Unit 28 (Gila Mountains, Eagle Creek and the Gila Box)
Arizona Hunting Guide — Bighorn Sheep, Mule Deer, Elk
Unit 28 is the Safford country of southeastern Arizona — the Gila Mountains, the Gila River corridor and the Whitlock Mountains, with Eagle Creek and Bonita Creek cutting down from the north and the Gila Box between them. It carries two kinds of bighorn: a Rocky Mountain population north of U.S. Highway 70 that is the larger of the two, and a smaller desert bighorn herd. Mule deer are spread unit-wide at low density on Game and Fish water catchments and produce exceptional bucks, and a limited-opportunity elk hunt exists along the San Carlos Reservation boundary. The unit runs over 2,200 square miles with a mix of National Forest, BLM, State Trust and large private mining holdings, so access planning matters as much as scouting.

Answer a few questions about your tag, your season and your rig, and the Field Intelligence Report builds a print-ready Arizona Unit 28 guide around your hunt: three ranked spots with morning, afternoon and evening plays, a day-by-day plan, topo maps with every pin numbered, a camp and access plan, the legal and retrieval rules for this unit, shot discipline, a meat-care and pack-out plan, and a pre-trip checklist. Every coordinate sits on land recorded as public.

Bighorn Sheep Hunting in Unit 28
Unit 28 is the Safford country of southeastern Arizona — the Gila Mountains, the Gila River corridor and the Whitlock Mountains, with Eagle Creek and Bonita Creek cutting down from the north and the Gila Box between them. It carries two kinds of bighorn: a Rocky Mountain population north of U.S. Highway 70 that is the larger of the two, and a smaller desert bighorn herd. Mule deer are spread unit-wide at low density on Game and Fish water catchments and produce exceptional bucks, and a limited-opportunity elk hunt exists along the San Carlos Reservation boundary. The unit runs over 2,200 square miles with a mix of National Forest, BLM, State Trust and large private mining holdings, so access planning matters as much as scouting.
Where the rams are in 28: Eagle Creek first, then Bonita Creek and the Gila Box
Unit 28 holds both Rocky Mountain and desert bighorn, and the Rocky Mountain population is the bigger of the two. They live north of U.S. Highway 70. The last survey was 2023 and AZGFD reports the population healthy.
The Eagle Creek drainage — where most of them are
The guide is unambiguous: the majority of the sheep are in Eagle Creek. Best access is the Lower Eagle Creek Pump Station Road. One complication to sort out before you go — Freeport McMoRan's Morenci copper mine holds a large block of private ground in this country, and it includes Eagle Creek. Eagle Creek itself is open to the public. For the rest of Freeport's holdings, the guide recommends contacting someone in security at the Morenci office to discuss access, and notes they won't allow entry to active mining sites.
Bonita Creek
Reached from the Safford area on either the Solomon Pass road or the Bonita Creek–Sanchez Road. The sheep sit in the broken country between Bonita Creek, Eagle Creek, the Gila Mountains and the Gila River — and as the guide puts it, the terrain is very rough, rugged and steep with access limited to a few roads.
The Gila Box
Very limited access. You either hike in from the Eagle Creek or Bonita Creek side, or you float the Gila River into it, depending on water levels. That's a genuine option here and worth considering if the river is up — it puts you into country almost nobody walks.
The canyons the agency tells you to scout
Gold Gulch, Bat Canyon, Turtle Mountain, Midnight Canyon, Horseshoe Canyon, Copperplate Canyon and Hot Springs Canyon. Those are the named spots on the map worth your preseason time, and the guide says a good deal of time spent scouting is what separates a decent ram from the best one available.
Getting around
US 191, US 70, I-10 and AZ 78 are the paved frame. Bitter Creek Road and the Gas Line Road give you graded gravel. The Black Hills Backcountry Byway, a BLM road, opens the country between US 191 and the Gila River. Safford, Thatcher, Duncan and Morenci are your services.
Unit 28 terrain and land status
Measured from the unit boundary, not from the agency write-up
The lay of it
- 2,780–5,736 ft on a terrain sample , averaging 3,955 ft ; peaks can run higher.
- 2,230.4 sq mi inside the boundary. Big enough that picking one drainage beats driving three.
Who owns the ground
- National Forest — 60%
- BLM — 15%
- State Trust — 8%
- Private / Other — 17%
Roughly 83% is public. Carry a land-status layer anyway — these are area percentages, not a map of where the boundaries fall.
Water on the ground
- 753 tanks
- 149 springs
- 438 stream segments
- 17 lakes
Counts from mapping data, so this is how many exist, not how many hold water in a dry year. Sitting water only pays where you find fresh tracks.
Named features inside the unit
Glass from: Maverick Hill (7,469 ft), Turtle Mountain (6,997 ft), Hells Hole Peak (6,909 ft), Guthrie Peak (6,569 ft)
Holding ground: Maverick Basin (6,476 ft), Hooker Gap (5,266 ft), Hells Hole (5,101 ft), Canteen Spring, Indian Spring
Every one of these was tested against the unit polygon before it went on the map. They are starting points, not agency recommendations.

Bighorn Sheep Success Rates
Bighorn Sheep Draw Odds
| Season | Tags | Applicants | Draw % | Pts (n/p) |
|---|---|---|---|---|
| Rifle — General Rifle bull/buck only (combined pool) | 3 | 447 | 0.2% | — |
| Rifle — Late Rifle Nov bull/buck only (combined pool) | 3 | 791 | 0.4% | — |
Data from 2023 draw results. Each row is one residency pool — read the label before the number. This agency publishes no point thresholds, so the Pts column stays blank and these are pool odds, not what a point total draws.
Open in Draw Odds EngineUnit 28 bighorn is a once-in-a-lifetime draw. Arizona runs bighorn through the same weighted bonus-point system as other big game — 20% of tags go to max-point holders first, and the remaining 80% run a random weighted draw. With only ~6 tags over three years and 1,228 applicants, odds per applicant run roughly 0.5%. Expect to need 15–25+ bonus points to be realistically competitive, and even then the draw is largely luck-driven. Arizona residents who harvest a bighorn are permanently excluded from applying again for that species.
