The Debra L. Friedkin site in Texas yielded 15,528 artifacts dating from 13,200 to 15,500 years ago.
Notes on verification
Directly confirmed by the original peer-reviewed Waters et al. 2011 Science paper, with matching figures corroborated by AAAS and other secondary sources. Some scholarly debate exists over interpretation (pre-Clovis vs. disturbed Clovis context), but the artifact count and date range are not disputed.
