About this map

The Blackfeet Indian Reservation dominates this 1985 landscape, where the high plains meet the intricate drainages of the Two Medicine River and Birch Creek. This provisional survey illustrates a complex water management system, featuring an extensive Canal network and irrigation works that crisscross the terrain between Buffalo Ridge and Rocky Ridge. The presence of several Oil Field locations across the northern sections, particularly near Lookout Butte, points to the industrial energy development that has long been a significant part of the local economy on tribal lands.

Small river-side locales like Shields Crossing and Rock City appear along the winding waterways, providing specific points of reference for local historians. The map also records an Indefinite Boundary following the serpentine path of Birch Creek, separating Glacier and Pondera Counties and marking the edge of the reservation lands in a region defined by its deep coulees and distinct topographical ridges.
