This unit is located in the southwestern portion of the state southeast of Rapid City, which is the largest city in the area. There are small townships down US Hwy 79 on the western side of the unit. The unit is primarily private land with the exception of two large sections of public land. One is a section of the Buffalo Grassland of over 16,000 acres and the other is a section of the Nebraska National Forest which is a little over 27,000 acres. The Cheyenne River makes up the bulk of the eastern border between this and three other major drainages the Rapid, Battle, and Spring Creek that stretch from east to west across the unit.

This unit has great antelope populations and a decent amount of public lands to chase them on. Hunters may still run into access issues with private lands in some areas, though, and GOHUNT maps is highly recommended to help navigate through these.
