Abstract

Palynological analyses of 2 sediment cores, one 2.4 m long from northern Delaware, dated about 16,300 to 14,700 C 14 yr B.P., and one 1.8 m long from New Jersey just south of the Wisconsinan terminal moraine and dated about 13,600 to 12,500 C 14 yr B.P., give the first detailed evidence of vegetation in this area during these periods. The overall assemblages are similar to each other, with Picea and Pinus dominating the arboreal pollen and Poaceae and Cyperaceace the herbaceous flora. Nonarboreal pollen contributes about 30-50% of the total, indicating a very open vegetation. The persistence of the assemblages suggests stable and cold climate during this time of glacier retreat
