  Woodlawn 
  Park 
  fault. 
  The 
  first 
  of 
  the 
  two 
  branches 
  given 
  off 
  

   from 
  the 
  main 
  fault 
  at 
  St 
  Clements 
  may 
  be 
  named 
  from 
  this 
  park, 
  

   as 
  it 
  runs 
  through 
  its 
  northern 
  portion. 
  The 
  only 
  rock 
  outcrop 
  in 
  

   this 
  portion 
  of 
  the 
  fault 
  block 
  is 
  the 
  Hoyt 
  limestone 
  exposure 
  at 
  the 
  

   railroad 
  quarry, 
  closely 
  adjacent 
  to 
  Precambric 
  on 
  the 
  north 
  and 
  

   to 
  Little 
  Falls 
  dolomite 
  on 
  the 
  west 
  and 
  south. 
  Farther 
  south 
  

   abundant 
  exposures 
  of 
  Little 
  Falls 
  dolomite 
  and 
  overlying 
  Amster- 
  

   dam 
  limestone 
  occur 
  within 
  the 
  fault 
  block, 
  while 
  across 
  the 
  fault 
  

   to 
  the 
  southeast 
  is 
  drift-covered 
  territory 
  with 
  Canajoharie 
  shale 
  

   for 
  the 
  surface 
  rock. 
  Then 
  the 
  fault 
  runs 
  into 
  shales 
  and 
  is 
  lost, 
  

   as 
  happens 
  to 
  all 
  the 
  faults 
  of 
  the 
  region 
  in 
  like 
  circumstance. 
  The 
  

   throw 
  of 
  this 
  fault 
  north 
  of 
  Saratoga 
  is 
  just 
  about 
  the 
  thickness 
  

   of 
  the 
  Little 
  Falls 
  dolomite 
  in 
  amount, 
  hence 
  300 
  feet 
  at 
  least. 
  

  

  Saratoga 
  fault. 
  The 
  second 
  branch 
  given 
  off 
  from 
  the 
  main 
  fault 
  

  

  at 
  St 
  Clements 
  follows 
  the 
  strike 
  of 
  the 
  main 
  fault 
  into 
  Saratoga 
  

  

  and 
  the 
  upthrow 
  side 
  is 
  constituted 
  

  

  of 
  the 
  platform 
  of 
  Little

  dolomite 
  on 
  which 
  the 
  western 
  half 
  H~ 
  

  

  of 
  the

  is 
  built.

  swerves 
  somewhat

  Broadway, 
  where

  the 
  west.

  The 
  fault 
  has 
  long 
  been 
  known 
  because 
  of 
  its 
  close 
  association 
  with 
  

  

  the 
  older 
  springs 
  at 
  Saratoga, 
  but 
  when 
  compared 
  with 
  the 
  other 
  

  

  breaks 
  of 
  the 
  region 
  its 
  notoriety 
  is 
  found 
  to 
  be 
  out 
  of 
  all 
  proportion 
  

  

  to 
  its 
  magnitude. 
  It 
  is 
  but 
  a 
  small 
  break. 
  In 
  its 
  course 
  through 
  the 
  

  

  village 
  there 
  is 
  everywhere 
  associated 
  with 
  it 
  a 
  narrow 
  wedge 
  of 
  

  

  Amsterdam 
  limestone 
  caught 
  in 
  along 
  the 
  fault 
  zone. 
  This 
  is 
  best 
  

  

  seen 
  back 
  of 
  the 
  Star

  and 
  thence 
  northward
