Since early May, amateur archaeologists have joined professionals in an ongoing excavation of a site in western Allendale Coun­ty, S.C., that apparently was called home by humans in the Ice Age .

It’s a summer camp of sorts for the amateurs, who paid $466 for a week of working with researchers from the University of South Caro­lina’s Institute of Archaeology and Anthropology, as part of the Al­lendale Paleoamerican Expe­dition. The last of five digs starts today at the site on the Savannah River just south of Martin .

Participants learn excavation techniques and how to identify artifacts. They camp near the dig and work from 8:30 a.m. to 4 p.m. each day.

The site, discovered in 1998, is on the property of Clariant Corp ., a manufacturer of chemicals . The location, named the Topper Site, is one of several in the eastern United States to produce evidence that humans lived in the West­ern Hemisphere during the last Ice Age, 16,000 or more years ago. That is 2,000 to 3,000 years earlier than scientists previously thought.
