22. Musk Ox
As prehistoric beasts that survived the Pleistocene extinction, Musk oxen would have landed much higher on the list, but you’re about as likely to run into one as you are a wooly mammoth. Musk oxen vanished from Alaska by the early 20th Century, only to be reintroduced in 1930. Today, these huge, hairy beasts are rare, and live in remote parts of the state rarely visited by humans.
