About this map

The Rocky Boys Indian Reservation dominates the center of this northern Montana landscape, where the terrain shifts from the high, distinctive profile of Square Butte down into a complex network of drainage systems. The survey captures the border region between Hill Co and Chouteau Co, documenting a watershed defined by the winding course of Big Sandy Creek and the seasonal flows of Sand Coulee.
