Wyoming Unit 100 Elk Hunting Guide

Wyoming Unit 100 sits among the state's most talked-about elk units, drawing attention from hunters chasing both opportunity and consistent success. Spanning 2,392,607 acres with 74% public land, the unit offers substantial access for a state where private-land lockup is a real concern in many other areas. For hunters researching Wyoming Unit 100 elk hunting, the numbers tell a story of strong, reliable harvest performance combined with tightening tag availability — a combination that makes this unit worth a close look before committing points or planning a trip.

Elevation across the unit ranges from 6,100 to 8,642 feet, putting it in typical high-plains-to-foothill elk country rather than deep alpine terrain. With 0% wilderness designation, this is not a pack-in, guide-required unit — it's accessible country where DIY hunters can realistically plan and execute their own hunt, a point reinforced by hunter reports describing road-based access via oil and gas roads throughout the unit.

Harvest Success Rates

Unit 100 has produced some of the more consistent harvest numbers in Wyoming's elk units over the past several seasons. In 2022, 464 hunters combined for 391 elk harvested, a 84% success rate — an exceptional figure for any elk unit anywhere in the West. That success rate cooled slightly in following years but remained strong: 76% in 2023 (787 hunters, 596 harvested), 71% in 2024 (801 hunters, 566 harvested), and 74% in the 2025 season (573 hunters, 425 harvested).

What stands out across these four seasons is the combination of high hunter participation and sustained success well above 70% every single year. Few Wyoming elk units maintain that level of consistency across changing hunter pressure — participation swung from 464 hunters in 2022 to over 800 in 2024, yet success rates never dropped below 71%. That's a strong signal of a healthy, huntable elk population that isn't overly sensitive to hunter numbers, at least within the ranges seen in recent seasons.

Herd Health & Population Trends

Wildlife survey data collected across four survey years (2021-2024) shows an average bull:cow ratio of 51:100 for Unit 100. That ratio sits within a normal, believable range for a well-managed elk herd — it doesn't show the inflated numbers that typically flag a small survey sample, and it suggests a herd structure capable of producing mature bulls on a consistent basis without being overrun by tag pressure. A 51:100 ratio indicates enough bulls surviving to maturity to support both opportunity-focused hunts and hunters looking for older-age-class animals, though hunters should treat this as a multi-year average rather than a single-season snapshot.

Trophy Quality

Trophy records from the counties overlapping Unit 100 point to a moderate history of trophy-class elk production. This is not a unit defined by a heavy concentration of record-book entries, but trophy-class bulls have come from this general area over time. Hunters should keep in mind that these records are logged at the county level and are shared across all units overlapping those counties — the presence of trophy history in the region doesn't mean every bull taken in Unit 100 specifically contributed to those records, but it does indicate the genetic and habitat potential exists for mature bulls to develop here.

Given the bull:cow ratio and harvest consistency, Unit 100 appears capable of holding bulls into more mature age classes in pockets, even though it's better known as a numbers-and-success unit than a unit chasing exceptional record-book bulls every year.

Access & Terrain

At 74% public land, the large majority of Unit 100's 2,392,607 acres is open to hunters without needing to negotiate private landowner access — a significant advantage over many limited-entry Wyoming units where private ground dominates. With 0% wilderness, there's no state-mandated outfitter requirement here for nonresidents; this is a unit where a well-prepared DIY hunter can plan and execute a hunt independently.

That said, "accessible" doesn't mean easy. Multiple hunter accounts describe the unit as largely road-huntable via oil and gas roads, but caution that road conditions can turn rough fast when weather moves in. One hunter recommended bringing extra gas cans and at least two spare tires, noting that rain can shut down mobility across the unit entirely. This is remote, open country at elevations between 6,100 and 8,642 feet — sagebrush flats, rolling terrain, and long sightlines rather than dense timber. That terrain also cuts both ways for hunting strategy: forum reports describe seeing large concentrations of bulls with no cows in one part of the unit, and separately a herd of 400-plus cows elsewhere, underscoring that elk distribution can be patchy and locating breeding groups takes legwork even in a productive unit. Because the unit is road-accessible in many areas, hunters should also expect competition — one report specifically flagged that "too many guys" post up on known good spots right at first light, which argues for scouting off the beaten path rather than relying on the first pullout that looks promising.

