206 Quaternary Formations of Southern New Jersey. 



4) 5 feet eolian sand. 



3) 8 feet gravel and sand, well stratified; ironstone conspicuous. 



2) 1 foot glauconitic sand, with laminae of clay. 



1)3 feet fine gravel and sand. 



Up the creek which heads near Wickatunk, there is some 

 Cape May material rising) to nearly 170 feet at Wickatunk. At 

 the lower end of the brook, the material runs up the slope to 

 about 80 feet. For i l / 2 miles above the lower end of the brook, 

 there are terraces at 80 to 90 feet, with 10 feet or less of sand 

 and gravel. There is more of the Cape May gravel and sand 

 on the north than on the south side of the valley, depths of 8 

 to 10 feet being seen at various points. The material is glauco- 

 nitic. 



Pine Brook. — Cape Miay gravel and sand are found up Pine 

 Brook to a point 2 miles above Tinton Falls. At the lower end 

 of the brook there is 20 to 30 feet of terrace material, at the 

 40- to 50-foot levels. Up to Tinton Falls and above, the de- 

 posits are mostly on the north side of the stream., where there are 

 meager and indistinct terraces, ranging from 40 feet in elevation 

 to slightly higher levels. Above Tinton Falls there are terraces 

 at 50' feet, but the Cape May material is thin. 



There is a good deal of eolian sand in the valley of Pine 

 Brook, as on the area between Pine Brook and Hockhockson 

 Brook. 



Just west of Macedonia, in the vicinity of Pine Brook Station, 

 there is an area from 70 to 85 feet in altitude, covered with 6 

 to 10 feet of glauconitic sand, largely eolian. Its source is 

 probably the "Yellow" sand of the Cretaceous, a local phase of 

 the Vincentown formation. Other areas of similar glauconitic 

 sand are known in the vicinity, as between Colts Neck and Tin- 

 ton Falls. The 90-foot areas east and west of Scobeyville, for 

 example, are mantled with it. A bit of gravel occurs at the 

 base of the sand in many places.
