2017 Map of White Horse Coulee

About this map

Larb Hills anchor the southwestern corner of this high-plains landscape in Valley and Phillips Counties. The terrain is defined by an intricate network of drainage channels, or coulees, including the prominent White Horse Coulee and Black Coulee. These features represent the characteristic erosional topography of the Montana badlands, where water management is critical for ranching, evidenced by the presence of Bearcracks Reservoir. Local navigation is facilitated by rural routes such as Triple Crossing Rd and Content Rd, which traverse the open range between drainage systems like Larb Cr and Sage Cr. A notable geological or surveyor's reference known as The Sag sits near Badland Coulee, providing a specific landmark for those studying the physical history of the region. The map captures the quiet, sparsely populated nature of the eastern Montana prairie at the start of the twenty-first century.
