White-tailed deer in Wyoming lean toward the state’s river-bottom and prairie-edge country rather than the high alpine terrain mule deer favor, and Devils Tower National Monument carries far and away the strongest record here, 30 named sightings against 10 at Yellowstone and 6 at Grand Teton, tracing the cottonwood corridors and mixed woodland of the state’s northeast corner.
Records peak sharply in July, more than three times the January low, tracking the height of summer visitor traffic and fawns becoming mobile enough to be spotted alongside does. NatureServe rates the species secure (S5) both statewide and across its full range, and its clear preference for lower, brushier ground makes the Black Hills-adjacent terrain around Devils Tower a genuinely different Wyoming habitat than the high country most other ungulates on this list depend on.
