The Little Belt Mountains define the southwestern corner of this area, where the Lewis & Clark National Forest encompasses high ground like Roughlock Hill. The landscape transitions from these forested peaks into a network of drainages and coulees, including Martin Coulee and Big Coulee. This 2017 survey reveals a rugged geography marked by deep incisions like Buffalo Canyon, Dark Canyon, and Saager Canyon.
