The Quaternary of New England

Seafloor character and sedimentary processes in eastern Long Island Sound and western Block Island Sound

“…The older of these sheets is commonly attributed to pre-to late Wisconsinan events, whereas the younger sheet is a product of the late Wisconsinan ice advance (Sirkin 1982). Two late Wisconsinan end-moraine lines cross Long Island (Schafer and Harshorn 1965;Sirkin 1982;Stone and Borns 1986). The Ronkonkoma moraine, which marks the maximum extent of the late Wisconsinan glaciation, lies across central and southeastern Long Island, and extends eastward across the shelf in the direction of Block Island.…”

An overview of Pleistocene and Holocene inland dunes in Georgia and the Carolinas: Morphology, distribution, age, and paleoclimate

“…Thorn (1967Thorn ( , 1970, from his work in northeastern South Carolina, thought that the relations States and calculated wind direction during the latest Pleistocene and early Holocene (between about 15 ka and 3 ka). Data from Hack, 1941;Olson 1958a;Schafer and Hartshorn, 1965;Daniels and others, 1969;Thorn, 1970;Ahlbrandt, 1973;Saucier, 1978; between dunes and bays indicated formation of dunes and bays by west-southwest and southwest winds, that locally dunes had modified some of the bays, and conversely that some bays had formed on dunal topography. He considered both dunes and bays to be less than 30 ka.…”

“…Microfloral assemblages from peat beds in the older dunes suggest that dune-forming events were synchronous with glacial maxima. Schafer and Hartshorn ( 1965) called the dunes in glacial Lake Hitchcock the most extensive in New England. The dunes lie on the eastern side of the Connecticut River on lake bottom, delta, and terrace sediments.…”

Surficial geologic map of the Norton-Manomet-Westport-Sconticut Neck 23-quadrangle area in southeast Massachusetts

“…Most of the surficial materials in Massachusetts are deposits of the last two continental ice sheets that covered all of New England in the latter part of the Pleistocene ice age (Schafer and Hartshorn, 1965;Oldale and others, 1982;Stone and Borns, 1986). In the southeastern region, the glacial deposits are divided into two broad categories, glacial till and glacial moraine deposits and glacial stratified deposits.…”
