The Tongue River and its sprawling Tongue River Reservoir define the geography of this Big Horn County region, where the water's edge meets the high plains of southern Montana. Near the Wyoming border, the small settlement of Decker serves as a local hub, anchored by the Decker Post Office and connected to the wider territory by Otter Rd and County Rd 76. The landscape is a complex drainage system, with numerous tributaries such as Squirrel Creek, Badger Creek, and Pearson Creek feeding into the main river valley.
