2014 Map of Thoeny Hills East

About this map

Thoeny Hills and the rugged northern drainage of the Big Dry Creek basin define this high-plains landscape along the international border in Phillips County. The terrain is deeply incised by a network of drainage features known locally as coulees, which channel seasonal runoff from the Montana uplands toward the south. Notable geographic landmarks include the appropriately named Turkey Track Coulee and Dead Horse Coulee, names that suggest the historic ranching and livestock history of this borderland region. In the northern reaches, the map records the proximity of the United States and Canada border, an area where the transition from the rolling hills to the prairie floor is marked by ephemeral waterways like Steelman Coulee and Sand Cr. Remote ranch roads such as N Frenchman Rd provide the only significant infrastructure through this sparsely populated territory.
