Peteet, D.M., J.S. Vogel, D.E. Nelson, J.R. Southon, R.J. Nickmann, and L.E. Heusser, 1990: Younger Dryas climatic reversal in northeastern USA? AMS ages for an old problem. Quat. Res., 33, 219-230, doi:10.1016/0033-5894(90)90020-L.

Late-glacial macrofossils from a 10-m core from Alpine Swamp, New Jersey, were radiocarbon dated using accelerator mass spectrometry (AMS). The arrival of the first tress to the area following deglaciation is indicated by maximum percentages of spruce pollen and a date of 12290±440 yr B.P. on a single spruce needle. Subsequent spread of deciduous hardwoods was followed by the exapnsion of boreal taxa, including spruce (Picea), fir (Abies), larch (Larix laricina), paper birch (Betula papyrifera), and alder (Alnus). Three AMS dates on paper birch seeds and a spruce needle during this boreal expansion indicate that it took place between 11000 and 10000 yr B.P. The timing of this vegetational shift and its correlation with late-glacial pollen stratigraphy from many sites in southern New England indicate that a climatic reversal correlative with the Younger Dryas characterized the North Atlantic seaboard of the United States.
