New evidence that an extraterrestrial collision
12,800 years ago triggered an abrupt climate
change for Earth, the Conversation, October 22, 2019

Carolina, contain a platinum anomaly,
pyrogenic carbon peak, and coprophilous
spore decline at 12.8 ka. Scientific Reports
volume 9, Article number: 15121 (2019)

Regardless of how the platinum anomaly is
interpreted, White Pond, a Carolina Bay predates
it and the Younger Dryas. Thus, the above paper
further supports the idea that the Carolina Bays
are not connected to Younger Dryas event as
concluded by:
