An archaeologist who's been digging at the Topper Site in Allendale County for 11 years is uncovering new evidence that could rewrite America's history.

University of South Carolina archaeologist Albert Goodyear found artifacts at this rock quarry site near the Savannah River that indicate humans lived here 37,000 years before the Clovis people. History books say the Clovis were the first Americans and arrived here 13,000 years ago by walking across a land bridge from Asia.

Goodyear's discovery could prove otherwise.

His findings are controversial, opening scientific minds to the possibility of an even earlier pre-Clovis occupation of America.
