Wyoming Unit 90 Mule Deer Hunting Guide

Wyoming Unit 90 is a mule deer hunting destination that draws attention from both resident and nonresident hunters looking for a mix of accessible public ground and consistent, if modest, harvest success. Spanning 827,156 acres with elevations ranging from 4,761 to 7,733 feet, this unit offers a broad cross-section of terrain — from lower-elevation sagebrush flats to higher benches and ridgelines that mule deer use seasonally. With 85% of the unit classified as public land, Unit 90 stands out as one of the more DIY-friendly mule deer units in Wyoming's draw system.

For hunters weighing whether to spend an application on Unit 90, the numbers tell a straightforward story: this is a unit with real opportunity, moderate trophy potential, and a harvest track record that's worth understanding before committing points or cash. This article breaks down what the data actually shows — success rates, herd trends, trophy quality, and the application process — so hunters can decide if Unit 90 deserves a spot on their hunt plan.

Harvest Success Rates

Recent harvest data for Unit 90 shows a unit that produces consistent, moderate success for hunters who draw a tag. In 2025, 50 hunters pursued mule deer in the unit and 25 tagged out, for a 50% success rate. The year before, in 2024, 51 hunters hunted the unit with 27 harvested, putting success at 53%.

That two-year average — hovering right around the 50-53% mark — indicates a unit where roughly half of hunters connect in a given year. That's a respectable number for a mule deer unit of this size and habitat diversity, but it also means hunters shouldn't expect a slam-dunk. Success in Unit 90 requires scouting, mobility, and a willingness to cover ground across varied terrain. The consistency between the two years (50% and 53%) suggests a stable hunt rather than one trending sharply up or down, which is a good sign for hunters trying to gauge what to expect before they ever set foot in the unit.

Trophy Quality

Trophy data for the counties overlapping Unit 90 points to moderate trophy potential. This isn't a unit with a heavy, decades-deep record of exceptional bucks, but it has produced trophy-class animals historically. Hunters should treat Unit 90 as a solid opportunity unit rather than a unit chased specifically for record-book-caliber bucks. That said, moderate trophy history combined with the unit's public land access and habitat diversity means mature bucks are present — patient hunters willing to glass extensively and pass on younger deer have a reasonable chance at a quality buck.

It's worth noting that record-book entries are logged at the county level, not the specific hunt unit, so the trophy history associated with Unit 90 is shared with neighboring units that overlap the same counties. This is standard across Wyoming's mule deer units and doesn't diminish the meaningfulness of the data — it simply means hunters should view trophy potential as a regional characteristic rather than a guarantee tied strictly to Unit 90's boundaries.

Herd Health & Population Trends

Wildlife survey data collected across four survey years (2021-2024) shows an average buck:doe ratio of 55:100 for Unit 90. This is a healthy, biologically realistic ratio for a wild mule deer population — well within the range expected for a functioning herd with a reasonable buck segment surviving to maturity. A 55:100 ratio doesn't suggest an exceptional or trophy-heavy herd, but it does indicate a stable population structure without signs of overharvest of the buck segment.

Hunters should read this ratio as a sign of herd health rather than an indicator of exceptional trophy potential — the two aren't the same thing. A stable buck:doe ratio in the mid-50s per 100 does support the moderate trophy assessment above: enough bucks are surviving to older age classes to produce quality animals, even if this isn't a unit known for producing a high volume of top-end trophies.

Access & Terrain

With 85% public land across 827,156 acres, Unit 90 is one of the more accessible mule deer units in Wyoming for DIY hunters. The absence of any wilderness designation (0%) means there are no additional access restrictions tied to Wyoming's outfitter-required wilderness law — nonresidents can hunt this unit without being required to hire a licensed guide, which is a meaningful advantage for hunters planning a self-guided trip.

The elevation range of 4,761 to 7,733 feet suggests a unit with meaningful topographic relief, likely encompassing lower sagebrush basins and foothill country transitioning into higher benches and ridges. This kind of terrain diversity typically supports mule deer seasonal movement between lower-elevation early-season habitat and higher ground later in the year. Hunters should expect a mix of open sagebrush country and rougher, broken terrain — conditions that reward hunters willing to glass long distances and put in physical effort to reach less-pressured pockets of public land.

Given the high percentage of public access, hunters can realistically plan a DIY hunt in Unit 90 without needing to secure private land permission, though as with any high-public-access unit, pressure on the most accessible ground can be a factor, particularly near main access points.

HuntPilot Analysis: Is Unit 90 Worth Applying For?

