Wyoming Unit 91 Pronghorn Antelope Hunting Guide
Wyoming Unit 91 is a high-country pronghorn antelope unit sitting at elevations ranging from 6,576 to 13,069 feet across 440,855 total acres. With 93% public land, this unit stands out as one of the most accessible big-game units in the state — hunters can cover ground without the constant frustration of private land boundaries that plague lower-elevation antelope country. The combination of exceptional public access, strong documented harvest success rates, and a well-established trophy history makes Unit 91 a unit worth serious attention from any pronghorn hunter doing their research.
What sets this unit apart from the broader Wyoming pronghorn landscape is the consistency of its harvest numbers paired with the quality of its genetics. The counties overlapping Unit 91 carry a strong history of trophy-class pronghorn production — and with multiple survey years confirming a healthy buck-to-doe ratio, the herd appears to be in solid shape. Whether hunters are chasing a true wall-hanger or simply want a high-probability tag in rugged, scenic terrain, Unit 91 delivers a compelling case.
The unit's wilderness component — 8% of total acreage — adds a layer of backcountry character without locking out nonresident DIY hunters. Wyoming law requires nonresidents to hire a licensed Wyoming outfitter when hunting in designated wilderness areas, but with 8% wilderness coverage, the vast majority of this unit's public land is fully accessible to do-it-yourself hunters of any residency. The high-alpine character of the terrain, rising to over 13,000 feet, shapes where pronghorn congregate seasonally and rewards hunters who put in the scouting work.
Harvest Success Rates
Unit 91's harvest data tells a story of consistently strong production. Across the most recent four years of available data, success rates have never dipped below 86% — a floor that many dedicated pronghorn hunters would envy.
In 2023, 66 hunters took the field in Unit 91 and 57 harvested pronghorn, producing an 86% success rate. The following year, 2024 saw 75 hunters with 70 harvests — a 93% success rate. Then in 2025, the unit posted its best performance in the dataset: 135 hunters afield, 127 harvested, and a 94% success rate.
The 2022 season offers additional context. That year, 429 hunters participated in the unit — a substantially larger field — and still achieved an 88% success rate with 377 animals harvested. The fact that success held above 85% with more than four times the hunter pressure seen in 2023 and 2024 indicates the unit carries real capacity, not just the inflated numbers that come with a small, lucky cohort.
These are not marginal success figures. A four-year average hovering near 90% places Unit 91 among Wyoming's more productive pronghorn units from a pure harvest efficiency standpoint. Hunters who draw a tag here go in with genuine, data-backed confidence that they will fill it.
Trophy Quality
The counties overlapping Wyoming Unit 91 carry a strong history of trophy-class pronghorn production. Based on available trophy records, this area has demonstrated consistent ability to produce animals that meet the benchmark for true trophy-class pronghorn. The trophy history here is not a one-decade spike — it reflects sustained genetic and habitat quality that has produced record-class animals across multiple periods.
For hunters targeting a legitimate wall-hanger rather than just filling a tag, Unit 91's high-country terrain and relatively lower hunting pressure in recent years (compared to the 2022 outlier) create conditions where mature bucks have room to develop. The combination of strong genetics, diverse elevation gradients, and 93% public land suggests that hunters willing to work for it will encounter trophy-caliber animals. This unit rates as a strong opportunity for hunters with genuine trophy ambitions, not merely a meat-hunting destination.
Herd Health & Population Trends
Wildlife survey data collected across four survey years from 2021 through 2024 shows an average buck-to-doe ratio of 55:100 in Unit 91. This figure reflects a healthy, well-structured herd. For pronghorn specifically, a buck-to-doe ratio in this range indicates that hunting pressure has not pushed the adult male population into imbalance — there are enough mature bucks in the population to provide quality hunting opportunity and to support normal breeding dynamics during the September rut.
Four years of consistent survey data adds reliability to this average. This is not a single-year snapshot that could reflect unusual survey conditions or a small sample. The trend across 2021–2024 paints a picture of a stable pronghorn population in a unit where management appears to be calibrated appropriately to the available habitat and hunter harvest levels.
Access & Terrain
Unit 91's 93% public land coverage is exceptional by any standard in Wyoming. Hunters are dealing with a unit where access friction is minimal — the vast majority of the landscape is open to DIY hunting without the need to knock on private landowner doors or pay trespass fees.
The elevation range tells its own story: 6,576 feet at the low end and 13,069 feet at the high end. This is not flat sagebrush basin antelope country. Unit 91 is high-country terrain with significant relief, and pronghorn here occupy a different ecological niche than the classic Wyoming shortgrass flats. The alpine and subalpine character of the upper elevations means hunters may be glassing from ridgelines and covering ground in rugged country. Physical conditioning and the ability to pack out an animal from broken terrain are practical considerations for anyone planning a DIY hunt here.
