  waters 
  on 
  the 
  east, 
  which 
  then 
  occupied 
  the 
  greater 
  part 
  of 
  the 
  

   Laurentian 
  lake 
  basin, 
  and 
  drained 
  southward 
  past 
  Chicago 
  into 
  the 
  

   Mississippi. 
  

  

  Workers 
  in 
  the 
  Lake 
  Ontario 
  region 
  generally 
  agree 
  that 
  the 
  

   withdrawal 
  of 
  the 
  Ontario 
  ice-lobe 
  was 
  northeastward. 
  Accepting 
  

   this 
  as 
  the 
  true 
  condition 
  it 
  necessarily 
  follows 
  that 
  the 
  Mohawk 
  

   valley 
  was 
  still 
  blocked 
  by 
  ice, 
  which 
  in 
  fact 
  has 
  been 
  proven 
  by 
  

   recent 
  work. 
  No 
  drainage 
  could, 
  therefore, 
  i)e 
  effected 
  to 
  the 
  east- 
  

   ward, 
  unless 
  it 
  was 
  subglacial. 
  Furthermore, 
  if 
  the 
  Ontario 
  lobe 
  

   retreated 
  in 
  a 
  northeasterly 
  direction, 
  there 
  was 
  an 
  abundance 
  of 
  

   land 
  to 
  the 
  west 
  uncovered 
  by 
  the 
  ice, 
  and 
  sufHciently 
  low 
  in 
  eleva- 
  

   vation 
  to 
  admit 
  of 
  free 
  passage 
  between 
  the 
  declining 
  stage 
  of 
  New- 
  

   berry 
  and 
  the 
  beghming 
  of 
  the 
  Warren 
  waters. 
  At 
  this 
  stage 
  it 
  is 
  

   unnecessary, 
  therefore, 
  to 
  consider 
  a 
  subglacial 
  drainage 
  to 
  the 
  

   eastward 
  for 
  these 
  waters. 
  

  

  Fairchild 
  '*, 
  in 
  his 
  description 
  and 
  comparison 
  of 
  the 
  karae 
  areas 
  of 
  

   western 
  New 
  York 
  has 
  shown 
  the 
  effect 
  of 
  the 
  Wan-en 
  waters 
  on 
  

   the 
  deposits 
  hi 
  the 
  form 
  of 
  terraces, 
  and 
  truncated 
  sand 
  hills, 
  espe- 
  

   cially 
  in 
  the 
  Victor-Miller's 
  coiners 
  kame 
  areas. 
  (Figure 
  26) 
  In 
  

   speaking 
  of 
  these 
  areas 
  he 
  sa}S,^ 
  "Two 
  strongly 
  developed 
  water 
  

   levels 
  are 
  conspicuous 
  ; 
  the 
  higher 
  between 
  850 
  and 
  900 
  feet, 
  the 
  

   lower 
  about 
  700 
  feet 
  above 
  tide." 
  

  

  These 
  levels 
  show 
  very 
  close 
  agreement 
  with 
  those 
  traced 
  by 
  the 
  

   writer 
  in 
  the 
  lake 
  valleys 
  of 
  the 
  Finger-lake 
  region 
  and, 
  therefore, 
  

   have 
  been 
  correlated 
  with 
  the 
  Warren 
  waters. 
  (See 
  table 
  above, 
  also 
  

   table 
  opposite 
  p. 
  r84) 
  Each 
  level 
  marked 
  by 
  the 
  Warren 
  waters, 
  

   has 
  apparently 
  been 
  recorded 
  in 
  the 
  Finger-lake 
  valleys. 
  The 
  

   higher 
  or 
  upper 
  Warren 
  stage 
  varies 
  between 
  the 
  limits 
  of 
  800 
  to 
  

   860 
  feet 
  in 
  the 
  Finger-lake 
  region. 
  

  

  In 
  1895, 
  Mr 
  Frank 
  Leverett 
  ^ 
  accurately 
  traced 
  the 
  Warren 
  level 
  in 
  

   western 
  New 
  York 
  state, 
  from 
  Hamburg 
  as 
  far 
  eastward 
  as 
  Crittenden, 
  

   to 
  which 
  he 
  has 
  applied 
  the 
  name 
  Crittenden 
  beach. 
  Professor 
  Fair- 
  

   child 
  ** 
  has 
  taken 
  up 
  the 
  level 
  at 
  Crittenden, 
  where 
  its 
  elevation 
  was 
  

   accurately 
  measured 
  one 
  mile 
  southwest 
  of 
  Crittenden 
  and 
  found 
  

   to 
  be 
  858 
  feet 
  above 
  mean 
  sea 
  level. 
  It 
  was 
  then 
  traced 
  eastward 
  

   past 
  the 
  town 
  of 
  Morganville 
  at 
  a 
  distance 
  of 
  one 
  and 
  a 
  half 
  miles
