We have been blessed to see so many wild animals in Theodore Roosevelt National Park, including American Bison, Black-tailed Prairie Dogs, wild Horses, wild Turkeys, and Big Horn Sheep—everything except for an elk which are rarely seen even by USNPS employees. The wild horse herds in the South Unit have ancestry dating back to the Wild West days of the late 1800s. Some say they are descendants of Crazy Horse’s herd, while others say their genetics are from the days in the late 1800s when ranches would turn horses loose, and catch and break them as needed. They look like pets, but are not at all docile.
