Cape May Formation — Local Details. 187 



Pompeston Creek show that the Delaware here was filled up to 

 the level of about 40 feet. 



Pensauken Creek. — r The Cape May deposits of this valley con- 

 nect with contemporaneous deposits of the Delaware at Palmyra, 

 and are continuous up to Mount Laurel and Cropwell. Their 

 great expansion in area is between Moorestown and Mount 

 Laurel, over the broad tract of lowland in this region. 



Xear Xorth Pennsville there are feeble terraces, and they are 

 continued for a mile or more to the east; but the depth of the 

 Cape May deposits is slight, and they do not appear to corres- 

 pond with the level to which the Delaware was filled in this 

 epoch. They are probably remnants of plains of degradation 

 developed after the Cape May epoch. 



Up to the junction of the North and South branches of Pen- 

 sauken Creek distinct terraces have little development; but 

 between the Xorth and South branches the formation is well seen, 

 consisting of loose gravel and sand, rising to the 20^-25 foot 

 level. 



Along the North Branch, between Lenola Station and Perry, 

 there are many sharply defined bench-like areas at 20-30 feet, 

 which have a thin covering of Cape May material; but along 

 this branch the formation has little representation up to Moores- 

 town. Above this place, the valley opens out into a wide flat, 

 30-50 feet in elevation, toward Mount Laurel, and this flat has 

 a thin surface veneer of material which is probably to be 

 correlated with the Cape May formation. In the vicinity of 

 Wilsons Station there are distinct terraces at 20 to 30 feet, but 

 they are of Cretaceous clays. 



Along South Branch, Cape May terraces are better developed. 

 The most conspicuous is on the north side of the creek, a mile 

 or so west of the Moorestown-Ellisburg pike. The terrace here 

 is 30 to 40 feet above sea level, but the Cape May sand and 

 gravel are not more than 10 feet deep on the average. Good 

 exposures of the formation have been seen half a mile west of 

 Mapleshade in the east bank of the stream, in the point of the 

 headland between Pensauken Creek and a small tributary which
