Colorado Unit 142 Pronghorn Antelope Hunting Guide

Colorado Unit 142 sits entirely on public ground — 100% of its 235,672 acres are open to public access, a figure that immediately sets it apart from many eastern plains units in this state where private land dominates the landscape. For hunters researching pronghorn hunting opportunities in Colorado, that single statistic is worth pausing on: a unit this size with full public access is uncommon, and it shapes nearly every strategic decision a hunter will make here, from scouting to stand placement to how much competition to expect in the field.

This is a limited-quota unit from top to bottom. There is no general season option in Unit 142 — every pronghorn hunt here, including hunts for antlered and either-sex animals, runs through Colorado's draw system. That means hunters can't simply buy a tag over the counter and show up; access to this unit is controlled entirely by the draw, which has direct implications for how hunters should plan their application strategy and what they can expect once they're holding a tag.

Elevation in the unit ranges from 4,374 to 5,907 feet, consistent with the kind of open, rolling terrain pronghorn prefer — sagebrush flats and shortgrass plains country typical of Colorado's eastern and southeastern pronghorn range. With zero wilderness acreage recorded for the unit, there are no wilderness-access restrictions to worry about here; this is drive-and-glass, walk-and-stalk country, not pack-in terrain.

HuntPilot Analysis: Is Unit 142 Worth Applying For?

The harvest numbers out of Unit 142 make a strong case for this unit being a serious consideration for pronghorn hunters, particularly those who prioritize actually filling a tag. Success rates across the last five recorded seasons have been consistently solid: 45% in 2025 (535 of 1,183 hunters), 60% in 2024 (90 of 151 hunters), 49% in 2023 (105 of 213 hunters), 41% in 2022 (68 of 166 hunters), and 57% in 2021 (112 of 198 hunters). That's a five-year range of 41% to 60%, with most years landing in the high-40s to high-50s range — numbers that reflect a healthy, huntable population and reasonably favorable terrain for pronghorn hunting tactics.

What's notable is the jump in hunter numbers in 2025 — 1,183 hunters compared to totals ranging from 151 to 213 in the four prior years. Even with that much larger pool of hunters afield, success held at 45%, which suggests the unit can absorb increased pressure without success rates collapsing. That's a meaningful data point for hunters trying to gauge whether a more crowded season will hurt their odds of connecting.

The counties overlapping Unit 142 carry a strong history of producing trophy-class pronghorn, based on records tracked in HuntPilot's trophy database. That trophy pedigree, paired with consistent harvest success, makes this a unit worth strong consideration for hunters who've built points and are looking for a place to cash them in. It's important to frame that trophy note correctly, though — these records are logged at the county level, not the unit level, meaning the same entries are shared across neighboring units that overlap the same counties. The trophy animals attributed to this general area may have come from anywhere within those county boundaries, not necessarily from inside Unit 142's specific footprint. Still, a strong regional trophy history combined with solid harvest success is a combination that doesn't show up everywhere, and it's a legitimate reason to put this unit on a short list.

One data point worth tempering expectations around is the buck:doe ratio. Across six survey years from 2018 to 2024, the average buck:doe ratio in Unit 142 sits at 38:100. That's a modest ratio by pronghorn standards and suggests a doe-heavy herd structure rather than one stacked with mature bucks. It doesn't mean trophy bucks aren't present — the county-level trophy history says they are — but hunters shouldn't expect to see bucks behind every doe group. Glassing will matter, and covering ground to find the right buck will likely be part of a successful hunt here.

Given 100% public land, consistent harvest success, and a real trophy history in the surrounding counties, Unit 142 earns a favorable recommendation for hunters who draw a tag — particularly those willing to put in the legwork to find a mature buck rather than settling for the first animal spotted.

Harvest Success Rates

Unit 142's harvest data spans five recent seasons and paints a picture of a consistently productive pronghorn unit:

• 2025: 1,183 hunters, 535 harvested — 45% success
• 2024: 151 hunters, 90 harvested — 60% success
• 2023: 213 hunters, 105 harvested — 49% success
• 2022: 166 hunters, 68 harvested — 41% success
• 2021: 198 hunters, 112 harvested — 57% success

The five-year average lands comfortably in the mid-to-high 40s percent range, with two of the five years clearing 55%. For a species where open terrain often makes pronghorn visible but not always approachable, that's a strong track record. The 2024 season stands out with a 60% success rate on a smaller pool of 151 hunters, suggesting that in lower-pressure years, a well-prepared hunter has a better-than-even chance of filling a tag. The spike in hunter numbers for 2025 — nearly six times the hunter count of 2024 — and the fact that success still held at 45% is a strong signal that this unit's pronghorn population and public-land access can support a much larger hunting pressure load without success rates falling off a cliff.

Trophy Quality

Trophy records tied to the counties overlapping Unit 142 show a strong history of trophy-class pronghorn production. This is a meaningful data point for hunters weighing where to spend points, but it comes with a necessary caveat: because trophy entries are logged by county rather than by specific hunt unit, the same record-book animals credited to this area are shared with neighboring units that fall within the same counties. A trophy pronghorn attributed to the region may have been taken anywhere within those county lines, not necessarily inside Unit 142's exact boundary.

