Southeast of Richfield and west of Koosharem, this unit is known for producing the world record Spider Bull in 2008. This area has been managed for many years to produce trophy elk. Few tags are harder to draw than a Monroe mature bull permit.

Southeast of Richfield and west of Koosharem, this unit has terrain varying from high tundra in the north to sagebrush lowlands and pinyon/juniper forests in the south. Most canyons and basins above 8,000 feet have streams and lakes. Some steep, rocky canyons in the west are hard to reach. Hunters must hike or ride horses to reach remote country. Some private property is in the northern and central parts of the unit. Many peaks range from 8,500-10,000 feet above sea level. Monroe Peak and Glenwood Mountain are both higher than 11,000 feet.

High country has some alpine tundra and dense Engelmann spruce forests mingled with lodgepole pines. Middle-elevation terrain has Douglas fir, aspens, grass meadows and sagebrush. Low country has pinyon/juniper woods, grasses, oak brush, sagebrush and other browse. Elk get water from springs, small lakes and perennial streams.

Road access is good in this unit with numerous trails and roads. To reach the east end, take Greenwich Canyon and Koosharem Canyon roads which reach the center of the unit. Pole Canyon road and Monroe Mountain roads access the south end. Hunters can reach the west end of the unit by using the Dry Creek Road. Monroe Mountain Road runs north and south through most of the unit. Heavy rainfall or snow, which is likely during the late season, can make high roads slick and dangerous. The western boundaries are US Highway 89 and Interstate 70. State Route 24 and State Route 62 are the eastern boundaries of the unit.

Richfield has lodging, gas, groceries, and other supplies. Camping is permitted on most public land. There is one designated campground on the unit that is near Koosharem Reservoir. There is also a campground outside the unit near Otter Creek State Park.
