Mule deer occur across Wyoming wherever sagebrush, broken foothills, badlands, and open mountain forest meet. They are readily watched in the Red Desert and Green River Basin, around Thermopolis and the Bighorn Basin, in the Laramie foothills, and throughout western Wyoming. The famous Sublette herd migrates between high summer range and winter country in the upper Green River region.
The species is present all year, but seasonal movement can completely change local visibility. Dawn and dusk are productive, summer animals often use higher country, and autumn migration and the rut bring deer into open terrain. Highway viewers should be alert during migration; the mapped record total reflects access and reporting effort, not abundance alone.
