CO Elk Unit 31

CO 31 — Tactical Analysis. Terrain & Access CO 31 spans roughly 449,000 acres across a substantial elevation range (4,700–9,050 ft), with mixed lower-country and high-country habitat. Public land comprises 63% of the unit, providing solid opportunity for DIY access without mandatory outfitter requirements. The elevation spread allows hunters to adapt to seasonal conditions — early-season hunting in lower drainages, later pursuits at higher elevations as animals shift. Herd Quality Recent wildlife surveys show an average bull:cow ratio of 23:100 across multiple years. This is a below-average herd composition, indicating consistent harvest pressure on the bull population..
