Mule Deer Hunting in Unit 20

Where to Find Mule Deer in Unit 20

Unit 20 mule deer range across juniper scrub and rocky hillsides in south-central New Mexico.

Juniper-Oak Hillsides

Rocky hillsides covered in juniper and scrub oak are the primary deer habitat. Bucks bed on north-facing slopes during heat and feed on south-facing openings at dawn and dusk.

Desert Grassland Edges

Lower elevation grassland adjacent to juniper draws deer during early season. Glass open terrain from elevated positions at first and last light.

Pinon-Juniper Drainages

Narrow drainage corridors with denser pinon-juniper serve as travel routes and water sources. Scout active drainages for fresh deer sign pre-season.

How to Hunt Mule Deer in Unit 20

Unit 20 mule deer hunting requires efficient glassing of rugged juniper hillsides.

Hillside Glassing

Set up on elevated positions overlooking juniper hillsides before first light. Glass systematically through rocks and brush where bucks bed.

Rut Hunting

November rut pushes bucks out of heavy cover. Glass grassland edges and saddles connecting drainages for rutting bucks moving between does. Grunts and bleats can work during active rut phases.

Pronghorn Hunting in Unit 20

Unit 20 covers central New Mexico from the Rio Grande east across the plains. Open grassland and juniper savanna from 4,500 to 5,500 feet hold scattered pronghorn herds. 109 tags against 635 applicants over three cycles makes this a moderately competitive draw, with most tags going through the A-PLUS program.

Where to Find Pronghorn in Unit 20

Unit 20 is primarily private-ranch country; A-PLUS tags specify your ranch.

Central Grasslands

Shortgrass flats between Socorro and the Estancia basin hold the densest herds.

Juniper Savanna Edges

Juniper/grassland transitions offer shade and bedding; bucks cruise these edges mid-morning.

Stock Tank Circuits

Reliable windmill tanks pattern herds during dry seasons.

How to Hunt Unit 20 Pronghorn

Classic southwest pronghorn tactics apply.

Glass from Elevation

Use ranch two-tracks to reach low rises. Glass hard for 30–45 minutes at each stop before moving.

Stalk in Washes

Ephemeral washes and cuts are the only reliable stalking cover. Plan routes that keep you below the horizon line.

Decoy Tactics

During rut window, a buck decoy draws aggressive herd bulls.

Rocky Mountain Bighorn Sheep Hunting in Unit 20

Unit 20 covers the southwestern portion of New Mexico's Gila region — extending from the Burro Mountains toward the Arizona border in Grant and Hidalgo counties. This unit holds a bighorn sheep herd in terrain transitioning between Madrean sky island habitat and Chihuahuan Desert. Rocky escarpments and desert grassland create unique sheep hunting conditions. Tags are extremely limited and draw odds are very low.

Where to Find Bighorn Sheep in Unit 20

Unit 20 sheep habitat is anchored by the rocky ranges in the unit — particularly the Burro Mountains and adjacent rocky terrain. Sheep use cliff bands and rocky canyon walls for escape cover while ranging into adjacent desert grassland for feeding.

Burro Mountains Rocky Terrain

The volcanic intrusive rock formations and ridge systems in the Burro Mountains provide the cliff face habitat that anchors the Unit 20 sheep herd. Focus on the escarpment faces and rocky saddles along the main range crest.

Canyon Systems

Drainages cutting through the rocky terrain concentrate sheep movement. Glass from elevated positions at canyon heads and junctions — particularly in morning when rams are moving from overnight bedding sites to feeding areas.

Desert-Rocky Transition

The interface between the rocky mountain terrain and the surrounding desert grassland is where sheep feed. Early morning finds animals on these open slopes before retreating to cliff cover during midday heat.

How to Hunt Bighorn Sheep in Unit 20

Unit 20 sheep hunting combines the challenges of high-country sheep hunting with desert heat and water scarcity. Thorough pre-season scouting and heat management are critical.

Water Planning

Water sources in the southwest New Mexico desert are scarce and seasonal. Know the locations of every permanent water source in your hunting area before the season. Sheep require water regularly — water is a key aggregation tool for locating animals.

Early Season Heat Management

Early sheep seasons can overlap with warm desert conditions. Plan hunting activity for the first two hours after sunrise and the last hour before sunset. Midday heat in October can still reach 80–90°F in the lower desert terrain of this unit.

Glassing the Rocky Faces

Establish glassing positions on high ground before first light and systematically work the cliff faces and rocky ridgelines across the canyon. Bighorn rams are often stationary for extended periods on bedding ledges — patient glassing reveals animals that active searching would miss.

Frequently Asked Questions

What public land is available in Unit 20?

BLM public land and Gila National Forest parcels provide public access in Unit 20. Identify specific sections on BLM or USFS maps before your hunt.

Does Unit 20 include El Malpais?

Portions of the El Malpais National Monument and Conservation Area fall within or adjacent to Unit 20. Monument lands have separate hunting regulations — confirm boundaries before hunting.

Is Unit 20 DIY-friendly?

Yes. The Cibola NF and BLM holdings provide extensive DIY public access.

Do I need landowner permission for Unit 20 pronghorn hunts?

Most tags are A-PLUS and tied to specific ranches, so access is guaranteed through that program. Non-A-PLUS tags require contacting private landowners directly since public land is limited.

Does Unit 20 have Rocky Mountain bighorn or desert bighorn sheep?

NMDGF classifies the Unit 20 herd as Rocky Mountain bighorn sheep (Ovis canadensis canadensis). However, the habitat in southwestern New Mexico has desert character. Confirm the current NMDGF hunt code classification as subspecies designations can affect application eligibility.
