  The 
  land 
  areas 
  varied 
  considerably 
  in 
  extent 
  from 
  time 
  to 
  time, 
  

   but 
  the 
  principal 
  area 
  of 
  unsubmerged 
  Precambric 
  rock 
  ran 
  in 
  a 
  

   northeast-southwest 
  direction 
  through 
  the 
  southern 
  Adirondack 
  re- 
  

   gion 
  and 
  most 
  likely 
  continued 
  through 
  the 
  northern 
  region.

  This 
  prominent 
  northeast-southwest 
  structural 
  belt 
  or 
  axis 
  of 
  

   elevation, 
  occupying 
  practically 
  the 
  same 
  position 
  as 
  the 
  present 
  

   main 
  axis 
  of 
  elevation 
  of 
  the 
  mountains, 
  has 
  played 
  an 
  important 
  

   part 
  in 
  the 
  geological 
  history 
  of 
  northern 
  New 
  York.
