2020 Map of Black Spring

About this map

Indian Coulee and its associated Indian Coulee Spring anchor the southern reaches of this landscape in the Muddy District of Montana. The terrain is defined by a dense network of drainages and coulees that feed into Rosebud Cr, revealing the complex hydrology of the Big Horn and Rosebud county line. Vital water sources like Black Spring and Lynch Spring are intermittent but significant landmarks in this arid environment, often serving as the primary naming conventions for the surrounding landforms. The northern half of the survey is dominated by the multi-branched Cottonwood Creek system, including Little Cottonwood Cr, the N Fork Cottonwood Cr, and the S Fork Cottonwood Cr. This modern survey illustrates how township and range lines like t1s r40e continue to organize this sparsely settled ranching and grazing country.
