Overview
Unit 51B is a small unit of roughly 197 square miles west of US 84 in Rio Arriba County, wrapping the eastern side of the Chama River Wilderness where the Rio Chama cuts its red-rock canyon below Echo Amphitheatre. It supports healthy elk on public land, though mule deer numbers are limited here. Ownership is mixed — about two-thirds public Carson National Forest and BLM — with private ranches, notably in the northeast, that restrict access and participate in New Mexico's E-PLUS landowner-tag system. Confirm public status carefully before hunting.
Terrain
Red-rock canyon and mesa country along the Rio Chama rising into timbered mountains, with more forest cover in the southern portion.
Cover: Pinyon-juniper, sage and grassland on the mesas grading into ponderosa pine and mixed conifer in the southern high country, with oak brush and riparian cottonwood along the Chama.
Landmarks: Chama River Wilderness · Rio Chama canyon · Echo Amphitheatre · Carson National Forest · US 84 corridor
Access
About two-thirds public, with much of the accessible ground inside or bordering the Chama River Wilderness (foot/horseback only). Private ranches in the northeast restrict access and carry E-PLUS landowner elk tags — research private boundaries before hunting. Jicarilla Apache tribal land lies to the northwest and is closed to general NMDGF hunting. Access is primarily off US 84 and forest roads on the wilderness margins.
Managers: USFS Carson NF, BLM, private ranch (E-PLUS), NM State Trust
Access points: US 84 corridor between Abiquiu and Tierra Amarilla · Forest Road 151 / Rio Chama access into the wilderness margin · Echo Amphitheatre area · Southern forest roads off US 84
Species notes
Rocky Mountain Elk
common qualityThe primary draw — a healthy public-land elk herd centered on the Chama River Wilderness and the southern timber.
- →Hunt the timbered southern portion and wilderness-edge drainages
- →Glass canyon rims and grassy benches at first and last light
- →Work water and wallows in the dry early-season rut
- →Slip into the foot-access wilderness to leave road pressure behind
Mule Deer
limited opportunityMule deer numbers are limited in this unit, but a few good bucks come off the pinyon-juniper mesas and canyon breaks each year.
- →Glass pinyon-juniper and sage transitions at dawn
- →Work canyon rims and mesa benches above the Chama
- →Still-hunt oak-brush pockets in the higher southern country
Pro tips
- →Research private-land and E-PLUS boundaries in the northeast before you hunt — access is genuinely mixed here
- →The southern timber and Chama River Wilderness hold the best public elk ground
- →Be ready to hunt on foot — much of the quality country is wilderness or road-limited
- →Water controls the September rut — scout seeps, tanks and wallows first
- →Don't count on mule deer as a primary target; treat bucks as a bonus
Watch out for
- !Private ranches in the northeast restrict access and carry E-PLUS landowner tags
- !Chama River Wilderness is foot/horseback only — no vehicles
- !Jicarilla Apache reservation land to the northwest is closed to general NMDGF hunting
- !Limited road access — plan for foot travel into the best country
- !Water is scarce on the mesas in dry years
Logistics
Tierra Amarilla and Chama offer fuel and limited supplies; Española to the south is the larger hub for lodging, groceries and gear. Access hinges on US 84 and a limited road network on the wilderness margins, so plan for foot travel into the best country and self-sufficient camping. Cell coverage is unreliable off US 84.
Nearest towns: Tierra Amarilla, Abiquiu, Chama, Los Ojos, Española
