1 68 Quaternary Formations of Southern New Jersey. 



Pond Run.- — The Cape May formation has no distinct develop- 

 ment in the basin of this creek, above the Trenton plain; but thin 

 deposits perhaps to be correlated with it are found over the 

 lowland nearly to the sources of the stream. They do not con- 

 stitute distinct terraces, but line the lower parts of the basin up 

 to the Pensauken level. The most that can be said of the surface 

 deposit over this lowland is that it is post- Pensauken, and a large 

 part of it is no doubt Cape May. 



Miry Run. — : Cape May gravels and sands exist along this 

 valley up to Newtown, but the volume of the formation is slight. 

 Its materials are from the Cretaceous and Pensauken formations, 

 the only formations accessible to* the stream and its tributaries. 

 The material is but a few feet above the stream 1 , much of it in 

 low terraces 5 to 15 feet above the bottom of the valley. In con- 

 stitution it is different enough from the Pensauken (or Cre- 

 taceous) above, so that the limits of the deposits are fairly well 

 defined in the soil. 



On the uplands, especially north of Miry Run, there is some 

 loam (and sand) which appears to be wind blown, and to contain 

 material derived from the Trenton (glacial) gravels and sands. 

 The same sorts of loam and sand are seen interruptedly from 

 Miry Run to White Horse. 



Assanpink Valley. — Up to Bakers Basin and Lawrence Station 

 this creek flows through the low plain (60 feet) covered by 

 glacial gravel ; but above Lawrence Station its valley is compara- 

 ble to the valleys of other creeks of the region. The stream is 

 a long one, heading back in the Clarksburg hills ; but above 

 Lawrence Station, its valley is relatively narrow. 



The Cape May deposits of this valley are nearly continuous, 

 on the north bank of the stream, up to New Sharon, but have 

 little development on the south side, though there is a well-defined 

 terrace at Edinburgh, at an elevation of 80 to 90 feet, on the left 

 bank. In the vicinity of Lawrence Station, the material is mostly 

 sand; but farther up there is more gravel. Above Edinburgh, 

 much of the material is in terraces, 10 to 25 feet above the 

 stream. The terraces are for the most part ill defined, and their 

 constitution varies much from point to point in the valle)^. In
