Hydrologic framework of Long Island, New York

Douglas A. Smolensky, Herbert T. Buxton, Peter K. Shernoff

1990, Hydrologic Atlas 709

Long Island, N.Y., is underlain by a mass of unconsolidated geologic deposits of clay, silt, sand, and gravel that overlie southward-sloping consolidated bedrock. These deposits are thinnest in northern Queens County (northwestern Long Island), where bedrock crops out, and increase to a maximum thickness of 2,000 ft in southeastern Long...
