196 Quaternary Formations of Southern New Jersey. 



In general the Cape May mantle in the valley is thin, and back 

 .from the streams is of clay and loam. It connects with that of 

 Alio ways Creek by way of Alio way Station. 



Alloways Creek. — A mile below Quinton, a section in the flat 

 at 20 feet shows 



2) 3 feet of brown sandy loam. 



1)6 feet stratified white sand, with seams of fine gravel. 

 Base unknown. 



This is fairly typical for the Cape May formation of this region. 

 A mile and a half above Quinton a section in the 25-foot terrace 

 shows 



2) 3 feet brown sandy loam. 



1) 7 feet yellowish sand, coarse and fine, carrying seams of fine 

 gravel, horizontally stratified. 

 Miocene, surface 10 to 15 feet above tide. 



Half a mile west of Alloway, there is a terrace at 30 to 35 

 feet, which shows 20 to 25 feet of gravel and sand, underlain 

 by Miocene clay. At Alloway, the Cape May terrace has an 

 altitude of 40 feet. Above Alloway, the formation has some 

 development up to altitudes of 50 feet, but not along the stream. 

 It is seen to rest on the Miocene at some places. 



Cohansey Creek. — South of Salem Creek, the Cape May for- 

 mation expands to the eastward, and borders the bay much as 

 it borders the river farther north. It is found along Cohansey 

 Creek in a narrowing belt up to Dutch Neck, with an upper limit 

 of about 40 feet. It covers a considerable area on the west side 

 of the creek between Dutch Neck and Bridgeton, rising nearly 

 or quite to 50 feet at the latter place, and to 60 or 70 feet near 

 Cedar Grove. Above Bridgeton, however, its development is 

 slight and in most places not very distinct. 



On the right bank of Cohansey Creek the Cape May forma- 

 tion covers all the lowland south of Fairton, and overspreads a 

 belt several miles wide along the bay farther east. Its land- 

 ward limit, roughly defined by the railway from Fairton to 

 Mauricetown Station, has an elevation of about 40 feet; but
