About this map

Big Sandy and the surrounding plains of north-central Montana appear in this 1984 study, defined by an intricate network of coulees draining toward the Marias River and the Missouri River. The landscape is dominated by dry-land drainage features such as Sixmile Coulee, Fourteenmile Coulee, and Twelvemile Coulee, which carve through the high terrain between the major river valleys. The Burlington Northern railroad corridor serves as the primary industrial artery, linking settlements like Verona and Kenilworth to the regional trade network.

The eastern portion of the map includes a section of the Rocky Boys Indian Reservation and the landmark Box Elder, while the southern border traces the Missouri River through the Coal Banks Landing State Rec Area. Notable topographic elevations include Black Butte and Discovery Butte, which stand as significant landmarks for those tracing family history or early ranching boundaries in Chouteau, Hill, and Liberty Counties. The presence of Lonesome Lake provides a rare perennial water feature in this arid region of the High Plains.
