This entire unit, located in the north central part of the state on the banks of the Missouri River, is owned by the Cheyenne River Reservation, which is the fourth largest reservation in the lower 48. This unit has virtually no public access and what does exist is walk-in ground primarily found in the most northern portion of the unit. 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. There are few amenities found in this unit, and once you leave the major access routes, there is little to no service found throughout.

There are good populations of whitetail found throughout the unit with pockets of mule deer. The overall vastness of this unit allows for some above average bucks of both species to be taken each year.
