  Evidence 
  and 
  history 
  of 
  lake. 
  The 
  outlet 
  to 
  glacial 
  lake 
  Ithaca 
  

   was 
  over 
  the 
  col 
  at 
  White 
  Church 
  with 
  an 
  elevation 
  of 
  975 
  feet. 
  

   The 
  Ithaca 
  level 
  is 
  defined 
  by 
  a 
  large 
  number 
  of 
  strong 
  and 
  definitely 
  

   developed 
  terraces, 
  varying 
  in 
  elevation 
  from 
  975 
  to 
  1017 
  feet. 
  The 
  

   largest 
  of 
  these 
  are 
  the 
  Brookton 
  delta, 
  formed 
  by 
  the 
  north 
  branch 
  

   of 
  Six 
  Mile 
  creek 
  at 
  the 
  town 
  of 
  Brookton, 
  those 
  on 
  Lick 
  brook 
  and 
  

   Buttermilk 
  on 
  the 
  east 
  side 
  of 
  the 
  Inlet 
  valley, 
  and 
  on 
  West 
  branch 
  

   and 
  Coy 
  glen 
  on 
  the 
  west 
  side. 
  The 
  same 
  level 
  is 
  recorded 
  on
