West Desert, Vernon, Utah

The unit encompasses four distinct mountain ranges rising from broad desert basins: the Sheeprock Mountains (Black Crook Peak, 9,274 ft) form the central spine, with the Simpson Mountains, Keg Mountain, and surrounding bajadas filling the rest. Valley floors sit near 4,550 ft, and the terrain transitions from gentle sagebrush flats and rolling hills on the lower benches to steep, rocky canyon country on the mountain faces. Elevations where most deer are found range from roughly 6,500 to 8,000 ft on moderate to steep slopes. The unit drains into East Government Creek, Vernon Creek, Faust Creek, and South Pine Canyon.

Primary highway access is SR-36, which runs along the eastern boundary through Vernon and connects south to US-6 at Nephi; US-6 forms the southern boundary near Delta. SR-174 (Brush Highway) is a paved two-lane road along the southwest boundary. The Pony Express Road (an unpaved BLM two-track following the historic Pony Express/Overland Stage route) defines the northern boundary and provides interior access to Simpson Springs, which has a historic Pony Express station and BLM campground. BLM roads branch south from the Pony Express Road and north from SR-174, providing dispersed vehicle access; most require high-clearance 2WD or 4WD. Vernon Creek canyon roads are passable by sedan partway, requiring high clearance deeper in. Little Sahara Recreation Area (BLM) in the southeast is accessible by ATV and OHV on designated routes. The Department of Defense (Dugway Proving Ground) borders the unit northwest corner and is closed to public entry; the unit boundary excludes that installation.

The dominant cover type at lower elevations is Great Basin sagebrush scrub with scattered greasewood and bitterbrush, transitioning to pinyon-juniper woodland on the mountain mid-slopes. Cheatgrass and annual grass invasion is an ongoing management concern throughout, and PJ encroachment into sagebrush habitat has reduced forage quality on portions of the winter range. Riparian draws (Vernon Creek, Faust Creek) support perennial grasses, forbs, and shrub cover. The Little Sahara Recreation Area in the southeastern corner is dominated by active sand dunes with sparse shrub cover. There is no significant aspen, ponderosa pine, or spruce-fir component; this is a cold desert and semi-arid shrub-steppe system.

Mule deer are the primary big game species managed in this boundary; the 2025 post-season population estimate is approximately 2,600 deer, against a management objective of 2,200. The Sheeprock Mountains hold the highest deer concentrations; larger bucks frequently use the sagebrush flats and rolling hills below the ridgelines rather than the alpine core. Keg Mountain supports lower deer densities. Pronghorn are present in the broader West Desert landscape but have separate named hunt units (Riverbed, Rush Valley, Snake Valley) that do not correspond to the Vernon boundary. The unit sits in CWD surveillance territory; the adjacent Oquirrh/Tintic unit is CWD positive at low prevalence, and UDWR conducts rotational surveillance sampling in the West Desert complex.

All-method success rate of 75.8% is the 2024 aggregate (185 harvested / 244 hunters afield). 2026 approved quota is 254; 2025 season issued 230 total tags. Drain corrected to East Government Creek (not West Government Creek) per RAC watershed data.
