Unit 512 mule deer use high-elevation aspen basins and sage benches.

High Basins

How to Hunt Mule Deer in Unit 512

This is a quality hunt that deserves quality preparation.

Long-Range Glass

Spend more time behind optics than hiking. A 15x or 20x spotting scope locates bedded bucks at half a mile, saving legs for the actual stalk.

Stalk Discipline

Premium bucks survive because they are wary. Close the final 200-300 yards slowly, wind-first, and do not rush.

Aging Antlers

With a long points build, we do not settle for a young buck. Practice aging deer through glass before the hunt.
