Opheim Hills and the Dahl Hills characterize this high-plains landscape in northeastern Montana, where the terrain is deeply etched by a complex drainage network. The area is defined by numerous coulees, such as Coyote Coulee, Furlong Coulee, and Combs Coulee, which channel water toward larger systems like Willow Creek and the West Fork Porcupine Creek.
