Bridgeton Formation- — Local Details. 57 



The drainage of the region in the vicinity of Browns Mills, and 

 possibly as far west as Arneys Mount, may once have gone east 

 by way of Buckingham and Boyds Hotel, to Toms River. 



This range of hills has but little gravel (1 to 5 feet), and 

 that on the higher elevations. It seems to represent the last 

 remnant of a gravel bed which once covered the whole area, and 

 which was deposited on a plain of erosion developed after the 

 Beacon Hill epoch. The region is thought to have suffered a 

 degradation of 50- to 75 feet after this epoch, for the Beacon Hill 

 formation originally extended over the region from Whitings 

 to Head of Woods, at a level which is now about 250 to 275 

 feet above sea level. 



GRAVELS (BEACON HILL?) ABOUT WOODMANSIE. 



In the vicinity of Woodmansie there are many patches of 

 gravel at various high levels. To the northward, at Whitings, 

 they are at elevations of 170 to 200 feet; just east of Wheat- 

 lands, at a maximum altitude o-f 201 feet; east of Woodmansie, 

 in the vicinity of Old Half Way, up to altitudes of 213 feet; 

 south of Old Half Way and southeast of Woodmansie, up to 

 208 feet; 3 miles southwest of Woodmansie, near the railroad, 

 up to 204 feet. There is, therefore, a considerable area within 

 5 miles of Woodmansie where the surface rises to an altitude 

 of 200 feet at many points. These higher lands are usually 

 capped with gravel. Its depth is rarely more than 5 or 6 feet, 

 though in occasional pockets twice this thickness is reached. It 

 would appear that the region was once quite generally but thinly 

 covered with gravel at the level of 200 feet, and that the gravel 

 patches now remaining are but remnants. There are numerous 

 gravel remnants at slightly lower levels, some of which, at least, 

 have been displaced downward since deposition. 



The correlation of these gravels is not clear. They seem a 

 little too low for Beacon Hill and a little too high for Bridgeton. 

 They are farther southeast than Whitings, where the Beacon 

 Hill gravels might be a little lower than to the north and north- 

 west. They may include deposits of both epochs, especially if 

 the erosion between the two epochs of deposition was here but
