Summary:

Glacial outwash deposits in south-central Long Island, NY, are here named the Bellmore Formation. It consists of brown to yellow-brown, dense, cross-bedded sand and gravelly sand. Unconformably overlies the Wantagh Formation; forms the surficial sediment of much of south-central Long Island. Correlates with the Roslyn Drift of northern Long Island. Thickness at type section is 31.5 ft (9.6 m). Age is late Pleistocene (late Wisconsinan).

Summary:

Authors correlate the Harbor Hill Moraine with the Bellmore Formation, which overlies the Wantagh Formation. If the Wantagh proves to be Sangamonian, then the position of the Bellmore becomes early Wisconsinan.
