In short

A mid-elevation, mostly timbered draw-only unit. Most of Unit 361 sits between 7,000 and 9,000 feet, with more conifer than anything else and aspen next, then shrubland; only about 1% of it rises above 11,000 feet. About three-quarters of the unit is huntable public land, and almost none of that ground is more than an hour and a half on foot from a drivable road. CPW's survey counted 196 hunters across all seasons in 2024, down from 226 in 2022, while second rifle success fell from 42% to 26%. Every license here is drawn, as for all Colorado mule deer.

Licenses and draw

Access

Unit 361 has 3 trailheads and about 25 miles of road any vehicle may drive on the second rifle opener, plus 37 more that need high clearance. About two-thirds of the huntable public ground is within a 30-minute walk of a drivable road, and almost none 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 mule deer have behaved where they were studied, not where they are in Unit 361.

  • In a south-central Wyoming herd, mature bucks moved away from motorized routes into roadless cover during a rifle season while does stayed on their usual forage, and hunting barely changed when deer migrated.

    Rodgers et al., 2021 Single study

  • In Colorado's Gunnison Basin, GPS-collared mule deer made their fall migration from late October into early November, along corridors averaging about 17 miles.

The numbers

CPW harvest estimates 2022–2024 for the chosen season and all seasons, the State Bridge herd (D-8) estimate for 2025 and hunter density, 2024.

Second rifle success fell from 42% to 26% between 2022 and 2024, while the season's hunters fell by about a third. Across all seasons, hunters fell by just over a tenth between 2022 and 2024. Unit 361 is one of 5 units in CPW's State Bridge mule deer herd (DAU D-8), estimated at about 13,000 mule deer after the 2025 hunt, with 24 bucks per 100 does.

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.
