Season established to reduce disturbance of ungulates on their winter range-
Antlers and some horns (such as bighorn) are very valuable. There a quite a few “horn hunters” — people who gather them after they have fallen. As a result, there is competition and an incentive to get into the wintering grounds early, often when the animals are still wintering. So the Commission has a season. The horn hunters must wait until April 1 in areas west of the Continental Divide in Wyoming.
