Pre-Clovis evidence at the Big Eddy: While all of this discussion has been very interesting and useful, it is not what has made the Big Eddy famous. The 1997 dig went to the base of the Clovis material, but deeper samples had revealed intriguing hints of even older occupations at lower levels. The team returned in 1999 with the intent of investigating those clues more thoroughly. What has been found may be some of the oldest artifacts ever found in North America, but they remain controversial due to the lack of clear human action on them.
