CO Elk Unit 521

CO 521 Tactical Analysis. Terrain & Access CO 521 spans 5,378 to 12,996 feet across nearly 325,000 acres of predominantly public land (77.4%), offering diverse elevation-driven hunting from lower-country timber through alpine basins. With 13% designated wilderness, most terrain remains road-accessible, though higher elevations demand pack-in effort. The unit's broad elevation range supports habitat transitions from valley floors to high-country parks—terrain selection is possible for hunters comfortable with scouting. Herd Quality Recent wildlife surveys show an average bull:cow ratio of 28:100—a well-managed, average herd composition. This indicates sustainable harvest pressure and a balanced age structure.
