58 Quaternary Formations of Southern New Jersey. 



little. The upper part of the later deposit may be as high as 

 the lower part of the earlier. 



Apparently the Woodmansie area has suffered almost the 

 minimum of erosion since Beacon Hill time. More than any 

 other tract in southern New Jersey, it seems to have been avoided 

 by large streams, since that epoch. There seems therefore to 

 be no adequate reason for excluding these gravels from either 

 formation. 



In Bridgeton time, the Woodmansie upland probably extended 

 farther northwest than now, toward Mt. Misery; but when 

 Rancocas and Crosswicks creeks got their heads into this region, 

 they degraded their basins faster than the Mullica River and 

 Toms River degraded theirs. 



CLARKSBURG TO ISLAND HEIGHTS. 



Location of section. — The section shown in Fig. 34 1 represents 

 the general topographic relations along the divide between Toms 

 River and Metedeconk River, the headwaters of which are 

 close together in the vicinity of Charleston Springs. Metede- 

 conk River was once a larger stream than now, for some of its 

 headwaters have been captured by Manalapan Brook and Mill- 

 stone River. Its earlier source was probably in the Perrineville 

 hills. 



The section is somewhat composite and diagrammatic. It 

 passes through the 354-foot hill a mile north of Clarksburg, 

 and thence southeast nearly to Cassville. Here the 257-foot 

 hill and others at about 190 feet, a little out of line, are brought 

 into the section. Near Cassville the section is offset to the 

 northeast about 2 miles, and is then continued southeastward, 

 parallel to the Metedeconk River to Seven Stars, near Lakewood. 

 From Seven Stars, it follows a line roughly parallel with Toms 

 River,- to Island Heights and thence to Berkeley. Some minor 

 details are omitted. 



To the northwest, the section is carried to Disbrows Hill, 

 Hightstown, Dutch Neck, and Princeton, and the Rocky Hill
