Where to Find Elk in Unit 21B
We target three habitat bands in the Magdalenas.
North Baldy/South Baldy (9,500–10,700 ft)
High spruce-fir and aspen on the Baldy peaks hold mature bulls pre-rut and through archery.
Mixed Conifer Benches (8,000–9,500 ft)
North-facing benches with conifer and aspen are primary bedding. Rifle season bulls hold here and feed into openings at dawn/dusk.
Ponderosa/Oak Foothills (7,000–8,000 ft)
Lower ponderosa parks concentrate elk during cold storms. Water tanks on the east and south foothills are reliable.
Unit 21B terrain and land status
Measured from the unit boundary, not from the agency write-up
The lay of it
- 3,970–6,556 ft on a terrain sample , averaging 5,306 ft ; peaks can run higher.
- 2,568.6 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
- 191 tanks
- 6 springs
- 4,195 stream segments
- 21 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.

Data from 2021 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.
