Colorado Unit 120 Pronghorn Antelope Hunting Guide

Colorado Unit 120 is a limited-quota pronghorn unit that draws steady interest from hunters chasing a solid, no-frills prairie hunt. With no general season here, every hunter afield in Unit 120 is doing so on a draw tag, and the unit has produced consistent harvest numbers over the past several seasons. For hunters weighing whether to spend points or apply cold in this part of Colorado, the data tells a fairly clear story about what to expect.

This is open pronghorn country, and like most units in this part of the state, it's defined by a mix of private agricultural ground and scattered public parcels. That land tenure situation matters enormously for how a hunt here actually unfolds, and it's one of the first things any applicant needs to understand before committing points to Unit 120.

HuntPilot Analysis: Is Unit 120 Worth Applying For?

The harvest numbers out of Unit 120 are the strongest argument in its favor. Over the last four seasons of data, success rates have held in a tight, respectable band: 51% in 2025, 56% in 2024, 53% in 2023, and 56% in 2022. That's a unit where, if you draw a tag, you have better than a coin-flip chance of putting a pronghorn on the ground — and in three of the last four years, better than a 50/50 shot by a comfortable margin. Hunter numbers have also been substantial, ranging from 616 to 831 hunters per year, which tells us this unit issues a meaningful number of tags rather than a token handful.

The catch is access. Public land sits at just 15% in Unit 120, meaning the large majority of the 332,350 acres here is private property. That's a critical number for anyone planning a DIY approach. With wilderness at 0%, there's no backcountry pack-in option to fall back on — this is flat-to-rolling prairie and agricultural country, and the public parcels that do exist will see concentrated pressure, especially during the first days of any hunt period. Hunters without landowner access, leases, or walk-in arrangements should expect to work hard for a tag that many other hunters are also competing to fill on the same limited public ground.

Trophy potential in the counties overlapping Unit 120 is moderate based on available record-book history. This isn't a unit with a deep or standout trophy pedigree, but it isn't devoid of history either — hunters have taken quality bucks from this area over time, and a patient hunter willing to pass mediocre bucks early in the season has a reasonable shot at a mature animal. This is not, however, a unit to bank on for an exceptional or record-class buck. Treat it as a solid opportunity unit with occasional above-average animals mixed in.

The buck-to-doe ratio from six survey years (2018–2024) averages 36:100. That's a modest ratio by pronghorn standards and suggests a herd with average buck representation rather than an exceptional age structure. It's not a red-flag number, but it does reinforce that this unit should be approached as a solid, attainable hunt rather than a trophy lottery ticket.

Bottom line: Unit 120 is worth applying for if a hunter's priority is a good chance at filling a tag and doesn't require extensive public-land access to do it. Hunters need to go in with a plan for private land access — whether that's a landowner relationship, a lease, or careful pre-season scouting of the public parcels that do exist. For hunters focused purely on trophy potential above all else, this unit is a reasonable but not exceptional option.

Harvest Success Rates

Unit 120's harvest data is one of its strongest selling points. Across four recent seasons:

• 2025: 761 hunters, 387 harvested — 51% success
• 2024: 690 hunters, 386 harvested — 56% success
• 2023: 616 hunters, 326 harvested — 53% success
• 2022: 831 hunters, 462 harvested — 56% success

This consistency matters. Success rates haven't dipped below 51% in any of the last four years, and hunter participation has stayed in a healthy range without ballooning to the point of overcrowding the harvest numbers. A hunter drawing a tag in Unit 120 in any recent year has had a genuinely good statistical chance of connecting, which sets this unit apart from many limited-quota pronghorn units where success rates swing wildly year to year.

Trophy Quality

Trophy records from the counties overlapping Unit 120 point to moderate trophy potential. This is shared county-level data — meaning the same historical entries are associated with neighboring units in the region as well, not exclusively Unit 120 — but it gives a fair read on what this corner of the state has historically produced. There's a real trophy history here, just not one defined by frequent exceptional bucks. Most hunters should plan on encountering a range of buck quality and use judgment on when to fill a tag versus holding out.

Given the modest 36:100 buck:doe ratio recorded across the six survey years reviewed (2018–2024), hunters shouldn't expect an unusually mature or heavily skewed buck population. This is an average-to-moderate age structure, consistent with the moderate trophy history in the surrounding counties. Hunters looking for a genuine trophy-class animal should temper expectations accordingly and treat any exceptional buck taken here as a bonus rather than the norm.

