Stone tools offer new insights into first Oregonians

The UO's archaeological field school, operated by the Museum of Natural and Cultural History, returned to the Paisley Caves, under Jenkins' direction, in 2002 to test conclusions made by UO anthropologist Luther Cressman. Based on discoveries of artifacts he found in the caves in 1938-1940, Cressman claimed he'd found evidence of Pleistocene occupation by humans. That claim, based on technologies at the time, was not readily accepted. He died in April 1994, still claiming that he had proven his case.
