Unit 84
CUSTER/FREMONT/HUERFANO/PUEBLO
Forested foothills and plateau country straddling the Wet Mountains with moderate elevation and scattered water sources.
Hunter's Brief
GMU 84 covers the transition zone between the plains and high mountains, centered on the Wet Mountains and surrounding plateaus. Terrain ranges from lower sagebrush benches to timbered ridges with scattered parks and meadows. Access is solid with a connected road network, though the moderate complexity means some country stays quieter than others. Limited water requires planning, but reliable springs and creeks exist in key drainages. Elk, deer, and pronghorn all inhabit different elevation zones throughout the unit.

Terrain Deep Dive
Landmarks & Navigation
The Wet Mountains form the unit's backbone, with Saint Charles Peak, Mount Tempest, and Antelope Butte providing natural glassing platforms and navigational references. Liberty Point and Dome Rock offer additional vantage points along key ridges. Several divides—Wixson, Greenhill, and Bigelow—mark terrain transitions useful for planning movement between drainages.
Apache Falls and the various parks create landmarks hunters can identify from distance, helping with orientation in country that can feel expansive and complex.
Elevation & Habitat
The unit spans from mid-elevation valleys near 4,600 feet to alpine terrain above 12,000 feet, with most productive hunting in the 6,500 to 9,500-foot band. Lower elevations support ponderosa and piñon-juniper slopes, transitioning to mixed conifer forests at mid-elevations, with spruce-fir becoming dominant on higher slopes. Robinson Plateau, DeWeese Plateau, and the Rosita Hills form key ridgeline features, while scattered parks and meadows—Lion Park, Soldier Park, Antelope Park—provide natural openings.
This varied topography creates distinct habitat zones suitable for both high-country elk and lower-elevation mule deer.
Access & Pressure
The unit's connected road network—over 2,300 miles of roads—provides excellent access from surrounding communities and highways. This accessibility brings pressure, particularly on opening weekends and during peak seasons. However, the moderate topographic complexity means that large sections away from main drainages receive lighter pressure.
Parking areas and trailheads concentrate around the more accessible parks and reservoirs, creating opportunity to find quieter country by moving away from these main attractions.
Boundaries & Context
GMU 84 spans portions of Custer, Fremont, Herfano, and Pueblo counties in south-central Colorado. The unit's boundaries run along U.S. 50 on the north, I-25 and Colorado 1 on the east, Colorado 69 on the south, and Colorado 96 and 67 on the west. This positions the unit as a major stepping stone between the Front Range foothills and the higher San Isabel wilderness country, with several small towns (Rosita, Gardner, Beulah) providing services and staging areas.
Water & Drainages
Water is limited but strategically available. Major creeks include Sheep Creek, Bear Creek, and several smaller drainages that flow through the valleys. Multiple springs dot the higher elevations—Rooster Spring, Troyer Spring, Sheep Creek Spring, and others—though seasonal reliability varies.
Several reservoirs (Saint Charles Reservoir, Freeland Reservoir, Portland Reservoir) and natural lakes (Silver Park, Blue Lakes) provide reliable water sources. Hunters must plan water strategy carefully in lower-elevation country, but reliable sources exist in most major drainages.
Hunting Strategy
Elk typically occupy the higher mixed-conifer country in early season, moving to spruce-fir above 9,000 feet during rifle season. Mule deer and white-tailed deer spread throughout the unit across elevation bands. Pronghorn occupy the lower plateau country and parks.
Mountain lion and bear inhabit the timbered slopes. Start higher-elevation glassing in early season when elk are on summer range; focus on Antelope Butte, Mount Tempest, and ridgeline parks. As pressure increases, work the middle drainages where water sources concentrate elk movement.
Lower elevations are more productive later in season and during general deer season.