Based on the data available through HuntPilot, Unit 90 presents a reasonable case for hunters — particularly those prioritizing access and consistent opportunity over chasing an exceptional trophy. The harvest success rate sitting between 50-53% over the two most recent years is solid for a mule deer unit, and the 85% public land figure removes one of the biggest barriers DIY hunters face in the West: access.

The moderate trophy history means hunters shouldn't apply to Unit 90 expecting to consistently produce record-book bucks, but the herd health indicators — specifically the stable buck:doe ratio recorded across four survey years — suggest a functioning population capable of producing mature, respectable bucks for hunters willing to put in scouting time and pass on immature deer.

Where Unit 90 makes the most sense is for hunters who want a unit with genuine public-land opportunity, a fair shot at tagging out, and the possibility — not guarantee — of a quality buck. It's less suited to hunters whose sole objective is a wall-hanger; those hunters may want to look at units with a stronger, more concentrated trophy record. For everyone else — especially resident hunters and nonresidents building points who want a unit that rewards effort with a real chance at success — Unit 90 is a legitimate consideration.

Nonresidents should also factor in the meaningful cost difference between tag options in the 2026 application data, discussed below, since Wyoming offers multiple nonresident tag types with significantly different fees for Unit 90.

How to Apply

Wyoming's application system for deer, including Unit 90, runs through a structured calendar with specific open and deadline dates that hunters need to track closely.

For the 2028 application cycle, applications open January 5, 2028, with a deadline of March 1, 2028 for all regular applications.

For the 2026 Deer season, Wyoming's published application window opens January 2, 2026, with a deadline of June 1, 2026. There's also a separate point deadline of November 2, 2026 for hunters managing preference points outside the main application window.

Fee structures vary significantly by residency and tag type for 2026:

• Nonresident (Option 1): $15 application fee, $374 tag fee, $0.00 license fee (required to apply), $41 point fee
• Nonresident (Option 2): $15 application fee, $34 tag fee, $0.00 license fee (required to apply), $41 point fee
• Nonresident (Special/Premium tag): $15 application fee, $1,200 tag fee, $0.00 license fee (required to apply), $41 point fee
• Resident (Option 1): $5 application fee, $42 tag fee, $0.00 license fee (required to apply)
• Resident (Option 2): $5 application fee, $22 tag fee, $0.00 license fee (required to apply)

Note that Wyoming requires hunters to hold a qualifying license before applying — listed here at $0.00 for these categories — in addition to the application fee, tag fee, and, for nonresidents, the point fee. Nonresidents should pay close attention to the tag fee differences between the standard options ($34-$374) and the premium tag option ($1,200), as these represent very different cost commitments for the same draw system.

Wyoming residents building points for deer should track the November 2, 2026 point deadline separately from the main June 1, 2026 application deadline, since these serve different purposes in the draw process.

Frequently Asked Questions

What is the terrain like in Wyoming Unit 90? Unit 90 spans elevations from 4,761 to 7,733 feet across 827,156 acres, encompassing a mix of lower-elevation sagebrush country and higher benches and ridgelines. This elevation range supports seasonal mule deer movement between habitat types. With 85% public land and no wilderness designation, the terrain is generally accessible without requiring extensive backcountry travel, though hunters should expect to cover significant ground to find less-pressured areas.

What is harvest success in Unit 90? Recent data shows harvest success rates of 50% in 2025 (50 hunters, 25 harvested) and 53% in 2024 (51 hunters, 27 harvested). This consistency between years suggests a stable hunt where roughly half of hunters who draw a tag are successful.

How big are the mule deer in Unit 90? Trophy data for the counties overlapping Unit 90 indicates moderate trophy potential. The unit has produced trophy-class bucks historically, but it isn't known as a unit with a heavy concentration of exceptional, record-book-caliber deer. Hunters should approach Unit 90 as a solid opportunity unit where a stable buck:doe ratio (averaging 55:100 across four recent survey years) supports the presence of mature bucks, rather than as a unit specifically targeted for trophy hunting.

Is Unit 90 worth applying for? For hunters prioritizing access and reasonable odds of tagging out, yes — the combination of 85% public land, a 50-53% recent harvest success rate, and a healthy buck:doe ratio makes Unit 90 a solid, well-rounded option. Hunters chasing an exceptional trophy specifically may want to weigh Unit 90's moderate trophy history against other units with a more concentrated record before applying. Check HuntPilot's unit page for current draw odds to see how competitive the unit is for your residency and point status.

Does Unit 90 require a guide for nonresident hunters? No. Unit 90 has 0% wilderness designation, so Wyoming's outfitter-required law for wilderness hunting does not apply here. Nonresidents can hunt Unit 90 on a DIY basis without being required to hire a licensed Wyoming outfitter.
