CO Elk Unit 66
AI Scout Preview
CO 66 — Tactical Analysis. Terrain & Access CO 66 spans 575,000 acres across a dramatic elevation range (7,158–14,274 ft), offering a mix of lower-country and high-country habitat. With 84% public land and 18% wilderness, the unit combines reasonable access via roaded terrain with significant backcountry opportunity for hunters willing to travel deeper. The high-elevation component makes this a unit where September conditions and early-season glassing from ridges can be productive, while the lower elevations provide fallback terrain as conditions change. Herd Quality Recent wildlife surveys indicate a below-average bull:cow ratio of 21:100, suggesting moderate harvest pressure..
