This smaller unit is found in the northeast portion of the state and just southeast of Gillette. There are a few areas of public lands including the Thunder Basin National Grassland, BLM land, and state land that can be hunted, but pressure is high in these areas due to minimal public lands available.

Antelope populations in the Sheridan Region are managed recreationally so most units are designed to give hunters a lot of opportunities. Access to private lands are difficult, but hunters willing to wait until after opening day and weekend can find easier access to private land.

This area is mainly lowlands containing big flats with a little terrain consisting of small benches mixed with ravines and small drainages. Most of the terrain here has clay bluffs and ridges found throughout the unit. There are a lot of areas to find elevation and glass for long distances.

Vegetation like sage and grass and an occasional pinyon or juniper tree grow here. There are a few areas of pine located throughout the center of the unit.

Getting into this unit can be difficult due to private lands and the several coal-mining operations that are going on in this area. Hunters can hunt on the Thunder Basin National Grassland, but hunting pressure is high due to the lack of public land on the unit. Travel can become difficult in the rain and hunters should be prepared with chains.

Camping locations can be hard to find in the unit. Thunder Basin National Grassland contains a small number of areas of dispersed camping areas. Lodging, fuel and grocery options can be found on the north end of the unit in communities of Moorcroft and Gillette.
