As the most northwestern unit in the state, it has a unique terrain. It is a dramatic mix of prairie as well as abrupt elevation change throughout. There are patches of dense timber in the higher elevations and miles of prairie grass and CRP in the rest of the unit. This unit covers over 800,000 acres in total with just over 150,000 acres of public land. This is a mix of walk-in access as well as different sections of state property throughout. Overall this is a rather remote unit with few amenities. There is a healthy population of both whitetail and mule deer in this unit. This unit offers an excellent chance at a successful hunt for hunters who are willing to put in the miles both on their boots as well as in the vehicle.

With scattered sections of public access, there are few hunters headed to this unit without a plan around hunting some private property.

Being located in the northwestern corner of the state the terrain here is more broken than much of the state outside of the Black Hills. There are multiple hills protruding out of the prairie often gaining as much as 500 feet in elevation. There are countless creek beds and small streams scattered across the unit, but no major river or drainages. There are scattered areas of agriculture throughout the unit but overall there is not much as a whole in the unit.

State Highway 20 runs east to west and is the only state highway that runs through the unit. Outside of this all other access in the unit would be from the many county highways and roads. Harding Road is the main drag in the southern half of the unit. North Camp Crook as well as South Cave Hills both north of Highway 20 run towards the northern more remote sections of the unit. There are many acres of walk-in access across the unit as well as scattered other public hunting across the unit.

In the higher elevations of the unit, you will find a mix of pine and different conifer trees throughout, as you move to the lower elevations you will find a mix of short and tall prairie grass. Outside of the prairie, there is some agricultural land.

On the eastern border of the unit close to halfway up Highway 85 is the town of Buffalo, South Dakota, although only 330 people it is the county seat of Harding County and is the major hub of the area. There is one locally owned hotel as well as a gas station. Overall there are few amenities across the entire unit. Picnic Spring Campground is one of the only campgrounds and can be located towards the northern border of the unit a few miles outside of Ludlow South Dakota.
