Overview
Unit 21A is the forested sub-unit of GMU 21 — officially 'that northwest portion of GMU 21 that lies within the Gila National Forest.' On the ground that means a long north–south strip of the Black Range's east slope, from the Alamosa Creek/Dusty country in the north down past NM 59, Kingston, and Emory Pass to the Grant–Sierra county line, with the Continental Divide along the crest as its western edge and the forest boundary above Chloride, Winston, and Hillsboro as its eastern edge. The core is the eastern half of the Aldo Leopold Wilderness — some of the most remote, rugged country in New Mexico — nearly all of which burned in the 2022 Black Fire. This is a genuine backcountry elk unit: the Black Range herd runs lower density than the famous central Gila units, so tags draw easier, but the roadless canyons hold mature bulls for hunters who pack in. Mule deer, black bear, and cougar round out a hunt that is defined by steep drainages, burn mosaic, and a near-total absence of roads. Expect a physical, lonely hunt and plan around post-fire trail conditions.
Terrain
The steep east slope of the Black Range: long ridge-and-canyon systems falling thousands of feet from the crest (topping out at McKnight Mountain, 10,165 ft — the range's high point) to the pinyon-juniper foothills at the forest boundary. Almost the entire high country is a post-Black Fire burn mosaic — regenerating parks and snag patches interlaced with surviving timber — and it hunts as big, vertical glassing country with brutal pack-outs.
Cover: Pinyon-juniper and oak woodland along the lower forest boundary rising through ponderosa pine to mixed conifer and aspen pockets on the crest; the 2022 Black Fire overlaid most of it with a mosaic of regenerating grass, forb, and locust-choked burn amid green islands of surviving timber.
Landmarks: Black Range crest / Continental Divide (west boundary) · Aldo Leopold Wilderness (eastern half lies in the unit) · McKnight Mountain (10,165 ft) and Reeds Peak · Hillsboro Peak and Emory Pass on NM 152 · Kingston (historic townsite at the unit's southern road corridor) · NM 59 corridor across the north end (Winston toward Beaverhead) · Animas, Las Palomas, and Percha creek drainages · Black Range Crest Trail #79 / Continental Divide Trail
Access
By definition the unit is Gila National Forest, so nearly everything inside the boundary is public — but access is concentrated on the perimeter. NM 152 over Emory Pass (through Hillsboro and Kingston) crosses the southern end and carries the main trailheads; NM 59 crosses the north end west of Winston; forest roads off NM 52 near Chloride and off the east side reach the forest edge. The interior — the Aldo Leopold Wilderness — is foot and horseback only, and the 2022 Black Fire left deadfall, washed-out tread, and hazard snags on many trails, with recovery work still ongoing; check current conditions with the Black Range Ranger District before committing to a wilderness route. The east foothill approaches are pinched in places by private ranch land below the forest line — most notably the Ladder Ranch along the Animas/Las Palomas country — so pick your entry from legal forest-boundary roads. Note the license split: 21A tags are valid only inside the forest boundary, which does not follow obvious terrain in the foothills.
Managers: USFS Gila National Forest (Black Range Ranger District), Small private inholdings (Kingston area and scattered ranch parcels)
Access points: Emory Pass on NM 152 — Black Range Crest Trail #79 trailheads (north toward Hillsboro Peak, south toward Sawyers Peak) · Railroad Canyon trailhead on NM 152 (Trails #128/#130) · NM 59 across the northern end of the unit (from Winston/NM 52 toward Beaverhead) · Forest roads west of Chloride and Winston off NM 52 (including the FR 226 Lookout Mountain area CDT access) · East-side forest-boundary roads above Hillsboro and Kingston
Species notes
Rocky Mountain Elk
common qualityThe headline hunt: the Black Range herd lives at lower density than the central Gila units — which is exactly why 21A draws easier — but the roadless Aldo Leopold country grows mature, record-book-capable bulls, and the post-Black Fire feed flush is working in the herd's favor. Success favors hunters who treat it as a pack-in wilderness hunt rather than a road hunt.
- →Commit to the backcountry — backpack or horse hunts into the Aldo Leopold canyons consistently outperform perimeter road efforts in this unit.
- →Build the hunt around the Black Fire mosaic: glass regenerating burn parks at canyon heads and along the crest at first and last light, where feed now concentrates elk.
