In short

A high-elevation, half-open draw-only unit with more hunters than in 2022. Most of Unit 58 sits between 9,000 and 10,000 feet, with more grass and meadow than anything else and conifer next, then shrubland. About half of the unit is huntable public land, and just under a fifth of that ground is more than an hour and a half on foot from a drivable road. CPW's survey counted 906 hunters across all seasons in 2024, up from 775 in 2022, while second rifle success rose from 19% to 24%. Every license here is drawn.

Licenses and draw

Access

Unit 58 has 5 trailheads and about 548 miles of road any vehicle may drive on the second rifle opener, plus 108 more that need high clearance. About half of the huntable public ground is within a 30-minute walk of a drivable road, and just under a fifth 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 58.

  • 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 Buffalo Peaks herd (E-22) estimate for 2025 and hunter density, 2024.

Second rifle success rose from 19% to 24% between 2022 and 2024, while the season's hunters rose by just under half. Across all seasons, hunters rose by just under a fifth between 2022 and 2024. Unit 58 is one of 3 units in CPW's Buffalo Peaks herd unit (E-22), estimated at about 3,500 elk after the 2025 hunt, with 33 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.
