  HAMILTON 
  AND 
  CHEMUNG 
  SERIES

  W. 
  Above 
  the 
  red 
  rocks 
  are 
  massive 
  greenish 
  gray 
  or 
  grayish 
  

   sandstones 
  and 
  green 
  argillaceous 
  shales. 
  Succeeding 
  these 
  

   rocks 
  is 
  a 
  prominent 
  band 
  of 
  red 
  argillaceous 
  shale 
  containing 
  

   some 
  green 
  shale 
  with 
  a 
  total 
  thickness 
  of 
  between 
  40 
  and 
  50 
  feet. 
  

   On 
  the 
  hill 
  one 
  and 
  one 
  half 
  miles 
  above 
  Wurtsboro 
  the 
  rocks 
  

   are 
  nearly 
  all 
  covered 
  by 
  drift 
  for 
  some 
  distance 
  along 
  the 
  road. 
  

  

  By 
  the 
  side 
  of 
  the 
  valley 
  road 
  over 
  one 
  half 
  a 
  mile 
  southwest 
  

   of 
  Wurtsboro 
  are 
  fine, 
  blue 
  Hamilton 
  shales, 
  which 
  contain 
  some 
  

   fossils, 
  though 
  they 
  are 
  not 
  abundant. 
  Perhaps 
  one 
  and 
  one 
  half 
  

   miles 
  below 
  Wurtsboro 
  is 
  a 
  good 
  outcrop 
  of 
  these 
  bluish, 
  fine 
  

   Hamilton 
  shales, 
  which 
  contain 
  but 
  few 
  fossils. 
  The 
  dip 
  at 
  this 
  

   locality 
  is 
  75° 
  N, 
  50° 
  W. 
  In 
  general 
  this 
  is 
  the 
  case 
  with 
  these 
  

   somewhat 
  blocky 
  shales 
  of 
  the 
  lower 
  Hamilton 
  as 
  exposed 
  along 
  

   the 
  valley 
  road 
  to 
  the 
  west 
  of 
  the 
  Basherskill. 
  

  

  The 
  rocks 
  along 
  the 
  Pinekill 
  in 
  the 
  southern 
  part 
  of 
  Mamakat- 
  

   ing 
  township 
  for 
  at 
  least 
  two 
  miles 
  above 
  West 
  Brookville 
  are 
  

   all 
  covered 
  by 
  drift. 
  The 
  country 
  is 
  rough 
  and 
  there 
  are 
  large 
  

   numbers 
  of 
  glacial 
  boulders 
  of 
  various 
  sizes. 
  

  

  On 
  the 
  hill 
  just 
  northwest 
  of 
  Cuddebackville 
  are 
  black 
  argil- 
  

   laceous 
  shales 
  in 
  the 
  upper 
  part 
  of 
  the 
  Hamilton 
  formation, 
  con- 
  

   taining 
  abundant 
  fossils.
