“…Other aspects of coastal plain geology are discussed by Sanford (1912) , Wentworth (1930) , Cederstrom (1941), Richards (1950), and the early literature is summarized by Ruble (1965). Harrison, et al (1965) presents evidence for a late Pleistocene uplift in the area.…”

This report is published to provide coastal engineers with a description of beach erosion and accretion at Virginia Beach, Virginia, including the effect of continuing beach replenishment, and the apparent unimportance of land use in determining erosion. This report also provides benchmark data on coastal processes at the shore north of the CERC Field Research Facility at Duck, North Carolina. The work was carried out under the beach evaluation program of the U.S. Army Coastal Engineering Research Center CCERC) The report was prepared by Victor Goldsmith (principal investigator) Susan Sturm, and George Thomas of the Virginia Institute of Marine Science (VIMS), Gloucester Point, Virginia, under CERC Contract No. DACW72-74-C-0008. Work under this contract is also reported in Applied Science and Ocean Engineering No. 122 of VIMS.

“…South of the LGM glacial ice margin, the coastal margins reflect a much milder climate. Both Emery et al (1967) and Harrison et al (1965) reported a freshwater peat from a core extracted from the continental shelf near the mouth of the Chesapeake Bay, which was dated to 18,398 ± 316 cal yr BP. Pollen data and macro-organic remains from this peat indicate the Middle Atlantic coastal forests were composed of grasslands and a variety of coniferous and deciduous arboreal species, such as spruce (Picea), pine (Pinus), fir (Abies), birch (Betula), alder (Alnus), and oak (Quercus).…”

“…Their analysis consisted of the identification of associated plant charcoal, pollen, and phytoliths from five paleosols dated to 42,000, 35,000, 30,000, 24,000, and 20, reinforced by the contemporaneously dated Columbian mammoth (Mammuthus columbi), a mild-adapted southern species, unearthed at the Inglewood site near Largo, Maryland (Haynes, n.d.;Karr 2015). Floral data for the Middle Atlantic coastal plain region are relatively scant for the period after 20,000 cal yr BP (see Emery et al 1967;Harrison et al 1965). Pollen from several locations suggests relatively mild conditions at or slightly before Clovis.…”

“…Pollen from several locations suggests relatively mild conditions at or slightly before Clovis. A freshwater peat dated to circa 13,500 cal yr BP from a core extracted near the mouth of the Chesapeake Bay (Harrison et al 1965) revealed pine, fir, birch, alder, spruce, willow, and oak pollen. A similar suite of pollen was noted for a roughly contemporaneous sample extracted at Duck Creek in Delaware (Kellogg and Custer 1994, 69-71).…”

This paper summarizes current evidence for earliest human occupation of northeastern North America during the late Pleistocene and early Holocene. We review evolution of the region's landscapes and evidence of archaeological chronologies as context for understanding human settlement of the region. Current data support limited evidence for pre-Clovis occupation south of the Laurentide glacial margin, followed by a significant temporal gap prior to early Paleoindian settlement of the region. Despite differences in subregional data sets, mapping of site distributions and assemblage data do support the notion of variation in lifeways between Paleoindian populations occupying formerly glaciated parts of the Northeast in the late Pleistocene, versus contemporary groups in lands south of the Laurentide glacial margin. Through time, the greatest differences in Paleoindian land use and technology occur between the Younger Dryas and early Holocene.

“…In recent years, however, several authors (6) have questioned the Pleistocene stability of the Chesapeake Bay area and the origin and correlation of the terraces. My palynological and geological investigations (7) of the terraces and terrace deposits in the District of Columbia and Maryland seem to support these doubts.…”
