  Museum. 
  

  

  a 
  point 
  on 
  the 
  northern 
  shore 
  of 
  the 
  fourth 
  Binnewater, 
  where 
  

   the 
  upper 
  Shaly 
  and 
  Oriskany 
  members 
  are 
  flexed 
  in 
  a 
  graceful 
  

   arch. 
  This 
  flexure 
  merges 
  into 
  the 
  general 
  anticlinal 
  south 
  of 
  

   here 
  and 
  is 
  lost. 
  To 
  the 
  west 
  of 
  this 
  flexure 
  there 
  is 
  a 
  synclinal 
  

   holding 
  a 
  very 
  narrow 
  ridge 
  of 
  Esopus 
  shales 
  which 
  extends 
  to 
  a 
  

   point 
  nearly 
  west 
  of 
  Binnewater 
  station. 
  West 
  of 
  this 
  synclinal 
  

   there 
  is 
  an 
  anticlinal 
  of 
  considerable 
  prominence. 
  It 
  brings 
  up 
  

   the 
  Oriskany 
  in 
  a 
  symmetrically 
  rounded 
  ridge 
  in 
  a 
  depression 
  

   amid 
  the 
  Esopus 
  ridges, 
  in 
  the 
  fork 
  of 
  the 
  roads 
  a 
  mile 
  and 
  a 
  

   half 
  due 
  west 
  of 
  Whiteport. 
  This 
  ridge 
  rises 
  gradually 
  south- 
  

   ward, 
  and 
  in 
  a 
  half 
  mile 
  the 
  Oriskany 
  is 
  eroded 
  through 
  on 
  the 
  

   summit 
  and 
  the 
  upper 
  Shaly 
  and 
  Becraft 
  limestones 
  constitute 
  

   its 
  crests 
  to 
  beyond 
  the 
  road, 
  from 
  Binnewater 
  station 
  to 
  Cotte- 
  

   kill. 
  Its 
  structure 
  is 
  shown 
  on 
  the 
  left 
  end 
  of 
  the 
  section 
  in 
  

   figure 
  7. 
  

  

  Roridout 
  creek 
  crosses 
  these 
  flexures 
  above 
  Rosendale, 
  and 
  

   the 
  lower 
  limestones 
  and 
  the 
  cement 
  beds 
  are 
  extensively 
  

   exposed 
  along 
  its 
  northern 
  bank. 
  The 
  first 
  synclinal 
  west 
  of 
  

   Rosendale 
  is 
  the 
  one 
  that 
  holds 
  the 
  long, 
  narrow 
  ridge 
  of 
  

   Esopus 
  shales 
  northwest 
  of 
  Binnewater 
  station. 
  It 
  is 
  a 
  shallow 
  

   basin 
  in 
  the 
  cement 
  rock, 
  of 
  which 
  the 
  bottom 
  is 
  near 
  the 
  level 
  

   of 
  the 
  creek, 
  and 
  the 
  beds 
  have 
  been 
  worked 
  to 
  a 
  considerable 
  

   extent 
  down 
  both 
  the 
  slopes. 
  On 
  its 
  western 
  limb 
  there 
  is 
  a 
  

   small 
  local 
  fault 
  which 
  offsets 
  the 
  cement 
  beds 
  a 
  few 
  yards. 
  Its 
  

   relations 
  are 
  shown 
  in 
  the 
  fourth 
  section, 
  on 
  plate 
  7. 
  In 
  the 
  

   anti-linal 
  next 
  west 
  the 
  Shawangunk 
  grit 
  rises 
  forty 
  feet 
  above 
  

   the 
  creek 
  bed 
  and 
  extends 
  up 
  the 
  Cottekill. 
  The 
  cement 
  beds 
  

   and 
  underlying 
  formations 
  are 
  exposed 
  on 
  both 
  flanks 
  of 
  the 
  

   flexures 
  aad 
  they 
  cross 
  the 
  kill 
  in 
  succession 
  a 
  short 
  distance 
  

   above 
  its 
  mouth. 
  

  

  West 
  of 
  these 
  flexures 
  there 
  are 
  several 
  others 
  which 
  rise 
  in 
  

   the 
  region 
  about 
  Cottekill 
  post-office 
  and 
  are 
  of 
  considerable 
  

   prominence 
  in 
  the 
  Rondout 
  valley, 
  as 
  shown 
  to 
  the 
  left 
  of 
  the 
  

   middle 
  of 
  the 
  fourth 
  section 
  on 
  plate 
  7. 
  They 
  comprise 
  two 
  

   principal 
  anticlinals, 
  of 
  which 
  the 
  easternmost 
  crosses 
  Ron- 
  

   dout 
  creek 
  at 
  the 
  mouth 
  of 
  the 
  Coxingkill 
  and 
  the 
  west- 
  

   ernmost 
  at 
  the 
  big 
  bend 
  west 
  of 
  the 
  turnpike 
  bridge. 
  The 
  

   arch 
  of 
  the 
  latter 
  anticlinal 
  is 
  superbly 
  exposed 
  in 
  cliffs 
  of
