The Dolgeville fault exposed in the bank of East Canada creek. At the 

 right the fault is at the base of the vertical cliff, which consists entirely of 

 Beekmantown layers, the Lowville capping not showing in the view. Over 

 most of the cliff the fault breccia is still in place, so that the stratification 

 shows only here and there. The fault plane is seen to diagonally ascend 

 the cliff face from right to left, commencing at the dark bush and following 

 the line of bushes. The sloping surfaces below are those of the updragged 

 layers of Utica shale, whose stratification may be made out at the extreme 

 left.
