This unit is north of Rawlins and southwest of Casper, and also includes the North Platte River, Pathfinder Reservoir and Ferris Wilderness Study Area. There is a lot of BLM land here that mule deer and some whitetails live on.

The Ferris WSA is steep and rugged with high ridges and deep canyons. Ferris Peak is the highest point in the Great Divide Basin at 10,037 feet and rises some 3,000 feet from the valley floor. Notable landmarks are Independence Rock, Sentinel Rocks, Seminoe Canyon, and sand dunes close to Bear Mountain.

There is a lot of good hunting in the Ferris Wilderness Area. Motorized vehicles are not allowed here. The Morgan Creek Wildlife Habitat Management Area also has a lot of land and has a stable herd of mule deer. Carbon County walk in area can be found a few miles south of Muddy Gap near Muddy Creek. County, BLM and secondary roads have a good road system here. Rain can close down travel on dirt roads, so bring four-wheel-drive vehicles. Hikes here can be long and rough so be in shape.

Ferris Mountain has big stands of Douglas fir and aspen. The North Platte River goes near the eastern edge and supports willow, cottonwood and lush grasses. The two major reservoirs here are Pathfinder and Semino.

Improved campsites can be found in Semino State Park. Miracle Mile, and BLM land has dispersed camping. Casper in the north and Rawlins in the south have a big selection of lodging and restaurants. Both communities have medical facilities and 24/7 gas stations.
