Ronald Watson Gravel site (15 BE 249) - Credit: Wikimedia Commons
The Ronald Watson Gravel site (15BE249) is an archaeological site near Petersburg in Boone County, Kentucky, on an inside bend of a meander of the Ohio River. Excavations have determined that the site was occupied several times, during the Late Archaic, Middle Woodland, Late Woodland, and Middle Fort Ancient periods, although none of these are transitional occupations from one period to another. It is the best documented Middle Woodland site in the Northern Bluegrass region of Kentucky. Read more on Wikipedia
