OSL (optically stimulated luminescence) dates on soils above ice age strata show pre-Clovis is at least older than 14,000.

May 2002 — Geologists find new profile showing ancient soil lying between Clovis and pre-Clovis, confirming the age of ice age soils between 16,000 - 20,000 years.

Using a backhoe and hand excavations, Goodyear's team dug through the Pleistocene terrace soil, some 4 meters below the ground surface.

Goodyear found a number of artifacts similar to the pre-Clovis forms he has excavated in recent years.

The findings are significant because they suggest that humans inhabited North America well before the last ice age more than 20,000 years ago, a potentially explosive revelation in American archaeology.
