2020 Map of Rocky Coulee SW

About this map

The Marias River carves a deep, winding course through the southern portion of this Hill County landscape, creating a complex series of bluffs and breaks. The surrounding plains are interrupted by significant drainage features such as Eightmile Coulee and Flat Coulee, which illustrate the erosion patterns typical of this Montana region. Human activity is defined by a sparse network of section-line roads and specific routes like Tiber Dam Rd and O'neil Dr. The map reflects the large-scale agricultural and ranching divisions of the Public Land Survey System, specifically within t29n r8e and t30n r8e, where the terrain transitions from open high ground to the sharp relief of the river valley.
