Summary:
The term Sandy River diamicton replaces the Sandy River till of Caldwell (1959) and includes the Sandy River till equivalents discussed in this study. The informal term New Sharon till (Caldwell, 1959) is discontinued and the informal term New Sharon beds is proposed for the organic-bearing silt and gravel at New Sharon. The complex glaciogenic facies exposed at New Sharon have previously been interpreted to represent several glacial events separated by interglacial periods. This author, however, demonstrates that the units represent glaciolacustrine and glacial deposits from a single late Wisconsinan ice advance. The allochthonous New Sharon beds are separated from the overlying Sandy River diamicton by glacial Lake Caldwell and proglacial deposits.
