This series of faults cuts through the early Paleozoic strata along 
the shores of Lake Champlain and in the Mohawk valley, and in 
these regions, due to marked differences in the rocks affected, it 
has been possible to determine carefully the character of the faults 
and the amounts of the displacements (see plate 37). Figure 25 
shows two sections through the faulted region of the Mohawk

Fic. 26 Geologic and topographic map of the vicinity of Northville (Ful- 
ton county), showing an unusual variety of rock formations and structures 
along the southern border of the Adirondacks where the Precambric and 
Paleozoic rocks come together, and where all have been greatly faulted. The 
position of the structure section is indicated by the line AB, the vertical 
scale of the section being twice exaggerated. The greatest fault is the one 
on the west, and the country immediately on the east side of it has dropped 
fully 1500 feet with respect to that on the west (mountain) side. Northville 
lies between two smaller faults and on an earth block which has dropped 
several hundred feet with respect to the country on either side.
