The Sweet Grass Hills rise prominently along the Montana-Alberta border, featuring significant peaks like West Butte and East Butte. This mid-century landscape is defined by the development of the high plains, where the Great Northern railroad corridors fostered a string of settlements including Chester, Joplin, and Rudyard. The presence of numerous Oil and gas wells near Sunburst and Kevin points to the region's industrial heritage in the Kevin-Sunburst oil field. Large-scale water management projects are visible through the Tiber Reservoir on the Marias River and the Fresno Reservoir on the Milk River. To the east, the Rocky Boys Indian Reservation occupies the edge of the Lonesome Prairie, while the southern reaches follow the winding path of the Missouri River near Virgelle.
