New Mexico Hunting Guide — Mule Deer
GMU 51B covers the Sangre de Cristo foothills and mesa country south of Taos in north-central New Mexico. Pinon-juniper ridges, oak-brush benches, and ponderosa draws give mule deer a varied habitat base. Public-land access through Carson National Forest and BLM parcels produces solid mid-tier hunts.

Where to Find Mule Deer in GMU 51B
Unit 51B mule deer use a mix of ponderosa ridges, oak-brush benches, and pinon-juniper rims.
Ponderosa Ridges
Mid-to-upper ridges hold summer bucks into early archery before they drop with weather.
Oak-Brush Benches
Prime rifle-season habitat where bucks rut through oak and gambel thickets.
Unit 51B terrain and land status
Measured from the unit boundary, not from the agency write-up
The lay of it
- 6,444–8,002 ft on a terrain sample , averaging 7,475 ft ; peaks can run higher.
- 197 sq mi inside the boundary.
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
- 284 tanks
- 995 stream segments
- 2 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.
