  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 
  2S 
  

   shows 
  two 
  sections 
  through 
  the 
  faulted 
  region 
  of

  Fig.

  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.
