1971 Map of Coburn Butte

About this map

The Fort Belknap Indian Reservation Boundary cuts through this north-central Montana landscape, marking a clear divide in the prairie terrain of Phillips County. This 1971 survey highlights the irrigation and ranching infrastructure critical to the region, including the winding path of the Coburn Ditch and the established Matador Ranch. The topographic detail reveals the prominence of Coburn Butte and the Judith River Ridge, which overlook a complex network of waterways like Little Warm Creek and Beaver Creek. The presence of Baker Cr and Bear Gulch indicates the drainage patterns that have shaped these grasslands for generations. Together, these features document a period of managed ranchlands and significant tribal boundaries during the early 1970s.
