  Forty-seventh 
  Report

  the 
  State 
  Museum. 
  

  

  were 
  not 
  seen 
  between 
  High 
  Falls 
  and 
  Accord, 
  but 
  it 
  is 
  probable 
  

   that 
  they 
  underlie 
  a 
  well-marked 
  terrace 
  which 
  extends 
  near 
  the 
  

   turnpike. 
  Between 
  Accord 
  and 
  Pine 
  Bush 
  they 
  are 
  exposed 
  

   at 
  several 
  points 
  in 
  low 
  cliffs 
  by 
  the 
  turnpike. 
  At 
  Port 
  Jackson 
  

   there 
  is 
  a 
  low 
  anticline 
  extending 
  from 
  the 
  western 
  ridge 
  

   of 
  the 
  Shawangunk 
  mountains, 
  and 
  the 
  Pentamerus 
  beds 
  rise 
  

   on 
  its 
  western 
  flank, 
  giving 
  rise 
  to 
  a 
  short 
  ridge 
  of 
  moderate 
  

   prominence 
  with 
  cliffs 
  of 
  limestone 
  fifty 
  to 
  sixty 
  feet 
  high. 
  The 
  

   Tentaculite 
  limestone 
  and 
  cement 
  beds 
  are 
  obscurely 
  exposed 
  at 
  

   the 
  base 
  of 
  the 
  southeastern 
  side 
  of 
  this 
  ridge. 
  The 
  cement 
  is 
  

   said 
  to 
  be 
  of 
  considerable 
  thickness 
  and 
  excellent 
  quality, 
  but 
  the 
  

   outcrops 
  were 
  too 
  obscure 
  for 
  me 
  to 
  ascertain 
  the 
  correctness 
  of 
  

   these 
  statements. 
  Stony 
  creek 
  passes 
  just 
  south 
  of 
  this 
  ridge, 
  

   and 
  on 
  the 
  opposite 
  side 
  of 
  the 
  creek 
  there 
  are 
  exposed 
  the 
  red 
  

   beds 
  of 
  the 
  Clinton 
  formation, 
  outcropping 
  over 
  the 
  point 
  of 
  the 
  

   anticlinal, 
  which 
  is 
  here 
  pitching 
  quite 
  steeply 
  to 
  the 
  northeast- 
  

   ward. 
  

  

  The 
  lower 
  Shaly 
  limestone 
  was 
  not 
  observed 
  in 
  this 
  region 
  or 
  

   southward. 
  The 
  Becraft 
  limestone 
  -was 
  seen, 
  however, 
  at 
  a 
  

   number 
  of 
  points 
  presenting 
  its 
  usual 
  characteristics 
  of 
  a 
  light- 
  

   colored, 
  semi-crystalline, 
  massively-bedded 
  limestone, 
  containing 
  

   an 
  abundance 
  of 
  fossil 
  shells. 
  Its 
  thickness 
  appears 
  to 
  be 
  con- 
  

   siderably 
  diminished, 
  although 
  no 
  complete 
  sections 
  were 
  found. 
  

   On 
  a 
  hill 
  just 
  south 
  of 
  Millhook, 
  the 
  outcrops 
  cover 
  a 
  considerable 
  

   area 
  and 
  at 
  this 
  point 
  and 
  in 
  the 
  vicinity 
  it 
  has 
  been 
  burned 
  for 
  

   lime. 
  The 
  Oriskany 
  sandstone 
  is 
  exposed 
  at 
  Millhook 
  at 
  the 
  

   milldam. 
  It 
  consists 
  of 
  a 
  very 
  dark 
  silicious 
  limestone 
  below 
  

   with 
  dark 
  quartzites 
  above. 
  At 
  the 
  locality 
  above 
  referred 
  to, 
  

   southeast 
  of 
  Kripple 
  Bush, 
  its 
  thickness 
  is 
  at 
  least 
  ten 
  feet 
  and 
  at 
  

   Millhook 
  it 
  is 
  about 
  the 
  same. 
  The 
  Onondaga 
  limestone 
  has 
  been 
  

   extensively 
  quarried 
  at 
  many 
  points 
  in 
  this 
  valley, 
  between 
  Stone 
  

   ridge 
  and 
  Kripple 
  Bush, 
  at 
  Whitfield, 
  about 
  Pattankunk, 
  at 
  

   Wawarsing 
  and 
  near 
  Napanoch. 
  The 
  formation 
  is, 
  as 
  usual, 
  a 
  

   light-colored, 
  relatively 
  pure 
  limestone, 
  with 
  occasional 
  lenses 
  

   and 
  irregular 
  layers 
  of 
  flint. 
  It 
  yields 
  an 
  excellent 
  lime 
  and 
  

   would 
  furnish 
  fine 
  building 
  stone 
  in 
  localities 
  where 
  there 
  is 
  a 
  

   sufficient 
  thickness 
  of 
  beds 
  free 
  from 
  chert. 
  A 
  mile 
  northwest 
  

   of 
  Pine 
  Bush, 
  on 
  Mombaccus 
  creek, 
  the 
  contact 
  of 
  the 
  Esopus 
  

   shales 
  and 
  the 
  Onondaga 
  limestones 
  is 
  exposed.
