The calibrated radiocarbon dates indicate human settlement started between 14,000-14,700 years B.P.[1] The site is claimed to contain evidence for the Younger Dryas impact hypothesis.[2] This evidence include sediment layers with charcoal and pollen assemblages both indicating major disturbances as well as rare metallic spherules, melt glass and nanodiamonds originating from claimed to be derivative of airbursts or impacts.[2] PaleontologyIn a 2007-2008 paleontological investigation 648 complete and fractured bones, 37 teeth, 11 coprolites, 348 wood pieces, 126 seeds, 28 skin and hair fragments were found. Further, 71 sediment samples were collected for analysis.[3] See also
