2021 Map of Oat Creek

About this map

The Buffalo Gap National Grassland and Oglala National Grassland meet at a unique tri-state border junction on this survey, where the rangelands of Niobrara County, Wyoming, Fall River County, South Dakota, and Sioux County, Nebraska, converge. This sparsely populated prairie landscape is defined by an intricate network of seasonal drainages and draws that carve through the high plains. The water systems are divided between systems like Middle Fork Alkali Cr and S Fork Alkali Cr in the northeast, and the southern reaches of Oat Creek and Eagle Draw. Aside from the presence of Boner Rd in the Wyoming portion, the map reveals a terrain primarily dedicated to public grazing lands and open range, offering a clear view of the complex legal and geographic boundaries that define the American West's high plains borderlands.
