The Sacagawea River winds across this Fergus County landscape, defining the local drainage patterns in the mid-1980s. The terrain is dominated by prominent landforms such as Griffee Ridge and a series of deep ravines, including Griffee Coulee, Dexter Coulee, and Fargo Coulee. This provisional map focuses on a largely undeveloped area where water resources are vital, indicated by the presence of Smith Creek and isolated Water Well locations. The absence of significant towns or highway networks suggests a region primarily dedicated to rangeland or open country, where the natural topography dictates movement and land use.
