  the 
  streams. 
  They 
  dip 
  steeply 
  to 
  the 
  west-northwest 
  about 
  

   Ellenville 
  and 
  Napanoch, 
  but 
  this 
  dip 
  gradually 
  decreases 
  both 
  

   to 
  the 
  north 
  and 
  to 
  the 
  west. 
  

  

  At 
  Honk 
  falls 
  there 
  is 
  a 
  fine 
  exhibition 
  of 
  the 
  steep 
  dipping 
  

   flaggy 
  beds 
  and 
  this 
  feature 
  is 
  shown 
  in 
  plate 
  20. 
  

  

  The 
  dip 
  at 
  this 
  locality 
  is 
  about 
  forty-five 
  degrees, 
  a 
  mile 
  and 
  

   a 
  half 
  west 
  it 
  is 
  thirty 
  degrees, 
  and 
  in 
  the 
  upper 
  flag 
  series, 
  two 
  

   and 
  a 
  half 
  miles 
  above 
  the 
  falls, 
  it 
  has 
  decreased 
  to 
  ten 
  degrees 
  ; 
  

   at 
  Lackawack 
  it 
  is 
  not 
  over 
  three 
  degrees. 
  

  

  The 
  Catskill 
  Mountain 
  Region. 
  

  

  The 
  Catskill 
  mountains 
  consist 
  of 
  a 
  great 
  thickness 
  of 
  sand- 
  

   stones 
  and 
  shales, 
  dipping 
  gently 
  to 
  the 
  westward. 
  These 
  

   members 
  comprise 
  the 
  greater 
  part 
  of 
  the 
  upper 
  flag 
  forma- 
  

   tion, 
  overlaid 
  by 
  the 
  red 
  conglomeratic 
  sandstones 
  which 
  con 
  

   stitute 
  the 
  higher 
  portions 
  of 
  the 
  Slide 
  mountain 
  range 
  and 
  

   extend 
  westward 
  over 
  the 
  high 
  ridges 
  between 
  the 
  west 
  

   branch 
  of 
  the 
  JSTeversink 
  and 
  the 
  Delaware 
  county 
  line. 
  

   There 
  are 
  also 
  on 
  the 
  very 
  high 
  summits 
  of 
  the 
  Slide 
  moun- 
  

   tain 
  range 
  the 
  light-colored, 
  conglomeratic 
  sandstones. 
  In 
  the 
  

   mountains 
  north 
  of 
  Esopus 
  creek 
  the 
  conglomeratic 
  members 
  

   are 
  not 
  represented, 
  although 
  there 
  are 
  occasionally 
  intercalated, 
  

   at 
  somewhat 
  lower 
  horizons, 
  thin 
  streaks 
  of 
  a 
  conglomeratic 
  

   character. 
  The 
  idea 
  which 
  has 
  so 
  long 
  prevailed 
  that 
  the 
  

   higher 
  peaks 
  of 
  the 
  Catskiils 
  are 
  capped 
  hj 
  remnants 
  of 
  a 
  

   great 
  sheet 
  of 
  conglomerate 
  is 
  erroneous, 
  at 
  least 
  in 
  the 
  Ulster 
  

   county 
  region, 
  for 
  the 
  conglomerates 
  are 
  in 
  streaks 
  and 
  at 
  sev- 
  

   eral 
  different 
  horizons. 
  The 
  stratigraphy 
  of 
  the 
  Catskill 
  region 
  

   is 
  not 
  uniform 
  throughout 
  and 
  there 
  are 
  variations 
  in 
  the 
  char 
  

   acters 
  of 
  the 
  beds 
  in 
  different 
  districts. 
  The 
  greater 
  part 
  of 
  the 
  

   lower 
  series 
  contains 
  flagstone 
  beds 
  of 
  great 
  extent 
  which 
  have 
  

   been 
  quarried 
  at 
  a 
  number 
  of 
  localities 
  along 
  Esopus 
  creek 
  and 
  

   its 
  branches 
  and 
  along 
  the 
  eastern 
  front 
  of 
  the 
  mountains. 
  

   . 
  The 
  flags 
  occur 
  at 
  various 
  horizons, 
  but 
  the 
  beds 
  do 
  not 
  appear 
  

   to 
  be 
  constant 
  in 
  character 
  throughout. 
  It 
  is 
  exceedingly 
  

   difficult 
  to 
  trace 
  them 
  for 
  any 
  great 
  distance, 
  owing 
  to 
  talus 
  on 
  

   the 
  slopes. 
  The 
  intercalated 
  red 
  shales 
  occur 
  in 
  greatest 
  force 
  

   in 
  the 
  lower 
  members, 
  where 
  they 
  are 
  numerous 
  and 
  thick. 
  They 
  

   are 
  not 
  continuous 
  beds 
  but 
  give 
  place 
  to 
  flags, 
  in 
  some 
  cases 
  very
