EARLY DENONIC HISTORY OF NEW YORK AND EASTERN NORTH AMERICA 



75 



beds of Cape Barre for a thickness of loo or more feet were squeezed out, 

 and their remnant overturned to their present place and attitude, one fourth 

 mile a\va\', and their dip reversed. 



A displacement of somewhat similar proportions seems to separate the 

 coast cliffs from the thinned edge of the Bonaventure conglomerates and its 

 course is indicated by the swale running from behind Cape Canon to the 

 North beach. The course of this fault is nearly north-south. On the 

 Murailles we find the clearly defined line of displacement along which the 

 Perce beds have slipped down over the Barre beds inverting their dip and 

 this entire mass of Barre and Perce beds was evidently cut off from the 

 Perce rock by the line of faulting just mentioned. 



We find evidence of a minor fault near the middle of the sea cliff of 

 Mt Joli and it seems probable that the massives of Joli and Canon are 

 separated by similar faults which ha\e helped to give origin to the beach 

 between them. These lesser faults probably do not extend very far inland. 

 An interesting local displacement in the Cape Blanc limestones is seen on 

 the highway at the crossing of Hayes creek, just beneath the north face of 

 the hill. Here the creek has made its way through limestone strata which 

 are nearly horizontal, while 50 feet away they are seen to be normally 

 inclined almost to the vertical and overlain by the Bonaventure conglomerate. 



The relations of the limestones and shales here discussed to the over- 

 lying Bonaventure conglomerates will be referred to in a subsequent chapter.