That said, a strong regional trophy history paired with the unit's full public-land access and solid harvest success rates is a combination that suggests real trophy potential exists here for hunters willing to be selective. The modest buck:doe ratio (38:100 average across recent surveys) indicates that mature bucks aren't necessarily common relative to the doe population, which reinforces the idea that trophy hunters should expect to do real scouting and glassing work rather than expecting mature bucks to be abundant on the landscape.

Herd Health & Population Trends

Survey data covering six years from 2018 through 2024 shows an average buck:doe ratio of 38:100 in Unit 142. This is on the lower end for pronghorn herds and suggests a doe-dominant population structure. Hunters should read this not as a red flag on herd health — harvest success has remained strong and consistent across the same period — but as a sign that bucks are a smaller proportion of the visible population at any given time. This reinforces the value of covering ground and glassing multiple groups rather than committing to the first band of pronghorn encountered, since does will significantly outnumber bucks in most groups.

The combination of steady harvest success and a long-running survey dataset (six years is a solid sample size for trend purposes) gives hunters reasonable confidence that the herd in this unit is stable and capable of sustaining the draw-only hunting pressure the unit currently receives.

Access & Terrain

Unit 142 is entirely public land — all 235,672 acres are open to public access, with zero private-land inholdings reducing that figure. This is as DIY-friendly as a unit gets from a land-access standpoint; hunters don't need to negotiate private land permission or budget for a guided hunt just to get onto huntable ground, which stands in contrast to many Colorado pronghorn units where private land dominates and public access is scarce or scattered in small parcels.

Elevation across the unit runs from 4,374 to 5,907 feet, consistent with open sagebrush and shortgrass plains terrain typical of pronghorn country in this part of Colorado. There is no wilderness acreage in Unit 142, meaning there are no wilderness-specific access restrictions and no requirement for specialized backcountry travel — this is terrain that rewards a truck, good optics, and the willingness to walk when a stalk is called for.

Because the entire unit is public, hunters can expect other hunters to be working the same ground, especially in high-pressure years like 2025. Pronghorn country offers limited opportunities to escape other hunters on foot — the open terrain that makes pronghorn visible from a distance also means hunters can often see each other from a distance, and stalks can be disrupted by other parties working the same group of animals. Scouting ahead of the season to identify less-trafficked pockets of the unit, water sources, and travel corridors is worth the time investment. HuntPilot's mapping tools, including public land overlays, can help hunters identify specific access points and terrain features within the unit's boundary before setting boots on the ground.

How to Apply

Every pronghorn hunt in Colorado Unit 142 is allocated through the state's limited-quota draw system — there is no general season or over-the-counter option here. Hunters, whether resident or nonresident, must apply through Colorado Parks and Wildlife's draw application process to be eligible to hunt this unit.

Colorado's draw operates on a true preference point system for pronghorn: hunters who accumulate enough preference points over multiple years of unsuccessful application eventually reach a point level high enough to guarantee a tag in many hunts, since the highest point holders draw first. This is different from a pure weighted lottery — point accumulation has real, predictable value over time in Colorado's system. Residents and nonresidents apply through separate pools, so draw dynamics differ by residency.

Because Unit 142 is limited-quota only, hunters without points should not expect to draw on a first attempt in most cases, though specific draw statistics for this unit should be checked directly rather than assumed. Application dates, fees, and current draw odds change every cycle — for the most current information, hunters should check HuntPilot's Colorado state page at /states/CO or Colorado Parks and Wildlife's official application portal before applying.

Frequently Asked Questions

What is the terrain like in Colorado Unit 142? Unit 142 sits at elevations between 4,374 and 5,907 feet, consistent with open plains and sagebrush terrain typical of pronghorn habitat in this region of Colorado. The unit carries no wilderness designation, meaning it's accessible, non-technical terrain suited to vehicle-based scouting and glassing rather than backcountry travel.

What is harvest success like in Unit 142? Success rates have ranged from 41% to 60% over the five most recently recorded seasons (2021-2025), with most years landing in the mid-to-high 40s to high 50s percent range. Even when hunter numbers spiked to over 1,100 in 2025, success held at 45%, indicating the unit handles increased pressure reasonably well.

How big are the pronghorn in Unit 142? The counties overlapping Unit 142 carry a strong history of producing trophy-class pronghorn, according to trophy records in HuntPilot's database. However, this is a county-level statistic shared with neighboring units, not unit-exact data. The buck:doe ratio in recent surveys (38:100 average) suggests bucks are a minority of the visible population, so trophy hunters should plan on selective glassing rather than expecting abundant mature bucks.

Is Unit 142 worth applying for? Based on available data, yes — particularly for hunters who value both a reasonable chance at filling a tag and a shot at a trophy-class buck. The combination of 100% public land, consistent harvest success in the 41-60% range, and a strong regional trophy history makes this a unit worth prioritizing once a hunter has sufficient points for a competitive application.

Is Unit 142 a good option for public-land DIY pronghorn hunters? Yes. With 100% of the unit's 235,672 acres classified as public land, Unit 142 removes the private-land access barrier that limits many other Colorado pronghorn units. Hunters should still expect company in the field, particularly in higher-pressure years, since open pronghorn terrain offers little natural cover from other hunting parties.
