Colorado Unit 70 Mule Deer Hunting Guide

Colorado Unit 70 offers hunters a substantial opportunity for mule deer hunting across nearly one million acres of diverse terrain in south-central Colorado. This large unit spans elevations from 4,838 to 13,986 feet, encompassing everything from high desert valleys to alpine peaks. With 74% public land access and consistent harvest success rates in the mid-to-high 60% range, Unit 70 presents a compelling option for both resident and nonresident hunters seeking a quality mule deer experience.

The unit's sheer size—965,795 total acres—provides ample room for hunters to spread out and find their own hunting ground. Recent harvest data from HuntPilot shows the unit consistently supports over 1,000 successful hunters annually, with 2024 producing 1,719 harvested deer from 2,498 total hunters. This level of harvest activity combined with the unit's extensive public land base makes it an attractive destination for hunters who value opportunity over exclusivity.

HuntPilot Analysis

Unit 70 represents solid value for mule deer hunting, particularly for hunters prioritizing opportunity and access over trophy potential. The numbers tell a compelling story: harvest success rates have remained remarkably consistent, ranging from 66% to 70% over the past four seasons. This stability suggests a healthy deer population that can support sustained hunting pressure without experiencing dramatic fluctuations.

The unit's 74% public land composition is a significant advantage for DIY hunters. With only 3% designated wilderness, most of the huntable terrain remains accessible without guide requirements, making this unit particularly appealing for nonresident hunters planning unguided hunts. The elevation range of nearly 9,000 vertical feet provides diverse habitat types and hunting opportunities, from desert mule deer in the lower elevations to high-country bucks in the alpine zones.

Trophy potential in Unit 70 appears moderate based on available records. While the area has produced trophy-class animals historically, hunters should approach this unit with realistic expectations focused on opportunity rather than record-book potential. The consistent harvest numbers and success rates indicate this is fundamentally an opportunity unit where hunters can expect to see deer and have reasonable chances of filling tags, but trophy-class bucks will be the exception rather than the rule.

The 2024 wildlife survey data shows a buck-to-doe ratio of 33:100, which falls within normal ranges for a heavily hunted unit. This ratio suggests adequate buck recruitment to sustain the hunting opportunity, though hunters should expect to encounter more does and younger bucks than mature animals during their hunts.

Harvest Success Rates

Unit 70's harvest performance demonstrates remarkable consistency across recent seasons. In 2025, the unit hosted 1,531 hunters who harvested 1,014 deer for a 66% success rate. The previous year saw higher hunter numbers with 2,498 participants, resulting in 1,719 harvested deer and a 69% success rate.

The 2023 season produced similar results with 2,236 hunters achieving a 70% success rate by harvesting 1,574 deer. Even in 2022, with lower hunter numbers of 1,113, the unit maintained its reputation for consistent opportunity with 757 harvested deer and a 68% success rate.

This four-year track record shows success rates consistently in the mid-to-high 60% range, indicating a stable deer population that can support substantial hunting pressure. The variation in hunter numbers between years—ranging from just over 1,100 to nearly 2,500—suggests that tag allocations may fluctuate based on population assessments and management objectives, but the underlying success rates remain steady.

These harvest statistics position Unit 70 as a reliable choice for hunters seeking good odds of filling their tags. While success rates in the upper 60% range aren't exceptional by Colorado standards, they represent solid, dependable opportunity that many hunters will find attractive, especially given the unit's large size and abundant public access.

Trophy Quality

Counties overlapping Unit 70 have a strong history of trophy records, indicating that trophy-class mule deer have been taken from this area consistently over time. However, hunters should approach Unit 70 with measured expectations regarding trophy potential.

The unit's management emphasis appears focused on providing hunting opportunity rather than producing exceptional trophy animals. With harvest numbers regularly exceeding 1,000 deer annually and success rates in the upper 60% range, the hunting pressure and harvest levels suggest that most bucks are harvested before reaching trophy maturity.

Trophy production in the area appears to be episodic rather than consistent, with trophy-class animals representing a small percentage of the overall harvest. Hunters primarily seeking trophy opportunities would likely find better options in Colorado's limited-entry units with lower tag allocations and reduced hunting pressure.

That said, the unit's vast size and diverse habitat provide opportunities for hunters willing to work harder and venture into less accessible terrain. The elevation range from desert valleys to high alpine zones creates varied habitat conditions that can support different age classes of bucks, though finding mature animals will require dedication and knowledge of deer movement patterns.

Access & Terrain

Unit 70's 74% public land composition provides excellent access opportunities for DIY hunters. This substantial public land base, combined with the unit's minimal wilderness designation of just 3%, means most huntable terrain remains accessible to hunters without special requirements or guide services.

The unit's elevation range of 4,838 to 13,986 feet creates diverse hunting environments. Lower elevations feature high desert terrain with sagebrush, pinyon pine, and juniper habitats typical of Colorado's western slope country. As elevation increases, hunters encounter aspen groves, oak brush, and eventually subalpine fir and spruce forests at the highest elevations.

This topographic diversity means hunting conditions can vary dramatically within the unit boundaries. Desert valley floors may offer long-range shooting opportunities across open terrain, while timbered middle elevations provide stalking opportunities through dense cover. The high-country zones present alpine hunting challenges with spectacular scenery but also demanding physical conditions.

The unit's large size—nearly one million acres—ensures that hunters willing to explore can find areas with reduced hunting pressure. While easily accessible areas near major access points will see higher hunter concentrations, the vast public land base provides opportunities for hunters willing to hike further and work harder to find less pressured deer populations.

Weather conditions can vary significantly across the elevation range, particularly during later seasons. Hunters should prepare for potential snow at higher elevations even during early autumn hunts, while lower desert areas may remain warm and dry throughout the hunting seasons.

Herd Health & Population Trends

The 2024 wildlife survey data indicates a buck-to-doe ratio of 33:100 in Unit 70, which falls within typical ranges for Colorado's heavily hunted deer units. This ratio suggests adequate buck recruitment to maintain hunting opportunities, though it reflects the harvest pressure that limits the number of bucks surviving to older age classes.

Population trends appear stable based on the consistent harvest success rates and hunter numbers over recent seasons. The unit has supported harvest levels exceeding 1,000 deer annually while maintaining success rates in the upper 60% range, indicating that the deer population can sustain substantial hunting pressure without dramatic declines.

The variation in total hunter numbers between years—from 1,113 in 2022 to 2,498 in 2024—likely reflects Colorado Parks and Wildlife's adaptive management approach, adjusting tag allocations based on population assessments and habitat conditions. Despite these fluctuations in hunting pressure, success rates have remained relatively stable, suggesting underlying population health.

Long-term herd health in Unit 70 will depend on factors beyond hunting pressure, including habitat quality, weather patterns, and predation. The unit's diverse elevation range provides varied habitat conditions that can support deer populations during different seasonal periods, from winter range in lower elevations to summer range in high-country areas.

The buck-to-doe ratio, while not exceptional, indicates sufficient male recruitment to maintain breeding populations and provide hunting opportunity. However, hunters should expect to encounter more does and younger bucks than mature animals, reflecting the harvest pressure on older age classes.
