Comments
DkSl-VP, Windy Link Pot Cave: This cave is in an extensive karst, extending for nearly 10 km underground with several steep drops in the cave floor. Bear and deer bones found in the cave show no evidence of human butchering or carnivore tooth marks, and they are presumed to represent animals that fell into the cave. The uncorrected age is presented as a "conventional" date, presumably to distinguish it from an AMS date, and the normalized age is said to be a "corrected date."
