The gray wolf gets its name from the thick, gray fur coat covering its body. While most wolves are gray, their coats can range in color from reddish to solid black. All of these color variations have been observed in Voyageurs' wolves. On average, adults are 5-6 feet in length, with females weighing 50-85 lbs. and males weighing 70-110 lbs. Their large feet make tracks 4.5' long by 3.5' wide, which are larger than similar looking tracks made by coyotes.
