In short

A mid-elevation, half-open OTC unit. Most of Unit 80 sits between 7,000 and 9,000 feet, with more conifer than anything else and shrubland next, then farmland. Just under three-fifths of the unit is huntable public land, and under a tenth of that ground is more than an hour and a half on foot from a drivable road. CPW's survey counted 3,213 hunters across all seasons in 2024, up from 2,984 in 2022, while second rifle success rose from 14% to 17%. Second and third rifle sell over-the-counter bull licenses; the other seasons are draw only.

Licenses and draw

Second rifle in Unit 80, 2026: an over-the-counter bull license (E-M-000-U2-R) and a draw cow license (E-F-080-O2-R).

Access

Unit 80 has 27 trailheads and about 663 miles of road any vehicle may drive on the second rifle opener, plus 180 more that need high clearance. About three-fifths of the huntable public ground is within a 30-minute walk of a drivable road, and under a tenth is more than an hour and a half away.

Hunt codes from the CPW 2026 big game brochure. A code valid in several units counts every hunter in all of them.

Draw results are CPW's primary-draw recap and drawn-out-at reports, 2024–2026, adult licenses. "Drawn out at" is the lowest preference-point level that drew a license; "Leftover" means licenses remained after the draw. A code valid in several units counts every applicant for all of them.

What the research says for this season

Findings from published studies and agency work, as tendencies. They describe how elk have behaved where they were studied, not where they are in Unit 80.

  • In Montana GPS work, rifle-season elk tended to hold about a mile or more from open motorized routes, in blocks of 5,000 acres or more.

    Ranglack et al., 2017 Established finding

  • At Oregon's Starkey Experimental Forest, bulls chose more canopy and kept away from open roads by day during hunts, and the shift was stronger in rifle seasons than in archery.

    Smith et al., 2022 Single study

  • In Montana, collared elk shifted onto ground closed to public hunting once rifle seasons opened, ahead of security cover on public land.

    Proffitt et al., 2013 Established finding

The numbers

CPW harvest estimates 2022–2024 for the chosen season and all seasons, the Lower Rio Grande herd (E-32) estimate for 2025 and hunter density, 2024.

Second rifle success rose from 14% to 17% between 2022 and 2024, while the season's hunters held about steady. Across all seasons, hunters held about steady between 2022 and 2024. Unit 80 is one of 2 units in CPW's Lower Rio Grande herd unit (E-32), estimated at about 15,000 elk after the 2025 hunt, with 20 bulls per 100 cows.

What this page can't tell you

Closures, private ground, this year's pressure and animal locations.
  • Closures. Forest, fire and road closure orders change through the season and aren't checked here. The managing agency's current order governs.
  • Private ground. Land with no public hunting access is hunted only with the owner's permission, and the public-land share above leaves it out.
  • This year's pressure. CPW's hunter numbers run a year or more behind the season you're planning.
  • Animal locations. These are terrain, access, harvest and herd figures, and CPW's mapped ranges are range lines; none of them places an animal. Finding elk is still your job.
