  The 
  rocks 
  along 
  the 
  lower 
  part 
  of 
  Durham 
  creek 
  are 
  mostly 
  

   covered; 
  but 
  about 
  80 
  feet 
  higher 
  than 
  the 
  Catskill 
  creek 
  level 
  

   is 
  an 
  outcrop 
  of 
  red 
  argillaceous 
  shale 
  (B 
  2 
  ) 
  in 
  its 
  bed. 
  This 
  

   locality 
  is 
  below 
  Durham 
  just 
  beyond 
  the 
  house 
  of 
  Noah 
  Scutt, 
  

   where 
  there 
  is 
  perhaps 
  in 
  all 
  a 
  10 
  foot 
  ledge 
  with 
  three 
  feet 
  of 
  

   red 
  shale 
  at 
  the 
  base. 
  This 
  ledge 
  is 
  in 
  the 
  red 
  rocks 
  of 
  the 
  

   Oneonta 
  formation 
  near, 
  if 
  not 
  quite 
  at, 
  its 
  base, 
  and 
  is 
  appar- 
  

   ently 
  at 
  the 
  same 
  locality 
  at 
  which 
  the 
  base 
  of 
  the 
  Oneonta 
  form- 
  

   ation 
  is 
  represented 
  as 
  crossing 
  this 
  creek 
  on 
  the 
  Geologic 
  map 
  of 
  

   New 
  York. 
  A 
  little 
  higher 
  below 
  and 
  under 
  the 
  viaduct 
  just 
  east 
  

   of 
  Durham 
  village 
  are 
  23 
  feet 
  of 
  bluish 
  sandstone 
  with 
  some 
  

   greenish 
  argillaceous 
  shale 
  partings. 
  No 
  fossils 
  were 
  found 
  in 
  

   these 
  rocks. 
  The 
  dip 
  varies 
  considerably 
  in 
  amount 
  even 
  in 
  a 
  

   short 
  distance, 
  as 
  for 
  example 
  at 
  the 
  base 
  of 
  this 
  outcrop 
  it 
  is 
  

   about 
  ^° 
  to 
  the 
  S>W 
  and 
  2° 
  S, 
  while 
  above 
  the 
  viaduct 
  it 
  is 
  

   5J° 
  S. 
  It 
  is 
  rather 
  difficult 
  however 
  to 
  determine 
  the 
  amount 
  of 
  

   the 
  dip 
  accurately 
  on 
  account 
  of 
  some 
  irregular 
  bedding 
  in 
  the 
  

   rocks. 
  On 
  the 
  highway 
  about 
  one 
  mile 
  west 
  of 
  Durham 
  are 
  

   coarse 
  grained, 
  irregularly 
  bedded, 
  grayish 
  to 
  greenish 
  gray 
  sand- 
  

   stone 
  in 
  thin 
  layers, 
  30 
  feet 
  or 
  more 
  of 
  which 
  are 
  exposed. 
  In 
  

   the 
  upper 
  part 
  of 
  this 
  outcrop 
  some 
  550 
  feet 
  higher 
  than 
  Catskill 
  

   creek 
  is 
  a 
  thin 
  layer 
  of 
  bluish 
  sandstone 
  (B 
  3 
  ) 
  containing 
  fossils. 
  

   The

   Above

  layer 
  is 
  a 
  thin 
  stratum 
  of 
  conglomerate 
  

  

  possibly 
  one 
  foot 
  in 
  thickness. 
  This 
  outcrop 
  is

  village, 
  

   opposite
