He is also the founder and director of the Allendale Paleo Indian Expedition, a program that involves members of the public in helping to excavate Paleo American sites in the central Savannah River Valley of South Carolina.Goodyear earned his bachelor's degree in anthropology from the University of South Florida (1968), his master's degree in anthropology from the University of Arkansas and his doctorate in anthropology from Arizona State University (1976).The Topper excavation site is on the bank of the Savannah River on property owned by Clariant Corp., a chemical corporation headquartered near Basel, Switzerland.He recovered numerous stone tool artifacts in soils that were later dated by an outside team of geologists to be 16,000 years old.For five years, Goodyear continued to add artifacts and evidence that a pre-Clovis people existed, slowly eroding the long-held theory by archaeologists that man arrived in North America around 13,000 years ago.Last May, Goodyear dug even deeper to see whether man's existence extended further back in time.OSL (optically stimulated luminescence) dates on soils above ice age strata show pre-Clovis is at least older than 14,000.

May 1999 — Team of outside geologists led by Mike Waters, a researcher at Texas A&M, visit Topper site and propose a thorough geological study of locality."Topper is the oldest radiocarbon dated site in North America," Goodyear says."However, other early sites in Brazil and Chile, as well as a site in Oklahoma also suggest that humans were in the Western Hemisphere as early as 30,000 years ago to perhaps 60,000." In 1998, Goodyear, nationally known for his research on the ice age Paleo Indian cultures dug below the 13,000-year Clovis level at the Topper site and found unusual stone tools up to a meter deeper.Then on the last day of the last week of digging, Goodyear's team uncovered a black stain in the soil where artifacts lay, providing him the charcoal needed for radiocarbon dating. Tom Stafford of Stafford Laboratories in Boulder, Colo., came to Topper and collected charcoal samples for dating.

"Three radiocarbon dates were obtained from deep in the terrace at Topper with two dates of 50,300 and 51,700 on burnt plant remains.

One modern date related to an intrusion," Stafford says.
