This unit located in the Northcentral part of the state along the banks of the Missouri River. This area is owned by the Cheyenne River Reservation, which is the fourth largest reservation in the lower 48. Spanning over 1.5 million acres, only a small portion of the unit has public access and what does exist is Walk-in properties. Hunting on the Walk-in ground will require a license through the normal state draw system, meanwhile the bulk of the hunting is managed by the reservation which conducts its own draw for opportunities to hunt big game. Overall there are few amenities found in this unit, and once you leave the major access routes there is little to no service found throughout.

The bulk of this unit is controlled by the Cheyenne River Reservation. The reservation conducts its own draws for hunting opportunities throughout the unit but hunters holding state issued tags can still hunt private lands and walk-in areas.
