About this map

Little Porcupine Creek and Stellar Creek define the drainage patterns of this Rosebud County landscape as it appeared in the late 1960s. The terrain is marked by significant hydrological management, evidenced by the presence of the Hay Creek Reservoir, Corny Coulee Reservoir, and Black Coulee Reservoir. These man-made features suggest a ranching or agricultural economy reliant on captured runoff in a territory where seasonal water flow is critical.

In the southeast, the topography rises sharply toward the Schoolmarm Buttes, a prominent local landmark. Nearby, the Porcupine Lookout provides a strategic high point overlooking the complex network of draws including Wagon Box Coulee and the split channels of the North Prong Black Coulee and South Prong Black Coulee. The map detail captures the remote character of this Montana region before more modern infrastructure changes altered the landscape.
