[98 Quaternary Formations of Southern New Jersey. 



the valley of Patcong Creek. In the vicinity of Pleasantville, 

 older formation (above 35 to 40 feet) extend out to within 

 less than a mile of the salt marshes, but the formation expands 

 again over a bay-like area in the lower part of Absecon Creek, 

 extending up to Doughty' s and beyond. Just above Absecon 

 it narrows to belt less than a mile wide at Leeds Point, but 

 expands greatly in the valley of Mullica River, above Great Bay. 

 Here it covers a large area of lowland, from Leeds Point to 

 Smithville, Hewittville, Unionville, and Batsto. It extends up 

 Wading River, tributary to the Mullica, several miles above 

 Harrisonville, reaching an elevation of more than 100 feet, and 

 covers most of the area south of a line from Harrisonville to 

 Nugentown. In most of this area it is confined to levels slightly 

 below 40 feet, but near the heads of the valleys it rises a little 

 higher. It is hardly recognizable above elevations of 50 feet. 

 West of Tuckerton there is an area of some older formation 

 (Pensauken?) rising above the Cape May level (40 feet). 



There is some expansion of the formation up the valleys of 

 Shords Mill Brook above Tuckerton, and up Westecunk Creek 

 above West Creek. A mile north of Cox's Station, older forma- 

 tions extended east to the railway, and the Cape May border 

 is narrow to Manahawkin, being restricted virtually to the coastal 

 belt less than 35 feet in elevation. At Manahawkin it again 

 widens, but to the eastward, rather than inland. Cape May 

 deposits here are hardlv separable from younger deposits. 



The formation is wanting some of the way between Mana- 

 hawkin and Barnegat, but from the iatter place to Toms River 

 it forms a belt 1 to 2 miles wide most of the way, and expands 

 up Ewing Valley, holding quite strictly to levels of less than 

 40 feet along the coast, but rising slightly up the valleys. Up 

 Cedar Creek, for example, it reaches an elevation of 60 feet at 

 Dover Forge, and more than 100 feet at Webbs Mill. 



Toms River. — About the mouth of Toms River, the Cape May 

 formation retains its habits of the region farther south, being 

 restricted to the area below 35 feet along the coast, and cover- 

 ing most such areas. 



Island Heights is of older beds, but the Cape May formation 

 extends up Toms River and its principal tributaries, in rather
