2021 Map of Slaughter Reservoir

About this map

Slaughter Reservoir sits in the northeastern corner of this landscape, a prominent water feature in a high-plains terrain defined by complex drainages and rugged draws. This region, straddling the border between Crook County, Wyoming, and Butte County, South Dakota, is shaped by watercourses such as Hay Cr and the S Br Grummit Canyon Cr. The elevation rises toward Norgrain Hill in the west, while the eastern reaches are marked by more level stretches cut by the deep path of Headland Draw. Long-established ranching and rural access routes like Sourdough Rd and Horn Rd crisscross the section lines, reflecting the modern utility of these grazing lands. The map detail provides clear insight into how local geography dictates transit, with roads like Bentonite Rd following the natural contours of the northern hills.
