   The 
  Loon 
  Lake 
  mountain 
  fault-block, 
  as 
  viewed 
  from 
  a 
  point 
  three- 
  

   fourths 
  of 
  a 
  mile 
  to 
  the 
  south-southwest. 
  On 
  the 
  left 
  (west) 
  side 
  the 
  steep 
  

   slope 
  is 
  that 
  scarp 
  of 
  the 
  larger 
  of 
  the 
  two 
  Schroon 
  lake 
  faults. 
  The 
  

   down-tilt 
  of 
  the 
  block 
  toward 
  the 
  east 
  is 
  perfectly 
  shown. 
  The 
  cliff, 
  

   several 
  hundred 
  feet 
  high, 
  which 
  faces 
  the 
  south, 
  is 
  the 
  scarp 
  of 
  the 
  fault 
  

   along 
  the 
  south 
  side 
  of 
  the 
  mountain. 
  The 
  upper 
  portion 
  of 
  this 
  mountain, 
  

   which 
  rises 
  600 
  feet 
  above 
  the 
  valley, 
  consists 
  of 
  Grenville 
  quartzite 
  and 
  its 
  

   lower 
  portion 
  of 
  biotite-garnet 
  gneiss.
