About this map

The Little Wolf Mountains and Sarpy Mountains dominate this high plains landscape along the border of Big Horn and Rosebud counties. This region is defined by an intricate drainage system where numerous coulees and prongs carve through the elevation, including Indian Coulee and its various branches like North Fork Indian Coulee and Williams Prong Indian Coulee. These features represent the complex hydrology of the western range, where seasonal water flow is critical to the local geography.

Named peaks and landmarks such as Chalky Point provide orientation points in a territory marked by significant elevation changes. Watercourses such as E Fork Sarpy Cr and Water Holes Cr illustrate the vital network of creeks that support the area's ecosystems. The mapping of Wood Gulch and Lynch Coulee further highlights the varied topography that has historically shaped land use and ranching boundaries in this part of Montana.
