Beaver Mountains in the Fishlake National Forest and the foothills take up most of the land in this unit which is partly BLM land. SR 130 is the western boundary with US 89 and Interstate 15 as the eastern boundary.

Bears seem to be equally distributed across the unit. Most seem to be in a color phase with very little black coats being found.

The majority of the land in this unit is steep and rugged. Most canyons have small creeks that run their length and have maintained hiking or horseback trails, some of which have high trailheads. Most canyons are deep. Glassing into roadless areas is possible with little physical effort, but much of the unit is so densely timbered that good vantage points are scarce. Private property blocks access in some areas, but short hikes can get a hunter almost anywhere. The Twitchell Fire in 2010 burned 45,000 acres, opening up parts of the north end that were hard to glass before the fire. Some of the highest peaks in the unit are above timberline.

Dense Engelmann spruces mingle with ponderosa pines and firs in the high country. Some alpine tundra is on the high peaks and basins. Douglas firs, aspens, low browse plants, grass meadows and sagebrush grow at middle elevations. The low country is covered with pinyon/juniper woods, sagebrush, oak brush, grasses, and various browse plants such as serviceberry and chokecherry. Water sources are spread throughout the unit with a lot of springs, small lakes, and perennial streams.

Some well-maintained roads including State Road 153, Fremont Canyon Road, and Forest Service Road 113, provide access to some higher elevations. Several roads are maintained through summer and fall. Snow or heavy rainfall can make some roads impassable. A great system of maintained trails allows hikers and horseback riders to reach remote areas. An extensive ATV trail system also serves much of the unit.

Beaver and Marysville have lodging, gas, groceries, and other supplies. Camping is permitted on most public land throughout the unit.
