New Mexico Unit 45 Mule Deer Hunting Guide

New Mexico Unit 45 mule deer hunting draws consistent interest from resident and nonresident hunters alike, thanks to a large footprint of public land, rugged high-country terrain, and a reputation among backcountry hunters as a unit that demands real physical effort but rewards those willing to put in the miles. Spanning elevations from 5,590 feet up to 13,042 feet across 974,580 total acres, Unit 45 offers one of the more dramatic vertical profiles available to mule deer hunters in the state.

With 82% of the unit classified as public land and 23% designated wilderness, Unit 45 is fundamentally a backcountry hunt. This isn't a unit where hunters glass from a truck window — the forum chatter around Unit 45 consistently references horses, spike camps, and long hikes as the price of entry, and the terrain data backs that up. For hunters willing to trade convenience for solitude and a shot at mature bucks in country that sees real hunting pressure only in pockets, Unit 45 deserves a hard look.

HuntPilot Analysis: Is Unit 45 Worth Applying For?

Unit 45 is a legitimate option for hunters who want public-land access without needing to draw an ultra-limited, multi-year point unit — but it comes with real trade-offs that hunters need to understand before applying.

On the positive side, the numbers are solid. In 2024, 877 hunters pursued deer in Unit 45 and 271 tagged out, a 31% success rate — up from 28% in 2022 when 860 hunters harvested 245 animals. That's a meaningful improvement year over year and suggests a herd and hunting pressure balance that's trending in the right direction rather than declining. A success rate in the low 30s for a general public-land mule deer unit is respectable, especially in a unit this rugged.

The catch is access and effort. With 23% of the unit locked up as wilderness, a substantial chunk of Unit 45's best country is foot-and-horse-only. Forum accounts from hunters who've worked this unit repeatedly emphasize that packing an animal out of the deep wilderness terrain is a serious physical undertaking — one hunter described it as requiring "horses, horses, and horses" after multiple seasons in the unit. That's a meaningful consideration for hunters without stock or without the conditioning to backpack deep into steep, high-elevation country.

Trophy potential is the other piece of the puzzle, and here the data is more measured. The counties overlapping Unit 45 show a limited history of trophy-class record entries. That doesn't mean quality bucks aren't present — the unit is large, high, and rugged, with plenty of the kind of terrain mature deer favor — but hunters should not go into Unit 45 expecting it to be a proven trophy factory based on historical record-book data. This is a unit better sold on opportunity, solitude, and rugged public-land access than on a documented trophy pedigree.

Given New Mexico's pure lottery draw system, there's also no point-building strategy to worry about here — every application is an independent draw, so hunters can apply opportunistically without needing to bank years of points first.

Bottom line: Unit 45 is worth applying for if hunters value big public land, don't mind demanding terrain, and are realistic about trophy expectations. It's less attractive for hunters seeking an easy, low-effort hunt or those chasing documented trophy genetics.

Access & Terrain

Unit 45's terrain is its defining characteristic. Elevations range from 5,590 feet at the low end to 13,042 feet at the highest points — a spread of nearly 7,500 vertical feet within a single unit. That range means hunters can encounter everything from lower foothill country to true alpine terrain, and deer distribution likely shifts significantly with elevation and weather as the season progresses.

Public land access is strong at 82%, which puts the vast majority of the unit's acreage in play for DIY hunters without needing to negotiate private land access. However, the 23% wilderness designation is a critical planning factor. Wilderness regulations prohibit motorized and mechanized access — no UTVs, no e-bikes — inside those boundaries, meaning hunters hoping to use vehicles to cover ground will find their options limited to the non-wilderness portions of the unit. Forum posts confirm this reality directly, with hunters noting that UTVs can extend access into the front country but can't be used once inside the wilderness boundary.

For hunters planning a trip, this suggests a two-tiered strategy: use vehicle or UTV access to scout and hunt the non-wilderness public land efficiently, while reserving pack-in efforts (on foot or horseback) for the deeper wilderness country where pressure is lower. Given the physical accounts shared by unit veterans — including warnents about the difficulty of packing meat out of the wilderness interior — hunters without horses should have a realistic plan for meat recovery before committing to a deep-country hunt.

Camp logistics also deserve some thought. Some hunters have brought larger RVs and set up as a base camp, while others opt for spike camps to stay closer to where they're hunting. Given the terrain's ruggedness and the distances involved in reaching the better country, a hybrid approach — a comfortable base camp for logistics with the option to push into a spike camp when conditions warrant — appears to be a common and practical strategy among hunters who've worked this unit before.

