Colorado Bear Unit 421

Sightings, hotspots, and hunt insights for Colorado Game Management Unit 421.

Grand Mesa Unit 421 stacks more than 6,000 feet of vertical relief into one bear unit, from spruce-capped rim near 11,000 feet down to pinyon-juniper river breaks around 4,800 feet along the Colorado River. Bear hunters live in the Gambel oak mast and serviceberry benches of the mid-slopes, while the public ground funnels toward the mesa top and outer edges because the productive Plateau Creek and Buzzard Creek valleys sit mostly private. Our pack covers all of it: Unit Overview and Topography, Vegetation and Hydrology, Seasonal Expectations, Logistics and Access, and a one-page Essential Recon summary. Study the unit on our interactive map, then export the points you choose to onX or your favorite hunting map.

How this data was collected

Data Hunt Guide aggregates publicly available sighting reports from across the web (social media, hunting forums, harvest reports, and trail-camera shares) and uses a proprietary algorithm to identify high-activity zones (hotspots) within each unit. Our team verifies coordinates manually before publication.
