White-tailed Jack Rabbit

     Lewis and Clark first saw white-tailed jack rabbits in what is now Lyman County. The white-tailed jack rabbit is a large hare. It prefers open areas where its keen hearing, good eyesight, and great speed make it easy to escape. They can move up to 40 miles per hour.

     "I measured the leaps of one and found them twenty-one feet. They appear to run with more ease and to bound with greater agility than any animal I ever saw."—Lewis’s journal, September 14, 1804
