  and 
  long 
  slopes 
  of 
  grit 
  to 
  the 
  east. 
  Four 
  miles 
  below 
  Lake 
  

   Awosting 
  the 
  kill 
  passes 
  over 
  "Awosting 
  falls 
  " 
  and 
  then 
  over 
  a 
  

   series 
  of 
  cascades 
  aggregating 
  in 
  all 
  a 
  fall 
  of 
  240 
  feet 
  (approxi- 
  

   mated). 
  In 
  the 
  Awosting 
  falls 
  there 
  is 
  a 
  clear 
  drop 
  of 
  sixty 
  or 
  

   more 
  feet. 
  In 
  plate 
  19 
  these 
  falls 
  are 
  shown. 
  They 
  are 
  a 
  mile 
  

   north 
  of 
  Lake 
  Minnewaska 
  and 
  are 
  an 
  attractive 
  feature 
  of 
  that 
  

   resort. 
  

  

  In 
  the 
  bottom 
  of 
  the 
  gorge 
  below 
  the 
  several 
  falls 
  there 
  are 
  

   high 
  cliffs 
  of 
  grit 
  for 
  some 
  distance. 
  Owing 
  to 
  a 
  considerable 
  

   pitch 
  to 
  the 
  north, 
  or 
  down 
  stream, 
  and 
  a 
  thickness 
  of 
  grit 
  some- 
  

   what 
  over 
  200 
  feet, 
  the 
  falls 
  of 
  this 
  series 
  do 
  not 
  cut 
  through 
  to 
  

   the 
  Hudson 
  river 
  slates. 
  

  

  South 
  of 
  Lake 
  Awosting 
  there 
  are 
  two 
  small 
  ponds 
  on 
  the 
  

   summit 
  of 
  the 
  mountain, 
  but 
  I 
  did 
  not 
  visit 
  them. 
  Mud 
  pond 
  is 
  

   one, 
  at 
  the 
  head 
  of 
  Yly 
  Creek 
  or 
  the 
  principal 
  branch 
  of 
  the 
  

   Peterkill, 
  and 
  Lake 
  Maratanza 
  is 
  the 
  other. 
  Lake 
  Maratanza 
  

   empties 
  to 
  the 
  east 
  by 
  a 
  branch 
  of 
  the 
  Wallkill, 
  which 
  pitches 
  

   over 
  the 
  edge 
  of 
  the 
  mountain 
  a 
  short 
  distance 
  from 
  the 
  lake 
  in 
  

   a 
  great 
  fall, 
  and 
  into 
  a 
  deep 
  gulf 
  of 
  Hudson 
  river 
  shales. 
  The 
  

   locality 
  is 
  known 
  as 
  Yerkeeder 
  falls 
  and 
  it 
  is 
  said 
  to 
  be 
  a 
  very 
  

   fine 
  feature. 
  

  

  Between 
  Gertrude's 
  nose 
  and 
  Sam's 
  point 
  the 
  crest 
  of 
  the 
  

   mountain 
  u 
  very 
  high, 
  but 
  for 
  some 
  distance 
  the 
  edge 
  of 
  the 
  

   grit 
  is 
  broken 
  into 
  great 
  terraces, 
  and 
  there 
  is 
  a 
  sloping 
  bench 
  of 
  

   Hudson 
  river 
  shales 
  of 
  some 
  width 
  at 
  their 
  base. 
  Several 
  

   branches 
  of 
  Walkill 
  drainage 
  head 
  in 
  the 
  crest 
  of 
  the 
  mountain 
  

   in 
  this 
  region 
  and 
  pnss 
  over 
  the 
  edge 
  of 
  the 
  grit 
  in 
  falls, 
  of 
  which 
  

   the 
  above-mentioned 
  Yerkeeder 
  falls 
  are 
  the 
  most 
  noteworthy. 
  

  

  In 
  this 
  region 
  the 
  mountain 
  continues 
  to 
  narrow 
  and 
  most 
  of 
  

   the 
  flexures 
  pass 
  out 
  to 
  the 
  southward. 
  ' 
  This 
  narrowing 
  is 
  due 
  to 
  

   the 
  recession 
  of 
  the 
  edge 
  of 
  the 
  sheet 
  of 
  the 
  Shawangunk 
  grit 
  

   and 
  is 
  closely 
  related 
  to 
  the 
  upward 
  pitch 
  of 
  the 
  flexures. 
  This 
  

   pitch 
  increases 
  the 
  height 
  of 
  the 
  mountain 
  southward, 
  but 
  with 
  

   increased 
  height 
  there 
  is 
  a 
  corresponding 
  increase 
  of 
  erosion 
  in 
  

   the 
  soft 
  underlying 
  shales, 
  which 
  beyond 
  certain 
  limits 
  causes 
  

   rapid 
  recession. 
  This 
  is 
  illustrated 
  by 
  Sam's 
  point, 
  where 
  the 
  

   maximum 
  altitude 
  of 
  2200 
  feet 
  is 
  attained. 
  The 
  u 
  point" 
  is 
  

   a 
  narrowing 
  extension 
  of 
  the 
  grit 
  along 
  the 
  axis 
  of 
  a 
  very 
  flat 
  

   synclinal, 
  which 
  finally 
  terminates 
  in 
  a 
  high 
  narrow 
  cliff 
  pre-
