Colorado Unit 46 Mule Deer Hunting Guide

Colorado Unit 46 is a high-country limited-quota unit spanning 136,443 acres, with elevations ranging from 7,731 feet to 14,234 feet. For mule deer hunters working through Colorado's draw system, Unit 46 represents a rugged, mostly public-land option where every hunt is allocated through limited-quota draw — there is no general season here, and hunters need to understand the application structure before building a strategy around this unit.

With 78% public land, Unit 46 offers substantial access for DIY hunters, and the 26% wilderness designation within its boundaries means a meaningful chunk of the unit demands backcountry fitness and genuine pack-in commitment. This is big, vertical country — the nearly 6,500 feet of elevation relief between valley floor and peak means hunters will find everything from sagebrush transition zones at lower elevations to alpine basins above timberline. That kind of terrain diversity typically spreads deer across multiple elevation bands depending on weather and time of year, which matters for anyone planning where to focus their effort.

Recent harvest data shows meaningful year-to-year variation in both hunter numbers and success, a pattern worth understanding before applying.

HuntPilot Analysis — Is Unit 46 Worth Applying For?

Unit 46 presents a mixed but intriguing picture. On the positive side, harvest success has been trending upward recently — the 2025 season produced a 45% success rate across 2,329 hunters, a notable jump from 29% in 2023 and 39% in 2024. That's a substantial swing, and it's worth noting that hunter numbers also spiked dramatically in 2025 (more than triple the 2024 total), which suggests either a significant increase in available tags or a shift in how hunts were structured that year. Hunters should treat the 2025 figures as a strong data point but not assume they represent a permanent new baseline — the 2022-2024 window, with hunter counts between 400 and 821 and success rates between 29% and 41%, may be more representative of typical conditions in a limited-quota unit like this.

The herd health picture is harder to read with confidence. The available survey data shows a buck:doe ratio of 28:100 from a single survey year (2024). A ratio that low is on the weaker end for a mule deer unit — for context, healthy mule deer herds typically run buck:doe ratios well above that. With only one year of survey data available, hunters should be cautious about drawing firm conclusions about herd structure or age-class distribution from this single snapshot, but the number itself doesn't suggest an abundance of mature bucks relative to the doe population at the time of the survey.

On trophy potential, the counties overlapping Unit 46 carry a moderate history of trophy-class record-book entries. That's a meaningful data point — it means trophy-class bucks have come from this broader geographic area over time, but production isn't at the elite or exceptional tier seen in Colorado's top-shelf mule deer units. Hunters chasing a genuine trophy animal should view Unit 46 as a unit with real but modest trophy potential, not a unit defined by consistent giant production. It's also worth remembering that record-book entries are logged by county, not by unit boundary, so any trophy history attributed to this area is shared with neighboring units that overlap the same counties — it doesn't mean those animals specifically came from within Unit 46's lines.

Taken together: Unit 46 is a legitimate consideration for hunters who value public land access (78%) and are prepared for strenuous, high-elevation terrain, and who are drawing a tag as part of a broader western hunting trip rather than chasing a specific giant. It's not a unit to burn a large stack of points on purely for trophy potential, given the moderate — not exceptional — trophy history and a single-year survey showing a modest buck:doe ratio. Hunters willing to do the physical work in wilderness-adjacent terrain, and who are realistic about success odds in the 30-45% range based on recent years, will find this a reasonable unit to apply for.

Harvest Success Rates

Unit 46's harvest data over the past four seasons tells a story of real variability:

• 2025: 2,329 hunters, 1,056 harvested — 45% success
• 2024: 752 hunters, 294 harvested — 39% success
• 2023: 821 hunters, 238 harvested — 29% success
• 2022: 400 hunters, 164 harvested — 41% success

The jump in both hunter participation and success rate in 2025 stands out. More than three times as many hunters pursued deer in this unit compared to 2024, and success climbed six points. This could reflect additional tags issued for that season, a change in hunt-code structure, or simply a strong year for deer movement and weather conditions that favored hunters. Whatever the cause, the 2022-2024 stretch — where hunter numbers stayed in the 400-820 range and success bounced between 29% and 41% — likely offers a more conservative baseline for planning purposes. Hunters should check HuntPilot's unit page for the most current year-over-year harvest trends before finalizing expectations, since a single outlier season can skew impressions of a unit's typical performance.

Trophy Quality

Trophy records tied to the counties overlapping Unit 46 reflect a moderate history of production. This means trophy-class bucks have come from this general area, but the frequency and caliber of entries don't place this region among Colorado's top trophy mule deer destinations. Hunters should treat Unit 46 as a unit offering a realistic shot at a mature, respectable buck rather than a unit with a strong recent track record of exceptional, record-caliber animals. Given the county-level nature of trophy data, it's also important to understand that any notable bucks attributed to this area could have been harvested in a neighboring unit sharing the same county lines — the data doesn't pinpoint harvest location within Unit 46 specifically.

Combined with the limited survey data showing a 28:100 buck:doe ratio in 2024, hunters focused purely on trophy potential should weigh Unit 46 against other units with stronger, more consistent trophy histories and healthier buck:doe ratios before committing points here.

