  of 
  the 
  lake, 
  passes 
  over 
  the 
  edge 
  of 
  the 
  grit 
  in 
  a 
  series 
  of 
  falls, 
  

   and 
  has 
  cut 
  a 
  deep 
  gorge 
  into 
  the 
  Hudson 
  river 
  shales 
  below. 
  

  

  Lake 
  Awosting 
  is 
  the 
  largest 
  lake 
  of 
  the 
  series 
  and 
  is 
  a 
  con- 
  

   siderable 
  body 
  of 
  water. 
  It 
  is 
  mostly 
  surrounded 
  by 
  low 
  cliffs 
  

   and 
  rocky 
  slopes, 
  but 
  near 
  its 
  eastern 
  end 
  there 
  is 
  a 
  very 
  high 
  

   cliff 
  for 
  some 
  distance 
  which 
  comes 
  in 
  from 
  the 
  crest 
  of 
  the 
  moun- 
  

   tain 
  eastward 
  and 
  constitutes 
  a 
  high 
  west-sloping 
  plateau 
  north- 
  

   east 
  of 
  the 
  lake. 
  

  

  In 
  the 
  following 
  figure 
  there 
  is 
  given 
  a 
  view 
  of 
  this 
  lake, 
  based 
  

   on 
  a 
  kodak 
  photograph.

  Awosting

  The 
  basin 
  of 
  this 
  lake 
  does 
  not 
  appear 
  to 
  be 
  in 
  Hudson 
  river 
  

   shales, 
  though 
  possibly 
  they 
  underlie 
  its 
  deeper 
  portions. 
  The 
  

   grit 
  dips 
  gently 
  west 
  along 
  the 
  shores, 
  and 
  this 
  dip 
  continues 
  over 
  

   a 
  wide 
  area. 
  To 
  the 
  west 
  is 
  a 
  long 
  slope 
  which 
  extends 
  from 
  a 
  

   low 
  cliff 
  along 
  the 
  lake 
  to 
  the 
  main 
  Peterkill 
  or 
  Yly 
  Creek 
  valley. 
  

  

  The 
  outlet 
  of 
  the 
  lake 
  is 
  by 
  a 
  branch 
  of 
  the 
  Peterkill 
  which 
  

   flows 
  along 
  the 
  west 
  sloping 
  grits 
  for 
  a 
  mile 
  and 
  then 
  passes 
  over 
  

   high 
  falls 
  into 
  the 
  main 
  valley 
  of 
  the 
  Peterkill. 
  To 
  the 
  east 
  of 
  

   the 
  confluence 
  there 
  is 
  a 
  narrow 
  depression 
  known 
  as 
  the 
  " 
  dark 
  

   hole," 
  which 
  extends 
  southeastward 
  up 
  the 
  slope 
  of 
  the 
  moun- 
  

   tain. 
  It 
  is 
  bordered 
  by 
  moderately 
  high 
  cliffs 
  of 
  east-dipping 
  

   grits 
  and 
  was 
  cut 
  by 
  a 
  stream 
  which 
  empties 
  into 
  the 
  Peterkill. 
  

   On 
  its 
  south 
  side 
  is 
  the 
  high 
  plateau 
  of 
  which 
  the 
  eastern 
  front 
  

   is 
  the 
  cliff 
  at 
  the 
  southeast 
  end 
  of 
  Lake 
  Awosting. 
  Its 
  relations 
  

   are 
  shown 
  in 
  the 
  stereogramic 
  map. 
  

  

  The 
  Peterkill 
  valley, 
  from 
  beginning 
  to 
  end, 
  flows 
  on 
  the 
  

   western 
  flank 
  of 
  the 
  anticlinal 
  on 
  which 
  Lake 
  Minnewaska 
  is 
  

   situated. 
  It 
  has 
  a 
  cliff 
  of 
  west-dipping 
  grit 
  along 
  its 
  west 
  side
