Tracy Weese spotted the deer as it strolled through her snow-covered yard in Boulder Junction on Sunday.
“His majesty just strolled through our backyard,” Weese wrote alongside the photos. She said the deer was an 11-point buck.
The Vilas County Sheriff's Office shared Weese's photo, calling the deer a "majestic creature."
It is illegal to shoot all-white deer in Wisconsin, since they are protected by the state.
According to the Wisconsin Department of Natural Resources, hunters are prohibited from shooting "albino and white deer which have a coat of all white hair except that the hair on the tarsal glands, head or parts of the head may be a color other than white."
