Geologically, the evidence of the scarp being due to a fault may 

 be best indicated by reference to three critical sections. Since these 

 are drawn to scale, as in the case of those illustrating the Rowsley 

 Fault, they also present important physiographic corroboration. 



Immediately north of Greendale, where Dale's Creek emerges 

 from its gorge in the higher Ordovician block, there is an excel- 

 lent geological section indicated in the creek bed. This is shown?
