  Report 
  on 
  the 
  State 
  Museum. 
  

  

  The 
  Onondaga 
  limestone, 
  west 
  of 
  Saugerties, 
  extends 
  along 
  the 
  

   road 
  from 
  Mt. 
  Marion 
  to 
  Asbury 
  in 
  a 
  belt 
  averaging 
  a 
  

   quarter 
  of 
  a 
  mile 
  wide, 
  lying 
  on 
  the 
  eastern 
  slope 
  of 
  the 
  Beaver- 
  

   kill 
  valley. 
  Exposures 
  are 
  almost 
  continuous 
  and 
  some 
  interest- 
  

   ing 
  features 
  are 
  presented. 
  The 
  most 
  prominent 
  outcrop 
  is 
  a 
  

   line 
  of 
  low 
  picturesque 
  cliffs 
  extending 
  along 
  the 
  road 
  for 
  some 
  

   distance 
  south 
  from 
  Katsbaan. 
  The 
  limestone 
  has 
  been 
  employed 
  

   at 
  several 
  points 
  for 
  the 
  manufacture 
  of 
  lime 
  for 
  local 
  use. 
  Near 
  

   the 
  road-forks 
  west 
  of 
  Saugerties 
  station 
  there 
  is 
  a 
  quarry 
  in 
  beds 
  

   which 
  are 
  relatively 
  free 
  from 
  chert. 
  The 
  rock 
  is 
  moderately 
  

   hard, 
  but 
  owing 
  to 
  a 
  tendency 
  to 
  vertical 
  jointing 
  and 
  well- 
  

   developed 
  bedding 
  planes 
  it 
  is 
  easily 
  dressed. 
  Its 
  color 
  is 
  

   a 
  light 
  blue-gray 
  of 
  very 
  pleasant 
  tint. 
  The 
  available 
  beds 
  

   of 
  this 
  quarry 
  have 
  a 
  thickness 
  of 
  six 
  or 
  seven 
  feet 
  and 
  

   these 
  are 
  accessible 
  over 
  a 
  considerable 
  area. 
  A 
  short 
  distance 
  

   southwest 
  of 
  Saugerties 
  station, 
  the 
  railroad 
  passes 
  through 
  a 
  

   cut 
  in 
  the 
  lower 
  beds 
  of 
  the 
  Onondaga 
  limestone 
  and 
  runs 
  on 
  

   this 
  formation 
  from 
  there 
  to 
  Kingston. 
  The 
  relation 
  of 
  the 
  

   Esopus 
  shales 
  to 
  the 
  overlying 
  limestones 
  is 
  well 
  exhibited 
  

   in 
  this 
  railroad 
  cut. 
  The 
  black, 
  slaty 
  shales 
  become 
  lighter 
  

   colored 
  and 
  calcareous, 
  gradually 
  lose 
  their 
  cleavage 
  and 
  give 
  

   place 
  to 
  the 
  argillaceous 
  limestones 
  of 
  the 
  base 
  of 
  the 
  Onondaga. 
  

   The 
  limestones 
  are 
  exposed 
  in 
  the 
  ridge 
  east 
  of 
  the 
  railroad 
  to 
  

   Mt. 
  Marion 
  station, 
  south 
  of 
  which 
  they 
  are 
  seen 
  at 
  frequent 
  

   intervals 
  in 
  the 
  railroad 
  cuts. 
  They 
  dip 
  gently 
  to 
  the 
  westward 
  

   into 
  a 
  wide 
  valley 
  filled 
  with 
  superficial 
  formations, 
  from 
  which 
  

   the 
  Hamilton 
  shales 
  rise 
  in 
  high 
  hills 
  to 
  the 
  westward. 
  In 
  cuts 
  

   adjoining 
  the 
  railroad 
  bridge 
  over 
  Esopus 
  creek, 
  the 
  impure 
  basal 
  

   limestones 
  are 
  again 
  seen 
  overlying 
  the 
  Esopus 
  beds. 
  The 
  falls 
  of 
  

   the 
  Esopus 
  at 
  this 
  point 
  are 
  over 
  a 
  ledge 
  of 
  Onondaga 
  limestone 
  

   into 
  a 
  pool 
  excavated 
  in 
  the 
  beds 
  of 
  passage, 
  and 
  the 
  Esopus 
  

   shales 
  are 
  finely 
  exhibited 
  in 
  the 
  banks 
  below. 
  A 
  short 
  distance 
  

   south 
  of 
  the 
  falls 
  a 
  shallow 
  synclinal 
  is 
  seen 
  near 
  the 
  eastern 
  edge 
  

   of 
  the 
  limestones, 
  but 
  along 
  the 
  railroad 
  the 
  beds 
  have 
  their 
  

   usual 
  dip 
  to 
  the 
  westward 
  at 
  angles 
  of 
  from 
  three 
  to 
  fifteen 
  degrees. 
  

   Half 
  a 
  mile 
  north 
  of 
  Katrine 
  station

  cherty 
  beds

  the
