Mule Deer Facts | Yosemite Wildlife Guide
They can be found in elevations ranging from 3,500 to 8,500 feet in the park, although they have been recorded near timberline, at over 10,000 feet.
Their annual migrations take them higher or lower depending on snowfall. They will typically stay as high as possible, until they reach an elevation where the snow is deeper than 18 inches, at which point it becomes difficult for them to feed.
Although mule deer are often described as more “laid back” and less jittery than whitetail deer, they should still be treated with respect and given their distance. More visitors to Yosemite have been injured by mule deer than by bears!
