HIGH HILL POINT. 



Southeast of High Hill Point, near the western end of the beach, is an 

 exposure of very coarse conglomerate, with pebbles often 15 inches long. 

 An included sandstone layer shows the dip to be about 10° E. At the 

 south end of High Hill Point the coarse conglomerate is again exposed. 

 Near the east there is an included sandstone bed showing horizontal bedding. 

 Farther west, and higher up the cliff, another interbedded sandstone layer 

 shows a dip of 10° W. The same dip is shown at the north end of High 

 Hill, although here the sandstone layer abuts against conglomerate on the 

 east, and is itself cut off by conglomerate on the west, so abruptly as to 

 make the real bedding at first sight uncertain. The conglomerate is 

 exposed in a small indentation north of the hill, and continues along the 

 bank northward for a short distance. Toward the west of the most northern 

 exposure of the coarse conglomerate a fine conglomerate overlain by a little 

 sandstone comes in, having a dip of 30° E., and this is underlain by coarse 

 sandstone, which in certain layers is so full of very small pebbles, an inch 

 and less in size, that the rock may be termed a fine conglomerate. Occa- 

 sionally the rock contains coarser layers, with pebbles up to 1 J or 2 inches 

 in length. 



The great mass of thei^ock, however, is sandstone or the very fine con- 

 glomerate. It continues to be exposed northward for a quarter of a mile, 

 the dip, however, soon diminishing to 10° E. The general strike of the 

 rocks seems to be about N. 10° E. The sandstone is very similar to the 

 sandstone bordering the shore southwest of^ Windmill Hill, southward 

 toward Browns Point, and with this it is correlated. The overlying coarse 

 conglomerate is correlated with the exposure on the west side of Windmill 

 Hill, just west of the farm house. 



FOGLAND POINT. 



A short distance north of the southern end of the headland terminat- 

 ing in Pogland Point, the very coarse conglomerate with l^ge pebbles is 

 exposed, and from that place northward it borders the shore halfway to 

 the point The strike is about N. 10° E., dip 10° E., becoming a little less
