Summary:
Pg. 19-20. Cape May formation. Those deposits of late glacial and early postglacial time, which were made beyond region directly affected by the ice or its drainage. Includes much of loam which has heretofore been referred to under name "low-level Jamesburg." In places overlain by high-level loam, which in earlier reports was referred to under name "high level Jamesburg loam." Overlies Pensauken formation. Probably at least partly contemporaneous with drift of last [Wisconsin] glacial epoch. Covers whole of Cape May County, New Jersey. [Extends into southeastern Pennsylvania.]

Summary:
Pg. 5. Cape May formation. Apparently represents entire duration of the Pleistocene between last major interglacial and the Recent. At present, formation is divided into following zones or phases: (1) interglacial marine, sand and clay with warm water fauna, last major interglacial; (2) glacial marine, sand with cold-water fauna, early Wisconsin; (3) transitional, fine sand; and (4) fluvial, sand and gravel, Wisconsin and post-Wisconsin. Future work will probably show that term Cape May formation should not be used for all these phases. Studies made in excavations of Cape May Canal.

Summary:
Trenton Gravel (reinstated) replaces Cape May Formation of earlier workers in PA. Reference section for Trenton is pit at Penn Valley, Bucks Co., PA, where it consists of gray to pale-reddish-brown, very gravelly sand. Interbedded, cross-bedded sand and clay-silt layers. Deeply weathered; good aquifer; good sand for construction materials.
