Located on the eastern edge of the Black Hills, this relatively small unit is perfectly located in the transition areas of the prairie leading up to the higher elevations. This is an excellent habitat for mule deer and a growing population of whitetails. The unit is made up of entirely private land, so without prior arrangements do not plan on hunting this unit on a DIY-style hunt. Approximately two-thirds of the way up the unit, there is one major drainage running across from west to east with some of the most notable habitat in the unit.
There is virtually no public land in this relatively small unit on the edge of the Black Hills. With this, there is not much chatter in regard to this location.
