Figure 3. Generalized geologic map of the Inner New York Bight. Long Island is composed 



of Pleistocene glacial sediment overlying Cretaceous strata. The inferred offshore 



contact between Tertiary and Cretaceous strata is derived from Garrison (1970) 



and supported by ICONS data along the Long Island south shore.