Trophy Quality

Trophy data for Unit 45 shows a limited history of record-book entries in the counties overlapping this unit. This suggests that while the unit certainly holds mature bucks given its size, elevation diversity, and wilderness component, it has not historically produced a strong volume of documented trophy-class deer compared to some other New Mexico units.

Hunters should treat Unit 45 as a solid opportunity unit rather than a unit chosen specifically to chase record-book genetics. That said, record-book data reflects only animals that were scored and entered — plenty of mature bucks go unentered every year, particularly out of rugged, low-pressure wilderness country where recovery and packing challenges may discourage some hunters from pushing into the areas most likely to hold older-age-class deer. Hunters focused on trophy potential should weigh this limited documented history against the unit's remote terrain, which does favor deer survival to maturity in the areas fewest hunters are willing or able to reach.

Harvest Success Rates

Unit 45's harvest numbers give hunters a clear, data-backed picture of what to expect. In the 2024 season, 877 hunters harvested 271 deer for a 31% success rate. That's an improvement from 2022, when 860 hunters recorded 245 harvests for a 28% success rate.

Two data points don't establish a long-term trend, but the direction is encouraging — success rates moved up three percentage points while hunter numbers held roughly steady (877 vs. 860). This indicates the deer population and/or hunter effectiveness improved slightly over that span rather than success being diluted by a jump in hunting pressure. For a unit this large and this vertically diverse, a success rate in the low 30s is a reasonably strong outcome, particularly for hunters willing to get away from easy access points and into the harder-to-reach public and wilderness terrain that likely sees less pressure.

How to Apply

Unit 45 deer tags are allocated through New Mexico's draw system, and hunters need to understand there are no preference or bonus points in New Mexico — every application, whether a hunter's first or fifteenth, has identical odds within its applicant pool. Résidents, nonresidents, and outfitter-guided applicants draw from separate pools, which is why nonresident tag fees and structures differ from resident allocations, but this separation is a pool cap, not a points system.

Because New Mexico's draw is a true lottery with no points to bank, hunters should apply every year they intend to hunt rather than waiting to "build up" toward a future application — there's nothing to build. The only real strategic lever is which hunt choices are listed on the application, since New Mexico allows multiple ranked choices per application.

Dates and fees are subject to change. Always verify current application details at the state wildlife agency website, or check HuntPilot's New Mexico state page (/states/nm) for updated application windows and unit-specific information before applying.

Frequently Asked Questions

What is the terrain like in Unit 45? Unit 45 covers a massive elevation range from 5,590 feet up to 13,042 feet across nearly 975,000 acres, with 82% of that land classified as public and 23% designated wilderness. That combination means hunters will find everything from accessible foothill terrain to serious high-alpine backcountry. The wilderness component in particular is known among hunters who've worked the unit for its remoteness and the physical demand of packing animals out, with several forum accounts specifically citing the need for horses to handle elk recovery from the deepest country — a consideration that applies similarly to deer hunters working the same terrain.

What is harvest success like in Unit 45? Recent data shows harvest success trending upward — 31% in 2024 (877 hunters, 271 harvested) compared to 28% in 2022 (860 hunters, 245 harvested). That's a solid success rate for a large, rugged public-land unit and suggests stable or improving conditions for hunters willing to put in the effort required by the terrain.

How big are the mule deer in Unit 45? Trophy record data for the counties overlapping Unit 45 shows a limited history of documented trophy-class bucks. This doesn't rule out mature deer being present, especially in the more remote wilderness sections that see less hunting pressure, but hunters shouldn't select this unit specifically chasing a proven record-book pedigree. It's better approached as a solid opportunity unit with a realistic — not exceptional — trophy ceiling based on available data.

Is Unit 45 worth applying for? For hunters who want big public-land acreage (82%), don't mind demanding wilderness terrain, and are comfortable with New Mexico's lottery-style draw where every application carries equal odds, yes — Unit 45 is a reasonable choice with a respectable and improving harvest success rate. Hunters primarily chasing documented trophy genetics or those unwilling/unable to handle rugged, high-elevation backcountry access should weigh those factors carefully, since a meaningful share of the unit's best country lies in wilderness terrain that limits motorized access and complicates meat recovery.

Do I need horses or a UTV to hunt Unit 45 effectively? Neither is strictly required, but both offer real advantages. A UTV can extend access efficiently through the 77% of the unit outside wilderness boundaries, though it cannot be used once inside the 23% wilderness area, where all travel must be on foot or horseback. Multiple hunters who've worked this unit repeatedly cite horses as close to essential for accessing and packing out of the deepest wilderness terrain, particularly at the higher elevations near the unit's 13,042-foot ceiling. Hunters without stock access can still hunt effectively by focusing on the substantial non-wilderness public land and by being realistic about how far they can pack an animal on foot.
