Wind Cave National Park
The Bison Range is in the northeast corner of the zoo, and has been a feature of the zoo since its opening. The range initially served to breed Plains bison, who were in danger of becoming extinct in the United States. Today, the exhibit continues to hold one of the few large herds of bison in U.S. zoos. In 1913, at the behest of the American Bison Society, fourteen bison were transported from the range to Montana's National Bison Range, as well as to Wind Cave National Park in South Dakota.
