Giants once roamed the Earth in our region. Mammoths and mastodons, elephant-like creatures, were common until humans hunted them to extinction.
Evidence of their presence can still be found, including mammoth tracks on a dry lake bed in Lake County (Oregon). University of Oregon paleontologist Gregory Retallack has been investigating the tracks, which indicate mammoths traveling in a group (and one might have been limping). Dr. Retallack shared his findingsin a new article; he visits with details.
