American bison (Bison bison) are the largest land mammals in North America; males, or bulls, can grow up to 8.2 feet tall at the shoulder and weigh up to 2,000 pounds, and their horns can grow to a maximum length of 2 feet. Bison have large, protruding shoulder humps made of massive neck muscles that help the animals shovel a path through deep winter snow with their horns. The massive mammals are also extremely fast and can reach a top speed of 35 mph, which is around three times faster than a human can run, according to NPS.
