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:
