The faiilteii Pale()/oi<' reiirion of New York State has hitherto been regarded 

 as ooiitiiied to the Mohawk Valley * and the areas north - and east.' No con- 

 siderable fault has been recorded west of Little Falls,* except one in the 

 vicinity of Trenton Falls.' An unrecorded (or the same?) fault probably 

 exists along the line of Stebbins Creek,*'' northeast of Clinton, New York.

which, like the Trenton fault, differs frcrtn the rule of the Mohawk Valley 

 displacements by having its downthrow on the west side. 



A similar downthrow on the west characterizes the fault to be described, 

 l»ut it shows itself o.stensibly as a northward shove of the downthrow side
