2CX) Quaternary Formations of Southern New Jersey. 



land below this level is essentially bare Cretaceous. About 

 Eatontown, the Cretaceous beneath the Cape May is sand, and 

 easily shifted by the wind. Eolian sand is here much in evidence 

 without being in great quantity. About Eatontown, the Cape 

 May formation is ill defined, and not more than 3 or 4 feet thick, 

 mostly sand. 



About Oceanport the relations are about as at Eatontown. A 

 few feet of sand, much of which looks as if it might be weathered 

 Cretaceous, overlies sands known to be Cretaceous. A little 

 gravel below the upper sand indicates that it is a surface accumu- 

 lation rather than a weathered mantle. 



From Oceanport to Long Branch, the Cape May formation 

 covers much of the surface below 40 to 50 feet, though no con- 

 tour line can be said to mark its limit; nor does it cover all the 

 surface at lower levels. Some of the valleys below the 40-foot 

 level appear to have been developed since its deposition, and 

 have been cut through it into Cretaceous beds below. Along 

 the shore, too, there is a margin of land made up of sand and 

 gravel younger than the Cape May — the modern beach deposits. 



The low but conspicuous little hills in the vicinity of Long 

 Branch at elevations of 60 to 70 feet are of Cretaceous sand. 

 Rising abruptly above their 20 to 30-foot surroundings, they 

 seem like considerable elevations. Over the lowlands there are 

 3 to 6 feet of sand, derived chiefly from the Cretaceous of the 

 vicinity. Some of it is eolian and underlain by a bit of gravel 

 ranging from a trace to a few inches in thickness. Nowhere in 

 the vicinity are there considerable beds of gravel referable to the 

 Cape May formation. There are beds of sand and g'ravel 20 

 to 30 feet thick along the beach, but they are recent. The beach 

 line is built against the mainland, instead of out from it, as 

 farther north. 



In the vicinity of West Long Branch, the following sections are 

 fairly typical : 



1. 3) 3 feet of compact fine gravel, sand and loam. 

 2) 1 foot greenish-brown loam. 

 1)1 foot loose gravel and sand, of Cape May type. 

 Cretaceous.
