In an attempt to clarify the correlation between events marking the closing phases of the last glacial period in Europe and North America, radiocarbon ages of lignin and cellulose, separated from six wood samples from the Two Creeks forest bed, were carefully determined. The results were all within 140 years of 11,850 years B.P., suggesting that the forest is 450 years older than assumed previously. The new age opens the possibility of an intercontinental correlation of the Two Creeks forest with the Bölling instead of the Alleröd warm interval of Europe. It also denies correlation of the Two Creeks forest and the Champlain Sea.
