Unit 42
MESA/GARFIELD
Colorado River canyon country with rolling forested ridges, scattered reservoirs, and significant terrain complexity.
Hunter's Brief
Unit 42 spans the Mesa-Garfield County border between the Colorado River and the Roaring Fork drainage, offering a mix of forested ridges and open parks at mid-to-high elevation. The terrain is substantial and broken—rolling country with scattered timber, open meadows like Elk Park and Coyote Park, and multiple drainages cutting through. Water availability is patchy despite numerous reservoirs and ditches; seasonal creeks are primary reliable sources. Over 700 miles of roads provide reasonable access, though the unit's complexity and size mean pressure concentrates along main corridors. Expect to work for solitude and elk here.

Terrain Deep Dive
Landmarks & Navigation
Long Point and Houston Mountain anchor the high country for distant glassing; Coal Ridge and Fire Ridge form the backbone dividing east-west drainage. The Slides present a notable landmark in the western terrain. Key parks—Elk Park, Coyote Park, Tepee Park—serve as navigation reference points and likely elk staging areas.
Battlement Creek and Wallace Creek drainages mark major travel corridors through the unit; Snowslide Creek and Lava Creek provide additional drainage-based navigation. These creeks and ridges work together as a navigation grid on the ground.
Elevation & Habitat
Terrain climbs from around 4,800 feet along the Colorado River bottoms through rolling sagebrush and aspen foothills into dense lodgepole and spruce-fir country above 9,000 feet. Mid-elevation zone—roughly 7,000 to 9,000 feet—supports the bulk of huntable country: ponderosa and Douglas-fir stands mixed with open parks and meadows where elk concentrate. Upper elevations feature high parks and timbered benches; lower elevations give way to canyon country along the Colorado and its tributaries.
The elevation gradient is moderate but the mix of forest, parks, and drainage complexity creates diverse habitat zones within short distances.
Access & Pressure
Over 700 miles of roads create a connected network without being heavily developed. Road density is fair but unevenly distributed; main drainage bottoms and high valleys have road access while side ridges and benches are road-free. Access pressure likely concentrates along Battlement Creek drainage and main ridge roads; hunters willing to hike away from road-heads will find more open country.
The unit's 8.2 complexity score reflects significant terrain—plenty of room to move and escape pressure if you're willing to work. Battlement Mesa area functions as a logical staging point.
Boundaries & Context
Unit 42 occupies the western slopes of the Elk Mountains drainage divide, anchored on the north by the Colorado River and bounded on three sides by creek divides—South Canyon and Baldy Creek to the east, Divide Creek-Muddy Creek and Plateau Creek divides to the south, and the Colorado River to the west. The unit encompasses rolling country at the transition between the Roan Plateau and high country to the east, spanning from low-elevation river corridors up to alpine ridges. Geography here is defined by fingers of drainage and scattered tablelands that funnel elk movement and create distinct hunting territories.
Water & Drainages
Perennial drainages are concentrated: Battlement Creek, Wallace Creek, and their forks hold water through the season, with Snowslide and Lava Creek providing supplementary sources. Mosquito Lake and Watson Reservoir offer reliable water access but aren't the primary hunting focal points. Numerous ditches (Highline, West Divide, Porter, and others) service agricultural lands but are inconsistent for hunter use.
Dry Creek lives up to its name. Spring sources exist—Uncle Bob Spring and South Canyon Hot Springs noted—but water scarcity badges the unit; dry camping and careful route planning around known drainages are essential strategies.
Hunting Strategy
Elk are the primary target, using the mid-elevation parks and ridge transitions as core habitat. Early season hunting focuses on high parks and timber; rifle season pressure pushes elk into deeper drainages and upper timber. Mule deer occupy similar elevation bands but favor more open park transitions; whitetails concentrate in riparian bottomland.
Pronghorn use the open flats and lower parks, though limited pronghorn range in this unit. Moose inhabit willow areas along main creeks, particularly Battlement Creek drainage. Mountain lion and bear are present—lions hunt ridges and parks, bears work berry patches above 8,500 feet.
The unit rewards hunters who use topography to intercept elk movement between low and high country while water sources become critical decision points during dry periods.
