POSTGLACIAL FAULTS OF EASTERN NEW YORK II 



These faults appear to be limited to the fragile shales or slates 

 lying on the eastern side of the sandstone body above mentioned. 



Fig. 3 Sketch map of the postglacial faults on the hillside south of the Poesten kill in Troy. 

 The parallel oblique lines indicate the direction of the glacial striae across the exposure. The 

 group of heavy black lines shows the position of the faults. Plus and minus signs stand for 

 uplifted and downthrown sides respectively; the area left white is the clay-covered portion of 

 the area mapped. The triangular shaded area is that covered by the photograph in plate 3.
