The extent of fine-grained, detrital, organic accumulation in the basin, inferred from  sediment and pollen stratigraphies, varied over time and indicates low water levels  between 11,200 and 8000 cal yr B.P. and from ca. 5300 to 3200 cal yr B.P. This history  is consistent with the paleohydrology records from nearby Makepeace Cedar Swamp and  other sites from New England and eastern Canada and with temporal patterns of regional  changes in effective soil moisture inferred from pollen data. The similarities among  these records indicate that (1) regional conditions were drier than today when  white pine (Pinus strobus) grew abundantly in southern New England (11,200 to 9500  cal yr B.P.); (2) higher moisture levels existed between 8000 and 5500 cal yr B.P.,  possibly caused by increased meridonal circulation as the influence of the Laurentide  ice sheet waned; and (3) drier conditions possibly contributed to the regional decline  in hemlock (Tsuga) abundances at 5300 cal yr B.P. Although sea-level rise may have been  an influence, moist climatic conditions during the late Holocene were the primary reason  for a dramatic rise in water-table elevations.","author":null,"citation":"Shuman, B., J.