Herd Health & Population Trends

The buck:doe ratio data for Unit 120 spans six survey years between 2018 and 2024, averaging 36:100. This is a stable, unremarkable ratio — it doesn't suggest a herd under stress, nor does it suggest an unusually productive buck age class. Combined with the harvest data showing consistent hunter success in the 51–56% range over four years, the picture is one of a herd that can support meaningful hunting pressure while maintaining reasonable buck numbers year over year.

Hunters should note that no single-year spikes or crashes appear in this average, which is a good sign — it suggests the ratio has held reasonably steady across the survey period rather than being skewed by an anomalous year. That stability is a positive indicator for a unit hunters can plan around with some confidence.

Access & Terrain

This is where hunters need to pay close attention before applying. Unit 120 sits at a relatively low elevation range of 4,278 to 5,381 feet, consistent with open prairie and agricultural pronghorn country rather than mountainous terrain. There's no wilderness designation in this unit (0%), so there's no backcountry component to the hunt — this is entirely accessible, drivable country.

The critical number is public land: just 15% of the unit's 332,350 acres is public. That means the vast majority of Unit 120 — roughly 85% — is private property. This is a unit where DIY hunters relying solely on public access will be working with a small footprint, and that public ground will likely see concentrated hunting pressure from other tag holders during the same period. Hunters without a private land arrangement, lease, or walk-in access agreement should scout public parcels carefully well before their hunt and have a backup plan, since competition for the limited public ground can be intense.

Given this land tenure reality, hunters should budget extra time for locating access before the season, rather than assuming public ground will be open and huntable on short notice. This unit is not well-suited to a last-minute, purely public-land DIY approach given the 15% public land figure — a hunter should have secured some form of access lined up in advance.

How to Apply

Colorado's pronghorn tags in Unit 120 are issued entirely through the state's limited-quota draw system — there is no general season here, so every hunter afield on an antlered or either-sex pronghorn tag has gone through the draw process to get there.

Colorado's draw operates on a true preference point system, meaning the highest point holders in a given applicant pool draw first. This is not a weighted lottery — a sufficiently high point total can effectively guarantee a tag in units where point requirements are known, though hunters should verify current point requirements for Unit 120 specifically before committing, as this changes with each application cycle.

Residents and nonresidents apply through separate pools, with nonresidents generally requiring more accumulated points to be competitive for the same unit and season structure compared to residents. Point levels required to draw in Unit 120 shift from year to year based on tag quotas and applicant demand, so hunters should not rely on outdated point-requirement figures from previous seasons or from unrelated units.

Application dates and fees change every cycle. For the current deadlines, fees, and draw odds, hunters should check HuntPilot's Colorado page at /states/co, which reflects the most current numbers directly from the state.

Frequently Asked Questions

What is the terrain like in Colorado Unit 120?

Unit 120 sits at a low elevation range of 4,278 to 5,381 feet, characteristic of open prairie and agricultural pronghorn habitat rather than mountainous terrain. There is no wilderness area within the unit (0%), so the entire hunt takes place in accessible, non-backcountry country. The defining terrain challenge isn't ruggedness — it's land tenure, with the majority of the unit under private ownership.

What is harvest success like in Unit 120?

Harvest success has been strong and consistent in recent years, running 51% in 2025, 56% in 2024, 53% in 2023, and 56% in 2022. Hunter participation during these years ranged from 616 to 831 hunters annually. This is one of the more reliable success-rate track records among limited-quota pronghorn units in the state.

How big are the pronghorn in Unit 120?

Trophy records from the counties overlapping Unit 120 indicate moderate trophy potential — there's a real history of quality bucks coming from this region, but it's not a unit known for producing exceptional or record-class animals with regularity. The average buck:doe ratio of 36:100 across six survey years (2018–2024) supports an average age structure rather than an unusually mature buck population. Hunters should expect solid, representative pronghorn rather than betting on a trophy-caliber buck.

Is Unit 120 worth applying for?

Yes, with a caveat. The harvest success data makes a strong case — hunters drawing a tag here have had better-than-even odds of filling it in every recent season on record. However, with only 15% of the unit's acreage classified as public land, hunters need a plan for accessing private ground, whether through a landowner relationship, lease, or diligent scouting of the limited public parcels. Hunters without that access plan should think carefully before committing points, since the public-land footprint alone may not support a comfortable DIY hunt.

What kind of tag do I need to hunt pronghorn in Unit 120?

Every pronghorn hunt in Unit 120 requires a limited-quota draw tag — there is no general season here. Hunters must apply through Colorado's preference point draw system, with separate resident and nonresident applicant pools, and successful applicants receive tags for antlered or either-sex pronghorn depending on the specific hunt drawn.