HuntPilot Analysis: Is Unit 100 Worth Applying For?

Based on the data available through HuntPilot, Unit 100 earns a strong recommendation for hunters prioritizing success rate and access over trophy potential. The four-year harvest trend — never dipping below 71% success even as hunter numbers nearly doubled — is one of the more compelling success patterns among Wyoming's higher-volume elk units. Combined with 74% public land and no wilderness restrictions, this is a unit where nonresidents can plan a legitimate DIY hunt without hiring an outfitter.

The tag quota trends, however, deserve careful attention before applying. Type 4 tags were cut from 175 in 2024 to 100 in 2025, and again to 75 in 2026 — a 25% reduction in that final cut and a much steeper decline from the 2024 baseline. Type 5 tags fell even harder: from 250 in 2024 to 150 in 2025, then to just 75 in 2026, a 50% cut in the most recent adjustment alone. Type 1 (200 tags), Type 2 (100 tags), and Type 7 (25 tags) have all held steady across the same period. Hunters chasing Type 4 or Type 5 tags should recognize that opportunity in this unit is shrinking quickly, while Types 1, 2, and 7 offer more predictable tag availability going forward.

For hunters weighing whether to invest points or apply fresh, Unit 100 makes the most sense for those who value a realistic shot at filling a tag on accessible public land, backed by a herd structure that isn't showing signs of stress. Trophy hunters chasing a wall-hanger every season should keep expectations tempered — the moderate trophy history here suggests occasional quality bulls rather than a unit built around consistently exceptional record-book production.

Frequently Asked Questions

What is the terrain like in Wyoming Unit 100? Unit 100 sits at elevations between 6,100 and 8,642 feet, characterized by open, rolling country rather than dense timber. Hunter reports describe the unit as largely road-accessible via oil and gas roads, making it one of the more approachable Wyoming elk units for DIY access. With 0% wilderness designation, there's no guide requirement for nonresidents, but weather can quickly make roads impassable, and hunters should be prepared with extra fuel and tire capacity when venturing into remote sections.

What is harvest success like in Unit 100? Harvest success has been strong and consistent in recent seasons: 74% in 2025, 71% in 2024, 76% in 2023, and 84% in 2022. This success has held up even as hunter participation nearly doubled between 2022 and 2024, suggesting a robust elk population capable of supporting increased pressure without a major drop in success rates.

How big are the elk in Unit 100? Trophy records from the counties overlapping Unit 100 show a moderate history of trophy-class elk production, meaning quality bulls have come from the broader area but the unit isn't known for producing an outsized number of exceptional record-book animals. Combined with a bull:cow ratio averaging 51:100 across recent survey years, the herd structure supports mature bulls in the mix, though hunters should set realistic expectations rather than count on trophy-caliber results every season.

Is Wyoming Unit 100 worth applying for? Based on available harvest and access data, yes — particularly for hunters prioritizing a realistic chance at filling a tag over chasing a trophy wall-hanger. Success rates above 70% in four consecutive seasons, combined with 74% public land and no wilderness-related guide requirement, make this a strong candidate for DIY-minded elk hunters. Hunters should note that Type 4 and Type 5 tag quotas have been cut significantly heading into 2026, so tag type matters when deciding how to apply.

Are there tag availability concerns in Unit 100? Yes. Type 4 tags dropped from 175 in 2024 to 100 in 2025 and 75 in 2026, while Type 5 tags fell from 250 in 2024 to 150 in 2025 and just 75 in 2026 — a 50% cut in that final year alone. Type 1, Type 2, and Type 7 tags have remained stable across the same period, making them a more predictable option for hunters planning multi-year applications.
