Yellowstone National Park
In 2003, the footprints of one female lynx and her child were found and followed for over . Feces and other material obtained was tested and confirmed to belong to a lynx. No one actually saw a lynx, however. Lynx have not been seen in Yellowstone since 1998, though DNA taken from hair samples showed that lynx were going through the park. Other mammals that are seen less often are the mountain lion and very few wolverines. There are about 25 mountain lions in the park.
