Big Bone Lick State Park is located at Big Bone in Boone County, Kentucky. 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. It bills itself as “the birthplace of American paleontology,” a term which dates from the 1807 expedition by William Clark undertaken at the direction of President Thomas Jefferson.
