  numerous 
  other 
  streams 
  entering 
  from 
  each 
  side 
  of 
  the 
  valley, 
  which 
  

   have 
  not 
  reached 
  so 
  marked 
  a 
  degree 
  in 
  development. 
  These 
  can 
  

   be 
  seen 
  by 
  referring 
  to 
  the 
  table 
  of 
  terraces 
  opposite 
  page 
  r84. 
  The 
  

   farthest 
  north 
  that 
  this 
  stage 
  is 
  delineated 
  is 
  just 
  above 
  the 
  town 
  of 
  

   Trumansburg, 
  some 
  11 
  miles 
  north 
  of 
  Ithaca 
  on 
  the 
  west 
  side 
  of 
  

   Lake 
  Cayuga, 
  where 
  the 
  marking 
  is 
  in 
  the 
  form 
  of 
  a 
  very 
  imper- 
  

   fectly 
  defined 
  delta. 
  The 
  line 
  is 
  marked 
  by 
  a 
  small 
  burying 
  

   ground 
  some 
  -iO 
  to 
  50 
  rods 
  away 
  from 
  and 
  on 
  the 
  south 
  side 
  

   of 
  the 
  creek. 
  The 
  ice 
  receded 
  some 
  14 
  miles 
  north 
  of 
  this 
  point 
  

   before 
  the 
  Ithaca 
  stage 
  w^as 
  closed 
  and 
  the 
  next 
  lower 
  inaugurated. 
  

  

  On 
  the 
  east 
  side 
  of 
  the 
  valley 
  the 
  most 
  northerly 
  trace 
  of 
  the 
  

   Ithaca, 
  level 
  is 
  found 
  on 
  Buttermilk 
  creek 
  about 
  two 
  miles 
  south 
  of 
  

   Ithaca, 
  where 
  a 
  very 
  extensive 
  delta 
  has 
  been 
  built 
  with 
  its 
  front 
  

   over-looking 
  the 
  Ithaca 
  wagon 
  road 
  near 
  the 
  stream 
  crossing. 
  This 
  

   may 
  be 
  due 
  to 
  the 
  failure 
  to 
  recognize 
  these 
  shore 
  lines 
  among 
  the 
  

   complex 
  moraine 
  of 
  Fall 
  creek 
  valley. 
  

  

  When 
  the 
  ice 
  had 
  withdrawn 
  from 
  the 
  Inlet 
  and 
  Six 
  Mile 
  creek 
  

   valleys, 
  sufficiently 
  for 
  the 
  West 
  Danby 
  waters 
  to 
  fall 
  to 
  the 
  White 
  

   church 
  level, 
  the 
  West 
  Danby 
  and 
  White 
  Church 
  glacial 
  lakes 
  

   coalesced 
  to 
  mark 
  the 
  beo:innino^ 
  of 
  a 
  lower 
  and 
  more 
  extended 
  

   body, 
  that 
  of 
  glacial 
  lake 
  Ithaca, 
  This 
  level 
  in 
  the 
  static 
  waters 
  

   was 
  held 
  until 
  the 
  ice 
  had 
  wasted 
  back 
  sufficiently 
  to 
  uncover 
  the 
  

   low 
  divide 
  between 
  lakes 
  Cayuga 
  and 
  Seneca 
  in 
  the 
  neighborhood 
  

   of 
  the 
  town 
  of 
  Ovnd, 
  with 
  the 
  overflow 
  established 
  at 
  White 
  Church, 
  

   when 
  the 
  waters 
  fell 
  to 
  the 
  next 
  lower 
  stage, 
  and 
  the 
  outlet 
  shifted 
  

   from 
  the 
  Six 
  Mile 
  creek 
  valley 
  to 
  the 
  col 
  at 
  Horseheads 
  in 
  the 
  

   Watkins 
  valley. 
  

  

  The 
  Ithaca 
  glacial 
  lake 
  represents 
  a 
  period 
  of 
  time 
  much 
  longer 
  

   than 
  that 
  recorded 
  by 
  any 
  one 
  of 
  the 
  previous 
  stages, 
  revealed 
  in 
  

   the 
  number 
  of 
  unusually 
  strong 
  and 
  sharp 
  terraces. 
  The 
  Brookton 
  

   delta 
  already 
  referred 
  to 
  as 
  being 
  one 
  of 
  the 
  most 
  extensive 
  shore 
  

   deposits 
  found 
  in 
  the 
  lake 
  region, 
  was 
  built 
  mostly 
  during 
  the 
  

   Ithaca 
  stage, 
  although 
  its 
  beginning 
  dates 
  back 
  to 
  the 
  life 
  of 
  the 
  

   local 
  glacial 
  lake 
  Brookton.
