  . 
  Only 
  10 
  feet 
  above 
  this 
  terrace 
  of 
  the 
  Ithaca 
  shales 
  

   is 
  a 
  ledge 
  of 
  gray, 
  coarse 
  grained, 
  thin 
  bedded 
  sandstone 
  with 
  the 
  

   lithologic 
  appearance 
  of 
  the 
  Oneonta. 
  20 
  feet 
  above 
  its 
  base 
  red 
  

   sandstone 
  was 
  found 
  which 
  was 
  thought 
  to 
  come 
  from 
  a 
  stratum 
  

   at 
  about 
  that 
  horizon 
  but 
  perhaps 
  this 
  is 
  not 
  the 
  case. 
  There 
  

   is, 
  however, 
  some 
  positive 
  support 
  for 
  the 
  supposition 
  that 
  this 
  

   red 
  sandstone 
  is 
  nearly 
  in 
  place 
  since 
  at 
  Gilboa 
  in 
  the 
  Schoharie 
  

   river 
  are 
  red 
  sandstones 
  and 
  shales 
  which 
  according 
  to 
  Sher- 
  

   wood's 
  section 
  are 
  666 
  feet 
  above 
  the 
  gray 
  sandstone 
  which 
  

   makes 
  the 
  rapids 
  in 
  the 
  river 
  at 
  North 
  Blenheim 
  ; 
  while 
  the 
  red 
  

   sandstone 
  on 
  the 
  hill 
  west 
  of 
  North 
  Blenheim 
  is 
  approximately 
  

   670 
  feet 
  above 
  the 
  same 
  horizon. 
  90 
  feet 
  above 
  the 
  red 
  sand- 
  

   stone 
  is 
  a 
  cliff 
  of 
  massive 
  coarse 
  grained, 
  greenish 
  sandstone, 
  

   forming 
  the 
  eastern 
  end 
  of 
  the 
  hill, 
  at 
  an 
  altitude 
  of 
  760 
  feet 
  

   above 
  the 
  river 
  level. 
  This 
  sandstone 
  in 
  its 
  lithologic 
  appear- 
  

   ance 
  closely 
  resembles 
  the 
  Oneonta 
  although 
  it 
  probably 
  occurs 
  

   <d 
  a 
  lower 
  horizon 
  than 
  the 
  sandstone 
  farther 
  west 
  in 
  Jefferson 
  

   township 
  which 
  has 
  been 
  called 
  the 
  base 
  of 
  the 
  Oneonta 
  forma- 
  

   tion.

  This 
  section 
  follows 
  the 
  highway 
  from 
  North 
  Blen- 
  

   heim 
  toward 
  Jefferson 
  along 
  the 
  side 
  of 
  the 
  steep 
  hill 
  to 
  the 
  

   north 
  of 
  Mill 
  creek 
  and 
  is 
  nearly 
  parallel 
  to 
  the 
  section 
  just 
  de- 
  

   scribed. 
  The 
  exposures 
  for 
  the 
  lower 
  part 
  of 
  it 
  are 
  about 
  the 
  

   same 
  as 
  those 
  for 
  XXVIII 
  D, 
  above 
  which 
  the 
  rocks 
  are 
  covered 
  

   for 
  a 
  considerable 
  thickness, 
  and 
  this 
  part 
  is 
  called 
  H 
  1 
  . 
  At 
  440 
  

   feet 
  above 
  the 
  river 
  a 
  heavy 
  bedded, 
  quite 
  coarse 
  grained, 
  mas- 
  

   sive, 
  greenish 
  gray 
  sandstone 
  is 
  reached 
  (H 
  2 
  ), 
  30 
  feet 
  of 
  which 
  

   is 
  shown 
  in 
  the 
  highway 
  and 
  this 
  is 
  succeeded 
  by 
  35 
  feet 
  of 
  

   greenish 
  and 
  bluish, 
  smooth, 
  argillaceous 
  shales 
  (H 
  3 
  ). 
  No 
  fossils 
  

   were 
  found 
  either 
  in 
  the 
  sandstone 
  or 
  the 
  shales. 
  The 
  eleva- 
  

   tion 
  of 
  this 
  sandstone, 
  440 
  feet 
  above 
  the 
  river, 
  agrees 
  closely 
  

   with 
  the 
  thickness 
  of 
  431 
  feet 
  assigned 
  by 
  Sherwood 
  to 
  the 
  rocks 
  

   from 
  the 
  rapids 
  at 
  North 
  Blenheim 
  (formerly 
  Patchin 
  Hollow) 
  

   to 
  the 
  coarse 
  gray 
  sandstone 
  which 
  forms 
  the 
  top 
  of 
  the 
  Little
