The brown stain on his leg was his tarsal gland releasing his scent as he was in a rut (Rut refers to the deer mating season). The deer seemed as big as an average, measured from six to seven feet, and could weigh as much as 300 lbs (about 136 kg).
A photo was later shared by the Vilas County Sherriff's Office, which called the albino buck "an incredible sight to see". Plenty of commenters called the deer "majestic" and "stunning".
