The divide between Hill Co Chouteau Co marks the central boundary of this high plains landscape, defined by the erosion patterns of the northern Montana prairie. Deep drainage channels known as coulees carve through the terrain, notably the namesake Fourteenmile Coulee and Sixmile Coulee. These features represent the characteristic geological weathering of the region, where seasonal runoff creates significant topographical relief in an otherwise expansive grassland.
