  The 
  outlet 
  to 
  the 
  Naples 
  lake 
  was 
  over 
  the 
  col 
  into 
  the 
  

   Cohocton 
  creek 
  valley. 
  (Fignre

  The 
  elevation 
  has 
  not 
  

   been 
  taken. 
  The 
  terraces 
  marking 
  this 
  stage 
  are 
  large 
  and 
  

   well 
  developed, 
  though 
  some 
  of 
  the 
  highest 
  have 
  suffered 
  

   slight 
  erosion, 
  causing 
  a 
  somewhat 
  irregular 
  surface. 
  The 
  

   waters 
  fell 
  very 
  gradually 
  from 
  the 
  l^aples 
  level 
  to 
  that 
  of 
  lake 
  

   Newberry, 
  which 
  condition 
  is 
  well 
  shown 
  in 
  a 
  series 
  of 
  some 
  

   four 
  or 
  more 
  quite 
  strongly 
  deiined 
  terraces, 
  occurring 
  at 
  eleva- 
  

   tions 
  intermediate 
  between 
  the 
  Naples 
  and 
  Newberry 
  stages.

  Evidence 
  and 
  history 
  of 
  lake. 
  The 
  final 
  outlet 
  to 
  glacial 
  

   lake 
  Groton 
  was 
  over 
  the 
  col, 
  in 
  the 
  region 
  of 
  North 
  Lansing 
  

   with 
  an 
  elevation 
  of 
  970+ 
  feet. 
  The 
  southern 
  end 
  of 
  the 
  Owasco 
  

   valley 
  is 
  clogged 
  with 
  moraine, 
  which 
  begins 
  at 
  Locke 
  and 
  extends 
  

   southward 
  to 
  and 
  beyond 
  Groton, 
  thus 
  giving 
  a 
  width 
  uf 
  some 
  four 
  

   miles. 
  The 
  moraine 
  is 
  fairly 
  well 
  developed 
  in 
  some 
  places 
  and 
  rather 
  

   scanty 
  in 
  others. 
  It 
  is 
  partly 
  stratified 
  in 
  places, 
  but 
  for 
  the 
  most 
  

   part 
  it 
  is 
  made 
  up 
  of 
  the 
  unassorted 
  material 
  so 
  characteristic 
  of 
  true 
  

   moraines. 
  The 
  divide, 
  however, 
  is 
  located 
  some 
  eight 
  miles 
  south 
  

   of 
  the 
  moraine 
  at 
  Dryden 
  summit 
  with 
  an 
  elevation 
  of 
  1220.9 
  feet 
  

   above 
  tide. 
  The 
  valley 
  is 
  a 
  broad 
  one, 
  and 
  the 
  walls 
  or 
  sides 
  are
