   Crane 
  mountain 
  as 
  viewed 
  from 
  Thurman 
  village. 
  This 
  great 
  dome 
  of 
  

   quartz-syenite 
  rises 
  2000 
  feet 
  above 
  the 
  valley 
  at 
  its 
  base. 
  The 
  valley 
  is 
  

   underlain 
  with 
  Grenville, 
  chiefly 
  limestone. 
  The 
  steep 
  slope 
  on 
  the 
  left 
  

   (south) 
  side 
  is 
  due 
  to 
  a 
  fault 
  scarp, 
  and 
  the 
  down 
  tilt 
  of 
  the 
  great 
  moun- 
  

   tain 
  block 
  toward 
  the 
  right 
  (north) 
  is 
  plainly 
  shown. 
  The 
  escarpment 
  at 
  

   the 
  summit 
  is 
  due 
  to 
  the 
  passage 
  of 
  a 
  minor 
  fault.
