  Lake 
  Newberry 
  was 
  tlie 
  most 
  extensive 
  and 
  comprehensive 
  body 
  

   of 
  water 
  in 
  New 
  York 
  state 
  south 
  of 
  the 
  Great 
  Lakes. 
  Its 
  level, 
  

   along 
  the 
  stream 
  courses 
  tributary 
  to 
  the 
  lake 
  valleys 
  with 
  eleva- 
  

   tions 
  above 
  sea 
  level, 
  is 
  indicated 
  in 
  the

  tabular 
  statement 
  of 
  

   the 
  delta 
  terraces 
  marked 
  Newberry 
  stage.

  The 
  Newberry 
  level 
  found 
  on 
  the 
  Taughannock-Trumansburg 
  

   creeks 
  is 
  especially 
  noteworthy 
  on 
  account 
  of 
  its 
  size 
  and 
  development. 
  

   While 
  these 
  streams 
  enter 
  Lake 
  Cayuga 
  at 
  present 
  through 
  distinct 
  

   channels 
  separated 
  from 
  each 
  other 
  by 
  a 
  distance 
  of 
  about 
  two 
  miles, 
  

   careful 
  study"* 
  has 
  revealed 
  the 
  fact 
  that 
  Trumansburg 
  creek 
  was 
  a 
  

   tributary 
  to 
  Taughannock 
  creek 
  in 
  preglacial 
  times, 
  with 
  its 
  point 
  of 
  

   confluence 
  a 
  little 
  south 
  but 
  near 
  the 
  town 
  of 
  Trumansburg. 
  The 
  

   Newberry 
  delta 
  has 
  obscured 
  the 
  place 
  of 
  contact 
  or 
  junction. 
  During 
  

   this, 
  as 
  well 
  as 
  the 
  Ithaca 
  stage, 
  the 
  two 
  streams 
  were 
  dismembered 
  

   and 
  entered 
  glacial 
  lakes 
  Ithaca 
  and 
  Newberry 
  as 
  separate 
  streams. 
  

   Each 
  began 
  a 
  delta 
  at 
  the 
  Newberry 
  level, 
  and 
  these, 
  before 
  

   its 
  close, 
  coalesced 
  into 
  one 
  immense 
  deposit. 
  It 
  covers 
  a 
  large 
  area 
  

   and, 
  so 
  far 
  as 
  revealed 
  by 
  sections, 
  exposed 
  in 
  many 
  places, 
  is 
  almost 
  

   entirely 
  composed 
  of 
  fine 
  material. 
  The 
  sand 
  from 
  this 
  delta 
  has 
  

   an 
  extended 
  local 
  reputation 
  for 
  building 
  purposes 
  in 
  that 
  section. 
  

   Its 
  front 
  is 
  fairly 
  well 
  defined 
  throughout, 
  though 
  more 
  con- 
  

   spicuously 
  developed 
  along 
  the 
  south 
  side 
  of 
  Trumansburg 
  creek 
  

   where 
  the 
  town 
  cemetery 
  is 
  situated. 
  The 
  delta 
  top 
  is 
  quite 
  level, 
  

   but 
  broken 
  here 
  and 
  there 
  by 
  slight 
  irregularities 
  in 
  the 
  form 
  of 
  

   sand 
  accumulations. 
  It 
  rivals 
  any 
  shore 
  deposit 
  found 
  anywhere 
  

   in 
  the 
  Finger-lake 
  region. 
  

  

  When 
  the 
  Newberry 
  waters 
  were 
  at 
  their 
  maximum 
  they 
  meant 
  

   the 
  blending 
  of 
  the 
  waters 
  of 
  the 
  higher 
  levels 
  in 
  all 
  of 
  the 
  local 
  

   lakes, 
  from 
  Lake 
  Canandaigua 
  on 
  the 
  west 
  to 
  Lake 
  Skaneateles 
  on 
  

   the 
  east. 
  This 
  stage 
  was 
  immediately 
  prior 
  to 
  the 
  easternmost 
  

   extension 
  of 
  the 
  Warren 
  waters 
  across 
  the 
  plain 
  to 
  the 
  south 
  of 
  a 
  

   portion 
  of 
  Lake 
  Ontario. 
  The 
  predecessors 
  to 
  this 
  great 
  expanse 
  of 
  

   water, 
  which 
  later 
  fell 
  and 
  united 
  to 
  form 
  the 
  Newberry 
  level, 
  

   caused 
  by 
  a 
  farther 
  removal 
  northward 
  of 
  the 
  waning 
  ice 
  barrier, 
  

   were 
  glacial 
  lakes 
  Skaneateles, 
  Groton, 
  Ithaca, 
  Watkins, 
  Hammonds- 
  

   port, 
  Flint 
  creek 
  and 
  Naples.
