Figure 5. Generalized geologic map created by combining previously published stratigraphic interpretations within the study area and new interpretation for western Massachusetts Bay. Data are modified from (A) Barnhardt and others, 2006; (B) Oldale and Bick, 1987; (C) Oldale and Wommack, 1987; (D) Hein and others, 2013; and (E) Oldale and others, 1994. The stratigraphic correlation of units in this map is shown in figure 6. The drumlins identified by Oldale and others (1994) in western Massachusetts Bay are outlined in gray.
