  Report 
  on 
  the 
  State 
  Museum. 
  

  

  from 
  the 
  exposure 
  above 
  described. 
  The 
  quartzite 
  member 
  is 
  

   here 
  about 
  twenty 
  feet 
  thick 
  and 
  well 
  characterized. 
  Flesh, 
  buff 
  

   and 
  pink 
  tints 
  prevail, 
  alternating 
  in 
  thick 
  beds 
  or 
  ribbonings, 
  

   and 
  also 
  in 
  cross-bedding 
  within 
  the 
  beds. 
  The 
  shaly 
  member 
  

   has 
  a 
  thickness 
  of 
  about 
  twenty 
  feet, 
  and 
  is 
  quite 
  a 
  bright 
  red 
  

   shale, 
  lying 
  on 
  the 
  Shawangunk 
  grit. 
  The 
  formation 
  comes 
  up 
  

   again 
  a 
  short 
  distance 
  north, 
  where 
  the 
  shales 
  are 
  seen 
  to 
  be 
  

   darker 
  in 
  color 
  and 
  considerably 
  thicker. 
  

  

  In 
  the 
  immediate 
  vicinity 
  of 
  Kosendale 
  the 
  quartzite 
  is 
  often 
  

   exposed 
  in 
  and 
  near 
  the 
  cement 
  quarries, 
  of 
  which 
  it 
  is 
  the 
  floor, 
  

   and 
  it 
  has 
  the 
  same 
  characteristics 
  as 
  above 
  described. 
  The 
  red 
  

   shale 
  is 
  less 
  frequently 
  exposed, 
  for 
  Hondout 
  creek 
  runs 
  along 
  

   its 
  outcrop 
  line 
  for 
  some 
  distance, 
  and 
  it 
  is 
  much 
  covered 
  by 
  

   talus 
  elsewhere. 
  

  

  In 
  the 
  banks 
  just 
  below 
  the 
  High 
  falls 
  on 
  the 
  Rondout 
  there 
  is 
  

   a 
  fine 
  exposure 
  of 
  the 
  rock 
  of 
  this 
  horizon. 
  The 
  quartzitic 
  mem- 
  

   ber 
  is 
  seen 
  to 
  have 
  increased 
  in 
  thickness 
  somewhat, 
  and 
  has 
  

   given 
  place 
  to 
  gray 
  sandstone 
  containing 
  intercalations 
  of 
  re'd, 
  

   gray 
  and 
  buff 
  shales. 
  The 
  shale 
  member 
  below 
  has 
  a 
  thickness 
  

   of 
  about 
  twenty-five 
  feet, 
  and 
  consists 
  of 
  gray 
  shales 
  above 
  and 
  

   red 
  shales 
  below, 
  with 
  intercalated 
  buff 
  and 
  greenish 
  shales 
  and 
  

   sandstones. 
  

  

  In 
  the 
  synclinal 
  area, 
  two 
  miles 
  southeast 
  of 
  High 
  falls, 
  bright 
  

   red 
  shales 
  are 
  seen 
  in 
  the 
  lower 
  portion 
  of 
  the 
  formation. 
  The 
  

   overlying 
  beds 
  were 
  not 
  observed. 
  These 
  red 
  shales 
  are 
  again 
  

   exposed 
  at 
  the 
  end 
  of 
  the 
  anticlinal 
  just 
  southeast 
  of 
  Port 
  Jack- 
  

   son. 
  Along 
  the 
  base 
  of 
  the 
  western 
  slope 
  of 
  the 
  Shawangunk 
  

   mountain 
  to 
  Eilenville 
  and 
  beyond, 
  I 
  have 
  seen 
  but 
  few 
  outcrops. 
  

   Those 
  which 
  I 
  have 
  observed 
  at 
  this 
  horizon 
  were 
  of 
  red 
  and 
  

   brown 
  shales, 
  lying 
  low 
  on 
  the 
  slope 
  or 
  at 
  the 
  creek 
  bed. 
  

  

  Shawangunk 
  grit 
  — 
  This 
  formation 
  is 
  a 
  great 
  sheet 
  of 
  silicified 
  

   quartz 
  conglomerate 
  lying 
  on 
  the 
  Hudson 
  river 
  shales 
  and 
  giving 
  

   rise 
  to 
  the 
  Shawangunk 
  mountain. 
  The 
  first 
  appearance 
  of 
  the 
  

   formation 
  northward 
  is 
  between 
  Binne 
  water 
  and 
  Whiteport, 
  and 
  

   in 
  the 
  cement 
  quarries 
  on 
  the 
  eastern 
  side 
  of 
  the 
  ridge, 
  as 
  before 
  

   noted. 
  In 
  the 
  anticlinal, 
  north 
  of 
  Binne 
  water, 
  the 
  thickness 
  

   rapidly 
  increases 
  to 
  sixty 
  feet, 
  but 
  to 
  the 
  eastward 
  it 
  thickens 
  

   less 
  rapidly 
  and 
  it 
  is 
  discontinuous 
  at 
  several 
  points. 
  Just 
  south 
  

   of 
  Rosendale 
  it 
  thickens 
  rapidly 
  from 
  east 
  to 
  west 
  to 
  about 
  forty-