The 8% wilderness designation adds technical character to a portion of the unit. Nonresident hunters should be aware that Wyoming law requires a licensed Wyoming outfitter for hunting in designated wilderness areas — this applies to all nonresidents, regardless of species. At 8% of total acreage, wilderness makes up a relatively small fraction of Unit 91, meaning that the overwhelming majority of the unit's 440,855 acres is fully accessible to DIY nonresident hunters. Residents face no such restriction in any portion of the unit.
Hunters targeting the wilderness portion of the unit should factor outfitter costs into their planning. Those focused on the non-wilderness public land — which represents approximately 92% of the unit's accessible acres — can plan a self-guided hunt without that requirement.
HuntPilot Analysis
Is Wyoming Unit 91 worth applying for? The data says yes — with important caveats depending on what hunters are looking for.
For hunters prioritizing harvest success, Unit 91 is one of the more compelling options in the state. A four-year success average near 90%, validated across both high-hunter-pressure years (429 hunters in 2022) and lower-pressure years (66–135 hunters from 2023–2025), demonstrates that this unit reliably produces. The 93% public land figure eliminates most of the access headaches that frustrate hunters in units with fragmented ownership patterns.
For trophy hunters, the available data supports genuine optimism. The counties overlapping Unit 91 have a well-documented history of producing trophy-class pronghorn, and the 55:100 average buck-to-doe ratio from four years of surveys indicates the herd structure supports mature buck development.
The tag quota data provides additional signal worth noting. HuntPilot's data shows that Type 1 tags increased significantly from 2025 to 2026 — from 125 tags to 200 tags, a 60% increase. Type 7 tags doubled in the same period, growing from 25 to 50. Tag quota increases of this magnitude typically reflect either herd growth, a management shift toward higher harvest, or both. Hunters should take this into account when evaluating draw competition and expected future hunter pressure.
The unit's high-country character and 8% wilderness coverage make it a more demanding hunt than a classic plains antelope unit. Hunters who are physically prepared for elevation and rugged terrain will have a significant advantage. Those expecting to drive up to a fence line and shoot across a sagebrush flat should temper their expectations — this is mountain antelope country.
Bottom line: Unit 91 is a high-value draw target for pronghorn hunters who want a genuine combination of access, harvest probability, and trophy potential in backcountry terrain. For current draw odds and applicant data, visit the HuntPilot Unit 91 page.

Dates and fees are subject to change. Always verify current application details at the Wyoming Game and Fish Department website before applying.
Frequently Asked Questions
What is the terrain like in Wyoming Unit 91 for pronghorn hunting? Unit 91 is high-country terrain with elevations spanning from roughly 6,576 feet to over 13,000 feet across 440,855 acres. This is not the classic flat-basin antelope country found in many Wyoming units. Hunters should expect significant elevation change, rugged foothills, and a physical hunt. The 93% public land coverage means access is generally excellent, but the terrain demands physical preparation and the ability to pack out an animal in broken country.
What is the harvest success rate in Wyoming Unit 91 pronghorn? Recent data from HuntPilot shows success rates of 88% (2022, 429 hunters), 86% (2023, 66 hunters), 93% (2024, 75 hunters), and 94% (2025, 135 hunters). The four-year average sits near 90%, making this one of the higher-success pronghorn units in the state across a range of hunter pressure levels.
How big are the pronghorn in Wyoming Unit 91? The counties overlapping Unit 91 have a strong, documented history of producing trophy-class pronghorn. While this unit is not a pure meat-hunting destination, hunters targeting a true wall-hanger will find that the genetics and buck-to-doe ratio — averaging 55:100 across four survey years — support the presence of mature, quality bucks. Trophy potential in Unit 91 is strong relative to the broader Wyoming pronghorn landscape.
Is Wyoming Unit 91 worth applying for? For most pronghorn hunters, yes. The combination of 93% public land, near-90% historical harvest success, strong trophy history, and healthy herd demographics makes a compelling case. The main trade-offs are the high-country terrain (physically demanding compared to plains units) and draw competition that reflects the unit's quality. Tag quotas increased substantially from 2025 to 2026, which may affect future draw dynamics. For current draw odds and point requirements, check the HuntPilot Unit 91 page.
Can nonresident hunters do a DIY pronghorn hunt in Wyoming Unit 91? Yes — the vast majority of Unit 91 is fully accessible to nonresident DIY hunters. With 93% public land and only 8% of the unit designated as wilderness, approximately 92% of the acreage is open to self-guided nonresident hunting. Wyoming law requires nonresidents to use a licensed Wyoming outfitter only in designated wilderness areas, which represents a small fraction of this unit's total acreage. Physical fitness and backcountry competence are more significant factors here than outfitter requirements.
