2020 Map of Forty Creek

About this map

Mizpah Cr winds through this section of Custer County, defining a drainage network that sustains the ranching landscape of eastern Montana. This 2020 survey illustrates the complex hydrology of the region, where numerous named tributaries such as Timothy Cr, Doat Cr, and Pinto Cr feed into the larger creek systems. The terrain is characterized by the branching coulees and draws of the high plains, most notably Dawson Coulee in the southwest. Land management and historical surveying are evident through the established township lines of t4n r51e and t4n r52e, reflecting the orderly grid imposed on the undulating prairie. Water remains the central feature of this environment, with labels like Windmill Cr and Double Corral Cr suggesting the practical human relationship with this semi-arid geography.
