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.
