CO Mule Deer Unit 66

CO 66 — Tactical Analysis. Terrain & Access CO 66 spans 575,000 acres across high-elevation Colorado terrain (7,158–14,274 ft), with 84% public land and 18% wilderness. This mix of national forest and BLM creates legitimate backcountry opportunity for self-reliant hunters willing to move into higher terrain, though access requires navigation of the unit's wilderness constraints. Elevation variation supports diverse habitat from lower timbered slopes to alpine basins—typical San Juan and Elk Mountain country with good glassing terrain at mid-to-high elevations. Herd Quality The recent mule deer population shows an above-average buck:doe ratio of 37:100, indicating solid breeding..
