156 Quaternary Formations of Southern New Jersey. 



Green Grove and farther north are much larger areas at eleva- 

 tions ranging from 130 feet down to 80 feet southeast of Hamil- 

 ton (Shark River village). West of Green Grove is a long 

 gravel patch, poorly exposed and indefinite, at 130 to 140 feet. 

 These gravels and sands at 120 to 130 feet, and at somewhat 

 lower levels near the sea, are perhaps Pensauken. 



The patches of gravel between Manasquan Valley and Shark 

 River are at various levels and are difficult of interpretation. 

 Back of Manasquan, there are gravels at 50 to 65 feet which 

 may be Pensauken. Similar areas occur farther north at Baileys 

 Corner, New Bedford, Glendola (Hopeville), and vicinity, and 

 reach a maximum elevation of a little more than 100 feet. These 

 gravels are much alike, are in similar topographic positions, and 

 are doubtless one in origin. They are unquestionably older than 

 the Cape May formation, and apparently harmonize with those 

 north of Shark River regarded as Pensauken. 



One to two miles west of Manasquan and Brielle, there is an 

 area of gravel (base 90 to 100 feet, surface 100 to no feet) 

 which is distinctly older than that at the lower level (50 to 65 

 feet) a mile to the northeast. The gravel of this higher area 

 is to be correlated with that on the divide just east of Allenwood, 

 with that a mile and more northeast of Allaire, and with that 

 in several small areas northwest of Glendola (Hopeville). The 

 gravels in these several places range up to 150 feet or so. They 

 seem to be rather low for Bridgeton, and too high for Pen- 

 sauken, but it is more probable that they belong with the former 

 than with the latter. 



Their correlation with the small gravel caps of the higher 

 isolated hills south and west of Wayside seems on the whole 

 most satisfactory, particularly since in both regions these areas 

 cap divides or isolated hills, and in both there are two series of 

 gravel deposits at lower levels. It follows from the above that 

 the large gravel areas northwest of Manasquan, at Baileys 

 Corner, near New Bedford, at Wall, and Glendola, are correlated 

 with the areas at Hamilton and the larger areas south and west 

 of Green Grove. Probably the gravel at Shark River station 

 and near Shafto's Corners belongs here also. All these are
