Today’s forecast: I can’t feel my face. Just keep walking. During the winter, bison develop thick, woolly coats that help protect them from freezing temperatures and harsh winds. It’s said that a bison’s winter coat is so thick and provides insulation so effective that when snow accumulates on its coat, it will not melt from the heat of the bison’s skin. Their skin also thickens in response to cold temperatures and fatty deposits appear to insulate the animal. Same. Want to take a picture of these fuzzy creatures? Keep a safe distance and use your zoom to avoid the cold shoulder…literally. It will hurt when they lower it into you. Video: The cold never bothered this bison.
