood Cr, illustrating the complex topography that historically dictated the routes of local ranch roads like Iron Springs Rd. The map reveals the intricate drainage patterns of the region, featuring named landmarks such as Coxs Coulee, Willoughby Coulee, and Schrites Coulee. These geographic features and specific spring locations, including several numbered water sources, provide essential context for understanding land use and livestock movement in this part of the Big Horn Basin vicinity during the early twenty-first century.
