Big Bone Lick State Park is located at Big Bone in Boone County, Kentucky. It is located on Beaver Road and between the communities of Beaverlick and Rabbit Hash. The name of the park comes from the Pleistocene megafauna fossils found there. Mammoths are believed to have been drawn to this location by a salt lick deposited around sulphur springs. Ancestors of the sloth, bison, and horse also grazed the vegetation and salty earth around the springs that the animals relied on for their diet.
