Sun Prairie Flats dominates the central portion of this Phillips County landscape, characterized by broad expanses and drainage systems that define the regional geography. The terrain is marked by significant topographical depressions, most notably The Big Sag to the west and the eponymous Sheep Coulee which transitions into North Fork Sheep Coulee and South Fork Sheep Coulee. These features illustrate the erosion patterns typical of the Montana plains, where seasonal waterways like Flat Creek and Sage Creek have carved distinct paths through the high prairie.
