Overview
Unit 39 spans roughly 2,644 square miles of the central New Mexico high plains, boxed by paved highways: NM 41 on the west from Willard up to Moriarty, I-40 across the north to east of Santa Rosa, and US 84 and US 60 forming the eastern and southern lines down to Fort Sumner. This is grassland and shortgrass prairie broken by mesas, arroyos and scattered pinyon-juniper, cut into thirds by US 285 and US 54. Pronghorn are the clear headline here — antelope success runs in the 80% range on quality plains bucks — with a secondary, lower-density mule deer opportunity in the brush and juniper breaks. The catch is land status: the unit is overwhelmingly private ranch and State Trust ground, so access, not game, is the limiting factor.
Terrain
Gently rolling high-plains grassland cut by shallow arroyos and low mesas, with pinyon-juniper appearing on steeper hills, draws and mesa rims.
Cover: Shortgrass and desert-grass prairie with yucca, cholla and snakeweed, grading into pinyon-juniper on hills and arroyo breaks; dryland and irrigated farm fields near the highway corridors.
Landmarks: Estancia Basin · Pintada Arroyo · US 285 / US 54 corridors · Encino · Vaughn · Cline's Corners
Access
This is predominantly private ranch and NM State Trust land — there is very little federal public ground. Antelope tags are largely allocated on private land under New Mexico's landowner (A-PLUS/private-land) system, and many of the best pronghorn ranches are hunted only with landowner authorization or through an outfitter. State Trust sections require a valid recreational access permit and are often landlocked behind private fences. Confirm land status and secure written permission before hunting; the paved unit-boundary highways and county roads provide the travel network but most of it fronts private ground.
Managers: private ranch, NM State Trust, BLM
Access points: I-40 exits at Moriarty, Clines Corners and Santa Rosa · US 285 north-south through Encino and Vaughn · US 54 through Vaughn and Duran · US 60 along the southern boundary · County-maintained ranch roads off the highway corridors
Species notes
Pronghorn
abundant qualityThe reason to draw this unit — open central-plains pronghorn with very high buck-success rates on the grassland ranches.
- →Glass from mesa rims and high points at first light to locate herds on the open grass
- →Use terrain folds, arroyos and windmills to close the last few hundred yards
- →Pattern bucks around stock tanks and windmills in the dry late-summer heat
- →Judge horn mass and prong length carefully — this country grows heavy bucks
Mule Deer
limited opportunityA lower-density, secondary opportunity — mule deer hold in the juniper breaks, arroyos and mesa country rather than the open plains.
- →Hunt pinyon-juniper transition and arroyo breaks at dawn and dusk
- →Glass mesa rims and brushy draws where deer bed out of the wind
- →Focus on cover near water and farm-field edges
Pro tips
- →Lock up access first — this unit is almost entirely private/State Trust, so a landowner tag or permission is the real tag
- →Water rules the hot late-summer hunt: inventory windmills and stock tanks and watch them at dawn
- →Glass big from mesa rims and high spots before committing to any stalk on the open grass
- →Use the constant plains wind and every arroyo and terrain fold to break your outline on the final approach
- →Bring a State Trust recreational access permit if you plan to hunt trust sections, and confirm they aren't landlocked
Watch out for
- !Access is the constraint, not game — most of the unit is private ranch and State Trust with little federal public land
- !Antelope tags are heavily tied to private-land/landowner allocation; open public opportunity is limited
- !State Trust sections need a valid access permit and are frequently landlocked behind private fences
- !Late-summer heat, lightning and relentless wind on the exposed plains
- !Water is scarce away from windmills and tanks — carry your own
Logistics
Santa Rosa (I-40) and Moriarty are the main hubs for fuel, lodging and groceries; Vaughn and Encino offer minimal services and gas. Expect long drives on ranch and county roads, hot late-summer antelope conditions, and self-sufficient logistics. Cell coverage is decent along I-40 and US 285 but drops off on the ranch interiors.
