Beaver Mountains in the Fishlake National Forest and the foothills take up most of the land in this unit which is partly BLM land. Interstate 15 is the western boundary and US89 is the eastern. Great genetics and bucks can be encountered in this popular unit. Hunting can be physically challenging here.

Much of the land 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. Though deer can be seen from main roads, some ideal vantage points are half a mile or more from roads. 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. The middle elevations grow Douglas firs, aspens, low browse plants, grass meadows, and sagebrush. The lower country is covered by 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 access high places and those include State Road 153, Fremont Canyon Road, and Forest Service Road 113. 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 serves much of the unit.

Beaver and Marysville have lodging, gas, groceries, and other supplies. Camping is permitted on most public land. There are several campsites on Highway 153 headed out of Beaver.
