142 Quaternary Formations of Southern New Jersey. 



Between the branches of Tepeheptus Brook there are other 

 patches of gravel similarly situated, at elevations ranging from 

 170^+ to no feet, the hig-her elevations being to the east, 2 

 miles or so west of Marlboro. These hills, taken with other 

 patches at similar elevations in the vicinity, seem to point to a 

 widespread accumulation of gravel at a level which is now about 

 180 feet above the sea in the vicinity of Freehold. It is thought 

 that the gravels here referred to accumulated in the valleys at 

 about this level. The sites of the valleys have been changed 

 since, and their former sites have, in some places, become divides. 

 The base of the gravel in some of these patches about the head- 

 waters of Tepeheptus Brook is very irregular, in a small way, 

 and the irregularities are not unlike those developed in the chan- 

 nels of existing streams. 



Between Tepeheptus Brook and Milford Brook and about the 

 headwaters of the latter, the phenomena just described are 

 repeated, the gravels being at similar levels, 170+ feet. The 

 patches show a tendency to elongation on the divides parallel to 

 the streams. The higher tracts (170 to 180 feet) covered with 

 gravel adjoin still higher lands (200dr feet) on the east, east of 

 north of Freehold. These high lands carry some gravels which 

 seem to be older than the remnants at lower levels to the west, 

 though this may be questioned. The high gravels hereabout are 

 cemented to a considerable extent, and so have the appearance 

 of greater age. 



Are the gravels between Englishtown and Freehold the equiv- 

 alent of those northwest of Englishtown? To this question no 

 positive answer can be given. The former have the appearance 

 of having been accumulated in stream valleys, for they vary from 

 valley to valley, in keeping with the terranes affected by the 

 drainage system. West of Englishtown, such a relation is not 

 evident. 



If these gravels east of Englishtown were once part of the 

 main body of Pensauken to the west, they would seem to call for 

 the building up of the area between Englishtown and Freehold 

 to i8o± feet by Pensauken deposits. In this case the remnants 

 we now find at 120 feet are basal remnants of a bed once 60 to