Herd Health & Population Trends

The only wildlife survey data available for Unit 46 comes from a single year — 2024 — showing a buck:doe ratio of 28:100. This is a low ratio relative to what's generally considered a healthy, balanced mule deer population, and with just one year of data, it's impossible to establish a reliable trend. Hunters should be cautious about reading too much into a single survey year; herd composition data is most useful when compared across multiple years to identify whether a ratio is stable, improving, or declining.

Without additional years of survey history, the honest assessment is that Unit 46's buck:doe ratio data is limited, and the single available data point suggests a buck population on the thinner side relative to does. Hunters relying heavily on herd composition to judge trophy or age-class potential should treat this figure as a caution flag rather than a definitive statement about the unit's deer population, and should look to supplement it with scouting and more recent on-the-ground information closer to their hunt.

Access & Terrain

Unit 46 covers 136,443 acres with dramatic elevation change — from 7,731 feet at the lowest points to 14,234 feet at the highest, a span of more than 6,500 vertical feet. That range places the unit's upper terrain solidly in alpine territory, well above timberline, while lower elevations likely transition through timbered slopes into drier foothill and sagebrush country. Hunters should plan for serious physical demands if they intend to hunt the upper end of that elevation range, and should be prepared with appropriate conditioning and logistics for high-altitude backcountry work.

Public land accounts for 78% of the unit, which is a strong number and gives DIY hunters substantial room to operate without needing to negotiate private land access. That said, 26% of the unit falls within designated wilderness. In Colorado, wilderness designation does not carry the same guide requirements that nonresidents face in some other western states — nonresidents can hunt Colorado wilderness areas without hiring an outfitter. However, wilderness terrain by its nature restricts motorized access, meaning hunters planning to hunt the wilderness-designated portion of Unit 46 should expect foot or stock-based travel only, and should plan trips accordingly with extra time and physical preparation built in.

Given the elevation spread and wilderness percentage, Unit 46 rewards hunters who scout thoroughly and are comfortable covering ground on foot. Hunters can use HuntPilot's public land and terrain overlays to identify specific access points, elevation bands, and drainage systems within the unit's boundaries before heading out — this kind of unit benefits enormously from pre-season map study given the size and vertical relief involved.

How to Apply

Every mule deer hunt in Unit 46 is allocated through Colorado's limited-quota draw system — there is no general season or over-the-counter option available here. This means every hunter, resident or nonresident, must apply through the state's draw process to receive a tag for this unit.

Colorado's draw system uses a true preference point structure for deer, meaning the highest point holders in a given pool are awarded tags first, and a sufficient point total can effectively secure a tag in future draw cycles. Residents and nonresidents apply through separate pools, and nonresidents typically need a stronger point total to compete for the same hunts compared to residents. Because this is a preference-based system, points accumulated over years of unsuccessful applications meaningfully improve a hunter's position over time — unlike pure lottery states, strategic point-building is a legitimate approach in Colorado.

Hunters applying with few or no points should understand their draw odds for Unit 46 may be limited given its status as a fully limited-quota unit. It's also worth remembering that a successful draw consumes accumulated preference points, so hunters should weigh whether to use points now on Unit 46 or continue building toward a different unit with stronger trophy potential, depending on individual goals.

Application dates, fees, and point structures change with each draw cycle, so hunters should not rely on outdated information from past seasons.

Frequently Asked Questions

What is the terrain like in Colorado Unit 46? Unit 46 features dramatic elevation change, ranging from 7,731 feet to 14,234 feet across 136,443 acres. This includes lower-elevation transition terrain up through high alpine basins above timberline. With 78% public land and 26% wilderness designation, hunters have substantial access but should expect physically demanding conditions, particularly at higher elevations where motorized access is limited or nonexistent.

What is harvest success like in Unit 46? Harvest success has varied significantly in recent years, ranging from 29% in 2023 to 45% in 2025. The 2022-2024 period, with success rates between 29% and 41% and hunter numbers between 400 and 821, likely represents a more typical baseline than the unusually high-participation 2025 season. Hunters should check current data on HuntPilot before setting expectations.

How big are the mule deer in Unit 46? The counties overlapping Unit 46 have a moderate history of trophy-class record-book entries, meaning trophy bucks have come from the broader area but production isn't at an elite level. Hunters should view Unit 46 as offering a realistic chance at a mature buck rather than being known for consistent, exceptional trophy production. Specific trophy data for this unit is otherwise limited.

Is Unit 46 worth applying for? Unit 46 is a reasonable option for hunters prioritizing public land access (78%) and willing to handle rugged, high-elevation terrain, with recent success rates in the 29-45% range. It's less suited to hunters focused purely on trophy potential, given moderate — not exceptional — trophy history and a single survey year showing a low buck:doe ratio of 28:100. It's best suited to hunters seeking a solid backcountry deer hunting experience rather than those chasing a specific record-class animal.

Is there a general season option in Unit 46? No. Every mule deer hunt in Unit 46 is allocated through Colorado's limited-quota draw system. There is no general season or over-the-counter tag option for this unit — hunters must apply and draw a tag through the state's preference point system to hunt here.
