Audits the age control at the 29 sites where proponents report the boundary layer. Several have no age control, others irrelevant ages or flawed age-depth interpolations; only 3 of 29 fall within the proponents' own window for the Younger Dryas onset.

The claimed layers are of different ages, or their ages are not known well enough to say.

Answer

ANS

Only 3 of the 29 claimed sites have age control placing the layer at the onset.

Evidence

EVD

Several claimed sites have no age control, nearly a dozen use flawed age-depth interpolations, and several…
