In short

A low-elevation, mostly open draw-only unit with more far-from-road ground than most units. Most of Unit 30 sits between 4,000 and 6,000 feet, mostly shrubland with pinyon-juniper after it. About three-quarters of the unit is huntable public land, and about a fifth of that ground is more than an hour and a half on foot from a drivable road. CPW's survey counted 218 hunters across all seasons in 2024, down from 255 in 2022, while second rifle success fell from 72% to 62%. Every license here is drawn, as for all Colorado mule deer.

Licenses and draw

Second rifle in Unit 30, 2026: a draw buck license (D-M-030-O2-R) and a draw doe license (D-F-030-O2-R).

  • D-M-030-O2-R buck, draw 2026 draw: residents drawn out at 2 points; nonresidents drawn out at 6 points

Access

Unit 30 has 30 trailheads and about 686 miles of road any vehicle may drive on the second rifle opener, plus 239 more that need high clearance. Just over half of the huntable public ground is within a 30-minute walk of a drivable road, and about 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 mule deer have behaved where they were studied, not where they are in Unit 30.

  • Across Utah and Nevada, GPS-collared mule deer avoided high-severity burns at fine scale for up to 30 years after a fire.

    Mills et al., 2026 Single study

  • 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.

    Kauffman et al., 2024 Single study

The numbers

CPW harvest estimates 2022–2024 for the chosen season and all seasons, the Bookcliffs herd (D-11) estimate for 2025 and hunter density, 2024.

Second rifle success fell from 72% to 62% between 2022 and 2024, while the season's hunters fell by just under a fifth. Across all seasons, hunters fell by just over a tenth between 2022 and 2024. Unit 30 is one of 2 units in CPW's Bookcliffs mule deer herd (DAU D-11), estimated at about 8,000 mule deer after the 2025 hunt, with 42 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.
