Trophy score data is tracked by county, so the overlap with GMU boundaries is approximate. These numbers tell you whether the area is capable of growing big animals — they do not indicate public vs. private land. Big elk can come from anywhere; most elk in the lower 48 trace back to Yellowstone stock that was transplanted west after the species was nearly extirpated in the early 1900s.

Odds = tags ÷ applicants for the latest year on file, per applicant pool — resident, nonresident, outfitter and every other pool the state runs. Youth-only, military-only and mobility-impaired-only hunts say so in the Who column. Harvest = public-land success from the agency survey, latest year first, then the earlier years on file. Tap a hunt for its own page.
Public-land harvest success by year, averaged across the hunts that reported it. Watch the direction: units come into favor and go out of it.
