  Report

  State 
  Museum. 
  

  

  South 
  of 
  the 
  line 
  of 
  section 
  IV 
  (plate 
  4) 
  the 
  dips 
  gradually 
  

   decrease 
  to 
  fifty 
  degrees. 
  In 
  about 
  half 
  a 
  mile 
  the 
  ridge 
  narrows 
  

   and 
  ends, 
  and 
  to 
  the 
  southward 
  for 
  some 
  distance 
  there 
  are 
  low 
  

   lands 
  and 
  sand-covered 
  slopes, 
  in 
  greater 
  part 
  occupied 
  by 
  the 
  

   buildings 
  of 
  Kondout, 
  an 
  area 
  in 
  which 
  there 
  are 
  no 
  exposures. 
  

   In 
  the 
  interval 
  to 
  Kondout 
  creek 
  there 
  are 
  several 
  outcrops 
  of 
  

   Hudson 
  river 
  sandstone 
  along 
  the 
  slopes 
  just 
  south 
  of 
  the 
  main 
  

   street, 
  and 
  a 
  small 
  showing 
  of 
  the 
  upper 
  and 
  lower 
  Shaly 
  beds 
  

   and 
  intervening 
  Becraft 
  limestone, 
  a 
  short 
  way 
  beyond. 
  These 
  

   members 
  and 
  the 
  underlying 
  limestones 
  and 
  cement 
  beds 
  cross 
  

   the 
  Kondout 
  creek 
  half 
  a 
  mile 
  northeast 
  of 
  the 
  West 
  Shore 
  rail- 
  

   way 
  bridge 
  and 
  rise 
  high 
  in 
  the 
  bank 
  on 
  the 
  south 
  side 
  of 
  the 
  

   creek. 
  The 
  Oriskany 
  beds 
  do 
  not 
  cross 
  the 
  -creek 
  but 
  extend 
  

   -along 
  the 
  west 
  bank 
  on 
  a 
  long 
  slope 
  surmounted 
  by 
  Esopus 
  shales. 
  

   The 
  conglomerate 
  before 
  described 
  is 
  a 
  conspicuous 
  feature 
  of 
  

   this 
  exposure, 
  and 
  its 
  area 
  is 
  extended 
  somewhat 
  by 
  a 
  small 
  syn- 
  

   clinal 
  extending 
  along 
  the 
  base 
  of 
  the 
  slope. 
  To 
  the 
  south 
  the 
  

   Oriskany 
  beds 
  ipitch 
  downward 
  somewhat, 
  and 
  the 
  overlying 
  

   Esopus 
  shales 
  constitute 
  the 
  high 
  bank 
  for 
  a 
  short 
  distance. 
  They 
  

   lie 
  in 
  a 
  broad, 
  gentle 
  synclinal 
  which 
  pitches 
  gently 
  to 
  the 
  

   northward. 
  

  

  Approaching 
  the 
  railroad 
  bridge 
  a 
  series 
  of 
  flexures 
  come 
  in 
  

   which 
  carry 
  the 
  Oriskany 
  and 
  Esopus 
  beds 
  westward 
  and 
  bring 
  

   up 
  the 
  underlying 
  limestones. 
  They 
  are 
  finely 
  exposed 
  under 
  

   the 
  bridge 
  and 
  to 
  Wilbur, 
  in 
  cliffs 
  rising 
  high 
  on 
  both 
  sides 
  of 
  

   the 
  creek. 
  The 
  relations 
  at 
  this 
  point 
  are 
  shown 
  in 
  the 
  following 
  

   section 
  taken 
  from 
  Davis's 
  paper.

  The 
  lower 
  Shaly 
  and 
  Pentamerus 
  beds 
  are 
  the 
  most 
  conspicu- 
  

   ous 
  features 
  in 
  these 
  exposures, 
  and 
  they 
  are 
  finely 
  exhibited. 
  

   The 
  Becraft 
  beds 
  are 
  high 
  in 
  the 
  adjoining 
  slopes, 
  where 
  they 
  

   have 
  been 
  extensively 
  quarried 
  for 
  lime 
  burning.
