In short

A high-country, mostly timbered draw-only unit with more far-from-road ground than most units. Most of Unit 46 sits between 8,000 and 11,000 feet, mostly conifer with alpine grass after it; just under a third of it rises above 11,000 feet. About three-quarters of the unit is huntable public land, and just under a third of that ground is more than an hour and a half on foot from a drivable road. CPW's survey counted 241 hunters across all seasons in 2024, down from 261 in 2022. Every license here is drawn.

Licenses and draw

Second rifle in Unit 46, 2026: a draw bull license (E-M-046-O2-R) and a draw cow license (E-F-046-O2-R).

Access

Unit 46 has 11 trailheads and about 154 miles of road any vehicle may drive on the second rifle opener, plus 78 more that need high clearance. About a quarter of the huntable public ground is within a 30-minute walk of a drivable road, and just under a third 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 46.

  • 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.

The numbers

CPW harvest estimates 2022–2024 for the chosen season and all seasons, the Mt Evans herd (E-39) estimate for 2025 and hunter density, 2024.

CPW counted 46 second rifle hunters in 2024; on so few, the success rate swings widely from year to year. Across all seasons, hunters held about steady between 2022 and 2024. Unit 46 is one of 4 units in CPW's Mt Evans herd unit (E-39), estimated at about 2,200 elk after the 2025 hunt, with 28 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.
