  terrace 
  near 
  the 
  top 
  of 
  the 
  hill, 
  and 
  can 
  be 
  traced 
  for 
  quite 
  a 
  

   distance. 
  

  

  90 
  feet, 
  covered. 
  

  

  16 
  feet, 
  massive 
  red 
  sandstone. 
  This 
  ledge 
  forms 
  the 
  top 
  of 
  

   the 
  hill 
  at 
  this 
  point, 
  although 
  a 
  little 
  farther 
  toward 
  the 
  south 
  

   the 
  mountain 
  rises 
  some 
  50 
  feet 
  higher. 
  

  

  It 
  will 
  be 
  noticed, 
  by 
  referring 
  to 
  the 
  maps, 
  that 
  the 
  top 
  of 
  this 
  

   section 
  is 
  very 
  near 
  to 
  the 
  line 
  between 
  the 
  Oneonta 
  and 
  the 
  

   Cats-kill. 
  However 
  it 
  seems 
  best 
  to 
  regard 
  the 
  rocks 
  here 
  de- 
  

   scribed 
  as 
  being 
  entirely 
  of 
  the 
  former 
  formation, 
  and 
  to 
  con- 
  

   sider 
  that 
  this 
  ledge 
  of 
  red 
  sandstone 
  is 
  very 
  nearly 
  if 
  not 
  quite" 
  

   the 
  upper 
  member 
  of 
  the 
  Oneonta 
  formation. 
  This 
  Oneonta-Cat- 
  

   skill 
  line 
  can 
  be 
  only 
  an 
  arbitrary 
  one 
  as 
  in 
  this 
  region 
  the 
  rocks 
  

   are 
  so 
  nearly 
  identical 
  in 
  their 
  lithologic 
  characters 
  as 
  to 
  be 
  quite 
  

   indistinguishable. 
  

  

  This 
  same 
  line 
  of 
  hills 
  was 
  crossed 
  at 
  three 
  other 
  places 
  in 
  

   this 
  vicinity, 
  namely, 
  at 
  East 
  Delhi 
  about 
  two 
  miles 
  farther 
  

   toward 
  the 
  northeast, 
  at 
  Delhi 
  village 
  about 
  one 
  fourth 
  of 
  a 
  

   mile 
  south, 
  and 
  at 
  Scotch 
  mountain 
  three 
  miles 
  to 
  the 
  south. 
  

   The 
  sections 
  show 
  such 
  great 
  similarity 
  that 
  it 
  seems 
  unneces- 
  

   sary 
  to 
  describe 
  the 
  other 
  three 
  fully. 
  The 
  rocks 
  are 
  all 
  of 
  

   the 
  typical 
  Oneonta, 
  the 
  shales 
  being 
  red 
  and 
  soft, 
  while 
  the 
  

   coarse 
  grained, 
  gray 
  sandstones 
  in 
  thin 
  layers, 
  and 
  presenting 
  

   the 
  curious 
  crossbedded 
  appearance, 
  belong, 
  very 
  certainly, 
  to 
  

   this 
  formation. 
  

  

  Mr 
  Darton 
  claims 
  a 
  "narrow 
  belt 
  of 
  Chemung, 
  as 
  capping 
  

   the 
  hills 
  on 
  the 
  eastern 
  side 
  of 
  the 
  Delaware 
  river 
  in 
  this 
  region, 
  

   and 
  extending 
  eastward 
  into 
  the 
  adjoining 
  counties. 
  He 
  says 
  

   that 
  the 
  Chemung 
  is 
  " 
  here 
  represented 
  by 
  a 
  heavy 
  mass 
  of 
  

   coarse, 
  gray, 
  crossbedded 
  sandstones 
  with 
  flaggy 
  layers. 
  Its 
  

   thickness 
  averages 
  about 
  250 
  feet." 
  But 
  as 
  there 
  are 
  to 
  be 
  found 
  

   no 
  traces 
  of 
  Chemung 
  fossils 
  in 
  this 
  region; 
  and 
  as 
  it 
  is 
  impos- 
  

   sible 
  to 
  identify 
  any 
  considerable 
  thickness 
  of 
  the 
  gray 
  sand- 
  

   stone 
  which 
  does 
  not 
  show 
  intercalated 
  beds 
  of 
  red 
  sandstone 
  

   and 
  shales, 
  it 
  seems 
  better 
  to 
  consider 
  that 
  the 
  Chemung 
  has 
  

   entirely 
  disappeared, 
  and 
  to 
  regard 
  the 
  Catskill 
  as 
  lying 
  directly 
  

   upon 
  the 
  Oneonta.

  The 
  rocks 
  seen 
  along 
  the 
  Delaware 
  river 
  across 
  Delhi 
  township 
  

   are 
  mostly 
  red 
  shales 
  and 
  sandstones 
  with 
  some 
  gray 
  or 
  greenish 
  

   gray 
  rocks. 
  They 
  apparently 
  belong 
  in 
  the 
  Oneonta 
  formation 
  

   as 
  they 
  are 
  represented 
  on 
  the 
  Geologic 
  map 
  of 
  New 
  York. 
  Col. 
  

   Jewett 
  stated 
  that 
  Mr 
  Way 
  collected 
  Chemung 
  fossils 
  at 
  Delhi"
