The Fort Peck Indian Reservation Boundary defines the western edge of this landscape, marking the transition between tribal lands and the open range of Valley County. In this rugged corner of Montana, the winding course of Porcupine Creek serves as a central drainage, flanked by several smaller geographical features like Enright Coulee and Hay Coulee. Industry leaves a distinct mark near the center of the sheet with a labeled Strip Mine, indicating the mineral extraction activity that often occurred alongside cattle ranching in this era. Other scattered water resources, including Middle Reservoir and Potter Spring, appear as critical landmarks in an otherwise arid and sparsely populated expanse of the northern plains.
