Abstract

The AA. report six accelerator-mass spectrometer (AMS) 14C dates of hand-picked organic material from Ballybetagh. Several of the dates are based on terrestrial plant remains, thus eliminating the commonly encountered problem associated with Irish sites of errors due to the hard-water effect. The two most significant indicate that the Rumex-Salix zone, which represents the initial establishment of vegetation following deglaciation, began about 12,600 yr B. P. and the classic Younger Dryas began at 10,600 yr B. P., somewhat younger than the traditionally accepted age of 11,000 yr B. P.
