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.

Losing elevations as you move from west to east and from south to north there is not quite a thousand feet of elevation change across the entire unit, with Southeast corner in the river bottom of the Missouri River being the lowest point. The bulk of the unit is very flat with little roll to the overall landscape. Gaining a little elevation and glassing for animals can be very effective.

Highway 212 is the main drag crossing the unit west to east. Closer to the western edge of the unit you will also find highway 63 moving north and south across the bulk of the unit. Other than access on the Missouri River which makes up the eastern and southern border these are the main access routes to the unit. There are countless county roads coming off of each of these drags, which will get you into every corner of the unit.

A mix of short and tall prairie grass for miles in all directions as well as countless species of wildflowers can be found in most areas of the unit that haven’t been turned for agricultural purposes. In the areas closest to the river you can expect to find much more timber which is primarily a mix of Cottonwood, American Elm, Green Ash, and Bur Oak as well as other small creek beds scattered across the unit.

There are a few scattered locally owned hotels and gas stations spread throughout the unit and along the major routes and the borders. Runnings is a sporting goods store located just outside of the unit in the northeast corner in the town of Mobridge. There are two established campgrounds in the unit one on the Northcentral part of the unit, the Little Moreau State Recreation Area, and the Camp Leslie Marrowbone Sioux which is in the southeast corner of the unit, along the banks of the Missouri River. North Eagle Butte in the Southwest corner of the unit is the largest town found in the unit and has all of the amenities you would expect to find in a small town - grocery stores, gas stations, a steakhouse, and even a small hospital if you run into an emergency.
