  The 
  moraine 
  in 
  tlie 
  divide 
  region 
  of 
  the 
  Keuka 
  valley 
  is 
  well 
  

   developed, 
  and 
  in 
  the 
  neighborhood 
  of 
  Bath 
  merges 
  into 
  and 
  is 
  

   replaced 
  by 
  tiie 
  gravel 
  flood-plains 
  skirting 
  the 
  overflow 
  channel. 
  

  

  As 
  soon 
  as 
  the 
  receding 
  ice 
  sheet 
  had 
  nncovered 
  the 
  lower 
  lands 
  

   in 
  the 
  region 
  of 
  Penn 
  Yan, 
  or 
  the 
  northern 
  part 
  of 
  the 
  present 
  

   lake, 
  the 
  water 
  fell 
  to 
  the 
  level 
  of 
  glacial 
  lake 
  Newberry, 
  some 
  200 
  

   feet 
  below 
  the 
  local 
  lake 
  levels 
  It 
  will 
  be 
  observed, 
  however, 
  in 
  

   the 
  sobsiding 
  of 
  the 
  waters 
  from 
  the 
  Hammondsport 
  to 
  the 
  New- 
  

   berry 
  level, 
  that 
  it 
  was 
  not 
  entirely 
  sudden, 
  but 
  represented 
  by 
  a 
  

   rather 
  prolonged 
  and 
  intermediate 
  halt 
  at 
  an 
  elevation 
  of 
  about 
  1018 
  

   to 
  1020 
  feet. 
  The 
  same 
  intermediate 
  level, 
  in 
  the 
  form 
  of 
  a 
  ter- 
  

   race, 
  while 
  not 
  given, 
  for 
  Laugh 
  lin's 
  glen 
  is 
  as 
  well 
  defined 
  as 
  the 
  

   one 
  measured 
  on 
  Glen 
  brook. 
  

  

  Flint 
  creek 
  stage 
  

  

  Flint 
  creek 
  heads 
  in 
  the 
  Canandaigua 
  territory 
  not 
  far 
  from 
  the 
  

   town 
  of 
  Naples, 
  between 
  lakes 
  Seneca 
  and 
  Canandaigua, 
  and 
  flows 
  

   in 
  an 
  almost 
  direct 
  northerly 
  course 
  to 
  join 
  the 
  Canandaigua 
  outlet 
  

   stream 
  a 
  little 
  west 
  of 
  north 
  from 
  Geneva. 
  It 
  occupies 
  a 
  very 
  

   extensive 
  valley, 
  which 
  was 
  at 
  one 
  time 
  the 
  scene 
  of 
  a 
  lake 
  similar 
  

   to 
  the 
  ones 
  found 
  in 
  the 
  southern 
  portions 
  of 
  the 
  present 
  lake 
  

   valleys, 
  although 
  no 
  definite 
  terraces 
  " 
  were 
  found 
  in 
  any 
  part 
  of 
  the 
  

   valley. 
  When 
  the 
  ice 
  had 
  retreated 
  as 
  far 
  northward 
  as 
  the 
  

   villagres 
  of 
  Gorham 
  and 
  Stanlev 
  the 
  waters 
  in 
  the 
  Flint 
  creek 
  

   valley 
  found 
  a 
  low 
  pass 
  to 
  the 
  east\vard 
  and 
  fell 
  to 
  the 
  Newberry 
  

   level, 
  which 
  level 
  in 
  the 
  Flint 
  creek 
  valley 
  was 
  sustained 
  through- 
  

   out 
  the 
  existence 
  of 
  lake 
  Newberry. 
  Its 
  waters 
  were 
  added 
  to 
  

   Newberry 
  just 
  before 
  or 
  about 
  the 
  time 
  that 
  the 
  waters 
  of 
  glacial 
  

   lake 
  Naples 
  were 
  united, 
  as 
  Flint 
  creek 
  flnds 
  an 
  outlet 
  at 
  present 
  

   through 
  the 
  lowest 
  part 
  of 
  the 
  divide 
  between 
  the 
  upper 
  portion 
  of 
  

   Lakes 
  Seneca 
  and 
  Canandaigua 
  at 
  Stanley. 
  Unlike 
  the 
  other 
  valley 
  

   members 
  of 
  the 
  Finger-lake 
  system, 
  no 
  lake 
  occupies 
  any 
  part 
  of 
  

   the 
  Flint 
  creek 
  valley 
  at 
  present. 
  

  

  o 
  Since 
  this 
  paper 
  was 
  admitted 
  to 
  press, 
  Professor 
  H. 
  L. 
  Fairchild 
  has 
  published 
  an 
  article 
  

   entitled 
  " 
  Kettles 
  in 
  g:lacial 
  lake 
  deltas," 
  Journ. 
  geol., 
  1898, 
  6, 
  589-596, 
  in 
  which 
  he 
  gives 
  the 
  

   elevations 
  of 
  two 
  terraces 
  found 
  near 
  the 
  village 
  of 
  l\>t 
  er 
  on 
  the 
  West 
  side 
  of 
  Flint 
  creek 
  

   valley 
  as 
  follows: 
  1150 
  feet, 
  1080 
  feet. 
  The 
  highest 
  one 
  of 
  these. 
  Fairchild 
  says, 
  "corresponds 
  

   with 
  the 
  summit 
  levels 
  of 
  the 
  several 
  old 
  deltas 
  in 
  the 
  Keuka 
  valley 
  proper," 
  while 
  no 
  positive 
  

   correlation 
  has 
  been 
  worked 
  out 
  from 
  the 
  1080 
  foot 
  level.
