Total thickness :ilO 



Beds 68 and 69, instead of belonging to the base of the 

 section, may be a repetition of some of those above. Several 

 downthrow^s to the northeast then seem to repeat othfers, but are 

 perhaps counterbalanced by faults with downthrow to the 

 southwestward. 



Ninety yards northeastward from the outcrop of 69, after 

 two little downthrows have brought the red shale upon the 

 beach, the gray sandstone (68) is in the cliff to a height of forty 

 feet as before, the reefs striking apparently along the shore. 

 About 2Y5 yards farther east, red rock is capped in the cliff 

 by gray and rusty sandstone, and at 140 yards still farther 

 northeast is brought against greenish and gray sandstone by a 

 fault. These latter are almost certainly the beds 45 to 58 of 

 Section IV. ; an d the succeeding strata are those of Section III.