- →In September, work the steep east-slope drainage heads calling between benches; wallows and the few live waters in Animas, Palomas, and Percha country are controlling in dry years.
- →Cover country with optics before boots — elk density is modest, so find the drainage holding animals rather than grinding blind through burn deadfall.
- →Plan the pack-out before the shot: the east-slope canyons drop thousands of feet and there is no motorized retrieval inside the wilderness.
Mule Deer
common opportunityMule deer are scattered through the foothill woodland and burn-opened mid-slopes at modest density — an honest opportunity hunt on the same country as the elk, with the occasional better buck wintering off the crest.
- →Hunt the pinyon-juniper/ponderosa transition band and oak-brush canyon heads along the east forest boundary rather than the deep crest timber.
- →Glass burn edges and regenerating parks in the first and last hour; the fire opened sight lines that didn't exist before 2022.
- →Late in the fall, work the lower south-facing foothill slopes as deer drift down ahead of crest snow.
- →Still-hunt saddles and ridge spines between drainages mid-morning after glassing sessions.
Black Bear
common opportunityBlack bears are well established the length of the Black Range, part of the greater Gila-region population, with the burn's berry, acorn, and forb flushes now pulling bears into the open in fall.
- →Glass oak-brush canyons and mast slopes off the crest at dawn and dusk in early fall.
- →Check regenerating burn for feeding sign — torn-up ground and scat concentrations mark active feed patches.
- →Work the live-water creeks (Animas, Percha country) in dry years where sign concentrates.
- →Carry the tag while elk hunting — most 21A bears are taken as add-on opportunities.
Cougar
common opportunityClassic lion country — a rugged, empty range stacked over deer and elk winter ground. Cougars are consistently present but rarely killed without hounds, snow, or luck.
- →Cut tracks after crest snowfalls along NM 152, NM 59, and perimeter forest roads.
- →Still-hunt rimrock and canyon pour-offs above foothill deer concentrations.
- →Stay alert at gray light around burn-edge deer feed while hunting other species.
- →Verify current NMDGF cougar zone harvest status before and during the hunt.
Pro tips
- →Treat this as a wilderness pack hunt, not a road hunt — the hunters who consistently kill in 21A are the ones a canyon or two beyond the trailheads.
- →Call the Black Range Ranger District before the hunt for current trail conditions; Black Fire deadfall and washouts still dictate which wilderness routes are realistic.
- →The burn is the new playbook: pre-scout regenerating parks on satellite imagery and build glassing plans around them.
- →Draw odds here beat the central Gila units for genuinely wild country — a smart every-year application for DIY hunters who can handle the terrain (New Mexico has no bonus points).
- →Know exactly where the forest boundary runs — your 21A license stops at it, and the foothill line is invisible on the ground.
- →Water is the scarcest resource on this dry side of the range — stage extra in the truck and know your backcountry sources before you commit.
Watch out for
- !The Aldo Leopold Wilderness is strictly non-motorized — no vehicles, no bikes, no game carts past the boundary.
- !Post-Black Fire hazards are real: standing snags that drop in wind, deadfall-buried trails, ash pits, and flash-flood-prone drainages during storms.
- !Pack-outs from the east-slope canyons are brutal — thousands of feet of climb; plan meat retrieval before you shoot.
- !Private ranch land (including the Ladder Ranch) blocks some east-foothill approaches below the forest line; trespass is enforced.
- !NM 152 over Emory Pass can ice or close in winter storms, and fire restrictions or area closures are common on the Gila in dry years.
- !Cell service is absent in the backcountry — a satellite communicator is standard equipment here.
Logistics
Truth or Consequences on I-25 is the working base — fuel, motels, groceries — about 30–45 minutes from the east-side jump-offs. Hillsboro and Kingston on NM 152 and Winston/Chloride on NM 52 are tiny historic communities with little more than a cafe and no fuel to count on; top off in T-or-C. Camping is easy on forest ground along NM 152 and NM 59, but serious hunts mean backpacking or horse-packing into the wilderness with your own water plan. Cell coverage dies quickly off I-25 and is effectively absent in the backcountry — carry a satellite communicator. NM 152 over Emory Pass is slow and winding; give access drives more time than the map suggests.
