Abstract
A section of worked mammoth tusk reported to have been recovered but unrecognized as an artifact in January 1964 was actually discovered in November 1963 and recognized by several people at that time. The provenience for the tusk segment is given as unit B, which is declared to be pre-Clovis in age and more than 12,000 years old. The postulated translocation of the tusk, as well as other faunal remains and Clovis artifacts, is attributed to the influence of spring discharge and saturation of sediments. My salvage excavations in December 1963 and January 1964 are outlined, and my conclusions are not compatible with the concept of large-scale intrusion of artifacts and bones. The stratum designated as unit B in the north bank is entirely of Clovis age, and the mammoth-tusk artifact was coeval with its enclosing sediments.
