  On 
  the 
  hill 
  to 
  the 
  northeast 
  of 
  Bristol 
  church 
  the 
  rocks 
  are 
  all 
  

   coarse 
  sandstones 
  alternating 
  with 
  shales, 
  and 
  belong 
  apparently 
  

   in 
  the 
  Sherburne 
  formation. 
  It 
  seems 
  that 
  the 
  quarries 
  in 
  the 
  

   immediate 
  vicinity 
  of 
  West 
  Hurley 
  are 
  in 
  the 
  Sherburne 
  forma- 
  

   tion, 
  while 
  the 
  older 
  ones 
  near 
  Bristol 
  church 
  and 
  toward 
  Stony 
  

   Hollow 
  are 
  in 
  the 
  Hamilton. 
  Mr 
  Darton 
  called 
  these 
  sandstones 
  

   the 
  " 
  Lower 
  flag 
  series 
  " 
  in 
  his 
  Preliminary 
  report 
  on 
  the 
  geology 
  

   of 
  Ulster 
  county, 
  and 
  stated 
  that 
  "the 
  age 
  of 
  the 
  series 
  is 
  not 
  

   definitely 
  known, 
  but 
  it 
  is 
  in 
  the 
  main 
  of 
  the 
  upper 
  Hamilton 
  

   group; 
  the 
  shales 
  and 
  some 
  of 
  the 
  sandstone 
  beds 
  contain 
  fossils, 
  

   but 
  these 
  have 
  not 
  yet 
  been 
  studied."

  On 
  the 
  Geologic 
  map 
  of 
  New 
  York 
  the 
  base 
  of 
  the 
  Catskill 
  is 
  

   represented 
  as 
  north 
  of 
  the 
  railroad 
  and 
  Olive 
  branch 
  to 
  the 
  west 
  

   of 
  West 
  Hurley. 
  Red 
  shales 
  and 
  sandstone 
  however 
  occur 
  on 
  the 
  

   highway 
  south 
  of 
  the 
  railroad 
  not 
  far 
  west 
  of 
  West 
  Hurley 
  and 
  

   there 
  are 
  a 
  number 
  of 
  excellent 
  exposures 
  of 
  the 
  red 
  rocks 
  on 
  

   the 
  highway 
  between 
  this 
  point 
  and 
  the 
  stone 
  church 
  about 
  four 
  

   .and 
  one 
  half 
  miles 
  west 
  of 
  West 
  Hurley. 
  On 
  the 
  north 
  side 
  of 
  

   the 
  highway 
  about 
  two 
  and 
  one 
  half 
  miles 
  from 
  West 
  Hurley 
  is 
  

   a 
  prominent 
  ledge 
  of 
  crossbedded, 
  gray 
  sandstone 
  which 
  rests 
  

   on 
  red 
  shale. 
  There 
  is 
  also 
  a 
  ledge 
  of 
  red 
  shale 
  on 
  the 
  first 
  north 
  

   and 
  south 
  cross 
  road 
  to 
  the 
  west 
  of 
  West 
  Hurley. 
  The 
  red 
  shale 
  

   *it 
  the 
  base 
  of 
  the 
  Catskill 
  formation 
  evidently 
  crosses 
  the 
  rail-
