Stretching from the southwest corner of the Great Salt Lake south to the Sevier Desert near Delta, this unit features Skull Valley and other valleys full of sagebrush and other low plants, which are ideal for pronghorn antelope, as well as foothills and several mountain ranges.

Though arid desert, this unit still has plenty of water and stretches from the southwestern corner of the Great Salt Lake south through Skull Valley to the Sevier Desert near Delta. Several small, isolated mountain ranges jut from the valley floor throughout the unit. Lowlands are mostly wide desert valleys. Most antelope will be found on the benches between these ranges and lowlands.

Ther is good road access to most of the unit. Dirt roads are rough, so make sure to carry spare tires and tools. Wet weather makes some roads nearly impassable. Most land is managed by the BLM, with the rest being controlled by the U.S. Army or private.

Low elevations consist mainly of grasses, rabbitbrush, sagebrush and scattered stands of pinyon/juniper. High sagebrush grows along creeks and on the shady sides of ridges. Farmlands dot many of the valley floors. Middle elevations and high elevations have pinyon/juniper and sagebrush with scattered stands of curl-leaf mahogany and white pine.

Several Forest Service and BLM campgrounds are south and west of Vernon. Most camping in the western part is along dirt roads. BLM campgrounds at Lone Rock, Horseshoe Knolls, and Whiterocks.
