Colorado GMU 84 Pronghorn Hunting
Custer, Fremont, Huerfano and Pueblo counties, southeast Colorado · 1,281 sq mi
Based on the EASIEST unit-wide buck or either-sex hunt code available to adult Colorado residents in the 2026 primary draw — the lowest preference-point tier that drew reliably. Private-land-only and Ranching for Wildlife hunts are excluded because neither is a unit-wide public-land opportunity — NOT because the public cannot draw them. A private-land-only license requires the hunter's own permission to hunt private ground; a Ranching for Wildlife license is valid on the participating ranches enrolled in that program. They are separate systems. Other weapons, seasons and nonresident applicants can require substantially more points. The band is a floor, not a target: even the easiest qualifying hunt here sits in that range.
What hunting GMU 84 is like
GMU 84 occupies the southern foothills and high plateaus of the Sangre de Cristo range, spanning from low desert scrub at 4,600 feet to alpine tundra above 12,300 feet. The unit covers 1,281 square miles and is rolling, with some steeper breaks; terrain data show that 66 percent of the unit is gentle, 25 percent moderate, and 9 percent steep or rugged. The country here includes both wide-open grasslands at lower elevations and broken timber-and-rock country higher up, but much of it is privately owned, which constrains where a public-land hunter can actually hunt.
About 24 percent of the unit (310 square miles) is publicly open to hunting — a mix of National Forest, BLM and State Wildlife Areas. An additional 3 percent is Colorado State Trust Land, but access there depends on CPW enrollment in the Public Access Program and is not guaranteed. The remaining 73 percent is private or unclassified ownership. This land-access structure means that despite the unit's size and elevation span, a hunter's actual options rest on the 24 percent of open ground.
Pronghorn range covers 60 percent of the unit overall. Winter Range is mapped on 21 percent, with 8 percent of the unit identified as Winter Concentration ground where pronghorn cluster during the cold months. The seasonal range mapping suggests pronghorn distribution shifts with season and weather, with more concentrated use on particular ground in winter. Hunting opportunity here peaks during autumn transitions, when pronghorn are active and moving.
The unit offers two limited seasons to public applicants: a Muzzleloader season from September 21 through September 29 for doe or buck, and a Rifle season from October 3 through October 11, also doe or buck. The Muzzleloader hunt falls during the Primary Rut and into the Late Rut phase, while the Rifle season occurs in the Late Rut phase. September temperatures average highs near 78 degrees with lows around 48, virtually no snowfall, and light winds. October brings cooler weather (highs near 67, lows near 37) and light snowfall averaging 1.8 inches. Draw difficulty for the easiest unit-wide hunts is Moderate (1–2 points), and overall hunter pressure is Moderate.

Land & access
About 24% of GMU 84 is public land a hunter can count on — National Forest, BLM and State Wildlife Areas. A further 3% is State Trust Land, which is huntable only where CPW has enrolled it.
- National Forest20%
- BLM3%

- Unclassified ownership2%
- Private71%
Colorado State Trust Land is open to public hunting only where it is enrolled in CPW's Public Access Program. Check current enrollment before planning around it.
“Ownership unclassified” means the source dataset does not record an owner for that acreage. It is not known to be public or private.
Where pronghorn live in the unit
Colorado Parks & Wildlife maps pronghorn seasonal ranges statewide. This is how much of GMU 84 each range covers — the single best clue to whether pronghorn are here in September, in November, or only passing through. The layers overlap, so they do not add to 100%.

GMU 84 pronghorn hunting FAQ
How much huntable public ground is there really?
About 24 percent of the unit (310 square miles) across National Forest, BLM and State Wildlife Areas is generally open to public hunting. The additional 3 percent in Colorado State Trust Land is huntable only on parcels enrolled in CPW's Public Access Program, making access there uncertain. Private land makes up 71 percent of the unit, so legal access is the main limit here, not terrain walkability.
Is this realistic for a hunter with no preference points?
An applicant with zero points can draw the Muzzleloader or Rifle season in the primary draw — the easiest unit-wide hunt codes draw reliably at 1–2 points, meaning people below that band sometimes draw anyway. The secondary draw (held in June, random, no points required or awarded) and the leftover list after the primary draw are additional routes. Over-the-counter archery licenses are also available if this unit's archery season is unlimited, though that detail is not specified in this data.
When is the rut, and which season overlaps it?
Pronghorn in Colorado enter the Primary Rut on September 6 and enter Late Rut / Post-Rut Recovery on September 26. The Muzzleloader season (September 21–29) spans both the Primary Rut and early Late Rut phases, when bucks are actively defending territory and pursuing does. The Rifle season (October 3–11) falls entirely in Late Rut / Post-Rut Recovery, when rut activity is declining.
What does the terrain actually look like, and can a hunter on foot cover much ground?
Two-thirds of the unit is gentle terrain and another quarter is moderate slopes; steep and rugged ground makes up only 9 percent. A hunter on foot will find much of this walkable, especially at the lower and middle elevations where pronghorn range is concentrated. However, the 24 percent that is open to public hunting is scattered across the unit, so legal access boundaries, not steepness, will be the main constraint on ground a hunter can actually work.
Do pronghorn stay in the unit year-round or do they migrate out in fall?
Winter Range is mapped on 21 percent of the unit and Winter Concentration on 8 percent, indicating pronghorn do remain on winter ground within the unit. However, the seasonal range mapping shows distribution shifts with season and weather; early fall hunting (September) is likely to find pronghorn more spread across the Overall Range, while later in the season they may concentrate more heavily. Weather and conditions influence timing of any shift.
What are the weather conditions during the hunt?
September offers pleasant weather: highs near 78 degrees, lows near 48, with virtually no snowfall and light winds. October cools considerably, with highs near 67 and lows near 37, along with light snowfall averaging 1.8 inches for the month. A hunter should prepare for a wide temperature range across the day and the possibility of wet snow mid-season, though it is generally not heavy.

Draw difficulty is a qualitative band, not published odds — the note under the summary above states exactly which hunt code it describes. Land shares are separate, non-overlapping categories: publicly owned is not the same as open to hunting, and State Trust Land is huntable only where CPW has enrolled it.
