Ah, a common mistake of northerners. It's not a bone licker, but a lick containing big bones. Big Bone Lick was a favored destination of people like Meriwether Lewis, William Clark, George Rogers Clark, William Henry Harrison, Christopher Gist, and numerous others. Even Daniel Boone and Simon Kenton knew Big Bone Lick. The Lick was also the origin of the greatest escape-from-Indian-captivity epic which ever took place (Mary Draper Ingles), repeated, handed down, and held dear by all Kentuckians.
More than 12,000 years ago, Pleistocene mammals made their way into North America by way of Beringia, the ancient land mass between Asia and North America. This land bridge was exposed when the ocean water levels dropped as the two-mile thick glacier of that time developed. As the large animals made their way down to the now-Big Bone Lick area, they were followed by the Paleo Indians who depended on these animals for their subsistence (food, clothing, and shelter.)
The animals were drawn to the Lick for the salt, which resulted from ancient ocean water from another epoch trapped in the geologic anomalies below, which found their way to the surface, and the humans were drawn to the animals. So it continued, millennium after millennium, and the bones of these animals were deposited in and around the salt lick itself.
It all started, more or less, with the 1705 discovery of a fist-sized tooth in the Hudson River valley. After much debate, it was determined to be the tooth of a really, really large human, one of a race that existed before Noah and the Flood, and who was exterminated during the flood. Later, as more and more bones and teeth were discovered as explorers moved westward (Big Bone Lick was "discovered" by a Frenchman in 1739, after being told of its existence by the Native Americans), the fossils were thought to have been from an elephant-like mammal, eventually termed American Ingognitum.
Additional debates roiled on as to whether this animal was carnivorous or an herbivore, not to mention the religious and philosophical implications of all this mess.
Meanwhile, during all this fossil debating, a new America was having an identity crisis, you know, not having any kind of real history or ruins to draw pride from (because, well, the people who were already here, the Native Americans, their history was irrelevant, of course). However, it was Thomas Jefferson's relentless ambition to prove to snotty and snooty European philosophers and naturalists that the animals and native humans of America were not, in fact, inferior to those of their continent, but that they were indeed superior. This was the basis for writing his Notes on the State of Virginia.
The bones of the American Incognitum, therefore, became a source and identity of our national pride, and Big Bone Lick became world famous as the area for these highly treasured resources. Explorers, naturalists and scientists put Big Bone Lick at the top of their "Must Visit" lists.
These explorations and discoveries were going on at a time when the leading men of science worldwide had never even consider the possibility of extinction (gasp, the blasphemy) occurring in any species. Darwin's theory of evolution was a long time away. Lewis and Clark set out with specific instructions from President Thomas Jefferson to look for these huge mammals while out west. Since the concept of extinction was not yet known, Jefferson assumed these large mammals had simply migrated westward.
All of this happened years before the first dinosaur bone or even the concept of dinosaurs ever existed in this country. To have a place such as Big Bone Lick where the variety and sheer numbers of teeth and bones made it a source of national pride, intense study and debate.
So while the name invariably invokes the immature pubescent giggles of the Beavis and Butthead in us all, Big Bone Lick is a place with a rich history, and a place of discovery, awe and scientific wonder.
The unnatural proclivities of Dueling Banjos, et al, and more, certainly exists in Kentucky, but not so much in the western or central part of the state (where Big Bone Lick can be found). It's basically the area bound to the north by I-64, I-75 on the west, I-77 on the east, and I-81 to the south. Essentially a large square with Pikeville, KY at the center of it all. It's an area of the country where you don't want to wander around alone iffen you gots a purdy mowf and kin skweel like a pig.
