MARTIN, S.C. At a depth of about four feet, 13,000-year-old artifacts emerge from the floor of a hole known as HS-N207E66 in such dense profusion that they leave the volunteers little room to work.

Like others who've dug here since the 1980s, the crew assigned to HS-N207E66 has reached the Clovis layer at the Topper-Allendale archeological site. Excavations there tell different versions of the same story: Near the end of the last ice age, America's first great artisans came to this hillside to quarry a prized stone tool-making material called chert. The artifacts suggest the intense period of Clovis-era activity begins a few centuries before 11,000 B.C. and fades away roughly 500 years later.
