Unit 18A (Truxton Flats and Aubrey Valley)
Arizona Hunting Guide — Pronghorn, Mule Deer
GMU 18A is the big open country west and north of Prescott, running out past Seligman and Hackberry — Truxton Flats, the Seventyfour Plains, Aubrey Valley and Red Lake Flat, with the Cottonwood Cliffs, Cross Mountain and the Juniper Mountains breaking up the grass. Pronghorn and mule deer share it, and the two hunts could not be less alike: pronghorn live on the flats and deer live everywhere except the flats, in dense pinyon and juniper. AZGFD draws both as limited tags. The thing to understand before you apply is access — remote residential subdivisions have spread across much of 18A, several ranches are closed outright, and knowing exactly where you are standing is part of hunting it.

Pronghorn Hunting in Unit 18A
GMU 18A is the big open country west and north of Prescott, running out past Seligman and Hackberry — Truxton Flats, the Seventyfour Plains, Aubrey Valley and Red Lake Flat, with the Cottonwood Cliffs, Cross Mountain and the Juniper Mountains breaking up the grass. Pronghorn and mule deer share it, and the two hunts could not be less alike: pronghorn live on the flats and deer live everywhere except the flats, in dense pinyon and juniper. AZGFD draws both as limited tags. The thing to understand before you apply is access — remote residential subdivisions have spread across much of 18A, several ranches are closed outright, and knowing exactly where you are standing is part of hunting it.
Where the pronghorn are in 18A: Truxton Flats, the Seventyfour Plains and Aubrey Valley
18A's pronghorn herd rises and falls with the rain, and AZGFD says so plainly — population follows precipitation and range condition. What's changed is not the grass but the deeds. Remote real-estate subdivision is taking a significant bite out of the huntable area, and the agency names the places it's hitting hardest.
The flats the agency names, and what's happening to them
Mormon Peaks, Chino Wash, Markham Well Flat, Echeverrias Flat, Aubrey Valley and the Antelope Valley subdivision area are all being affected by development. Most of that country is still huntable. The guide's wording is worth taking literally though: extreme caution and knowledge of your location are mandatory. Know your position to the parcel, not to the quarter-section.
Where to start instead
Truxton Flats, the Seventyfour Plains and Hackberry are the other three the agency lists, and the Truxton Flat country in the northwest corner is mostly BLM — public, accessible, and the most straightforward place in 18A to put a plan together. On our terrain layer the Seventyfour Plains sit at 5,338 feet and Red Lake Flat at 5,678, with Aubrey Valley at 5,239 and the Yampai Divide at 5,588. That's the elevation band this unit's pronghorn live in.
The high ground that makes it glassable
Pronghorn country is flat, but 18A gives you edges to work from. The Cottonwood Mountains reach 6,625 feet, Cross Mountain 6,419, Slate Mountain 5,933, Tin Mountain 5,884, Sugarloaf Peak 5,798, Twin Buttes 5,787 and Cherokee Point 5,722. The Cottonwood Cliffs at 4,746 give you a rim over the southwestern flats. Get on one of those before light and let the glass cover the ground your boots can't.
Water, and the private-land question
The unit holds roughly 275 stock tanks and 57 springs, with Truxton Spring and Crozier Canyon Spring inside the boundary. There's private land throughout. AZGFD's ask is simple and worth honouring: do your best to get permission, because that's what preserves the opportunity for the next hunter. Where ranch access boxes exist, sign in and put the green permit tag in your windscreen.
Unit 18A terrain and land status
Measured from the unit boundary, not from the agency write-up
The lay of it
- 3,951–5,955 ft on a terrain sample , averaging 5,176 ft ; peaks can run higher.
- 1,226.6 sq mi inside the boundary. Big enough that picking one drainage beats driving three.
Who owns the ground
- National Forest — 60%
- State Trust — 8%
- Private / Other — 32%
Roughly 68% is public. Carry a land-status layer anyway — these are area percentages, not a map of where the boundaries fall.
Water on the ground
- 275 tanks
- 57 springs
- 3,931 stream segments
- 5 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: Cottonwood Mountains (6,625 ft), Cross Mountain (6,419 ft), Slate Mountain (5,933 ft), Tin Mountain (5,884 ft)
Holding ground: Red Lake Flat (5,678 ft), Yampai Divide (5,588 ft), Seventyfour Plains (5,338 ft), Truxton Spring
Every one of these was tested against the unit polygon before it went on the map. They are starting points, not agency recommendations.
