About this map

The Two Medicine River carves a deep, winding path through this portion of the Blackfeet Indian Reservation, creating a landscape defined by dramatic elevation changes and seasonal water flow. Surveyed in the late 1960s, the terrain is dotted with Numerous small kettle ponds and springs, suggesting a glacial history that has shaped the drainage patterns of the South Fork and Deep Creek.

Signs of resource exploration appear in the western reaches, marked by an Oil Well and a Drill Hole, highlighting the intersection of industrial interest and tribal land management. The prominence of Big Rock serves as a central landmark amidst the prairie and coulees, while the courses of Elk Creek and Depot Creek further illustrate the intricate hydrologic network that supported grazing and movement across this high-plains environment during the mid-20th century.
