  synclinal. 
  Lake 
  Minnewaska 
  is 
  in 
  the 
  crown 
  of 
  the 
  anti- 
  

   clinal, 
  which 
  rises 
  at 
  High 
  Falls, 
  and 
  Lake 
  Awosting 
  is 
  on 
  the 
  

   western 
  slope 
  of 
  the 
  same 
  flexure. 
  

  

  These 
  lakes 
  are 
  all 
  situated 
  near 
  the 
  eastern 
  side 
  of 
  

   the 
  mountain 
  and 
  about 
  150 
  feet 
  below 
  the 
  crest. 
  They 
  are 
  

   similar 
  in 
  relations 
  and 
  originated 
  under 
  almost 
  the 
  same 
  

   conditions. 
  Lake 
  Mohonk 
  occupies 
  a 
  north 
  and 
  south 
  cleft 
  

   in 
  the 
  crown 
  of 
  the 
  anticlinal 
  which 
  rises 
  at 
  Rosendale. 
  

  

  The 
  structure 
  of 
  the 
  lake 
  is 
  shown 
  in 
  the 
  following

  The 
  lake 
  basin 
  is 
  in 
  Hudson 
  river 
  shales 
  but 
  it 
  is 
  surrounded 
  on 
  

   the 
  east 
  and 
  west 
  by 
  high 
  cliffs 
  of 
  Shawangunk 
  grits. 
  To 
  the 
  

   south 
  there 
  is 
  a 
  gap 
  in 
  the 
  front 
  of 
  the 
  mountain 
  through 
  which 
  

   the 
  shales 
  extend 
  to 
  the 
  lake. 
  The 
  top 
  of 
  these 
  shales 
  is 
  a 
  few 
  

   feet 
  above 
  the 
  surface 
  of 
  the 
  lake 
  at 
  its 
  southeast 
  end 
  but 
  the 
  

   pitch 
  carries 
  them 
  a 
  few 
  feet 
  below 
  the 
  water 
  surface 
  to 
  the 
  

   north 
  and 
  west. 
  

  

  The 
  view 
  in 
  plate 
  16 
  is 
  looking 
  southward 
  and 
  through 
  the 
  gap 
  

   in 
  the 
  east 
  front 
  of 
  the 
  mountain 
  through 
  which 
  the 
  Hudson 
  

   river 
  shales 
  extend 
  to 
  the 
  lake. 
  On 
  the 
  left 
  is 
  Paltz 
  point 
  and 
  

   to 
  the 
  right 
  in 
  the 
  distance 
  there 
  is 
  " 
  Cope 
  point 
  " 
  a 
  projection 
  

   of 
  the 
  southern 
  extension 
  of 
  the 
  eastern 
  front 
  of 
  the 
  mountain. 
  

  

  East 
  of 
  the 
  lake 
  there 
  is 
  a 
  thick 
  mass 
  of 
  grit 
  which 
  lies 
  along 
  

   the 
  crest 
  of 
  the 
  anticlinal. 
  It 
  begins 
  a 
  short 
  distance 
  north 
  and 
  

   is 
  terminated 
  by 
  very 
  abrupt 
  cliffs 
  in 
  Paltz 
  point 
  near 
  the 
  

   southern 
  end 
  of 
  the 
  lake. 
  The 
  character 
  of 
  this 
  " 
  point 
  " 
  is 
  shown 
  

   in 
  plate 
  16, 
  and 
  its 
  relations 
  are 
  represented 
  in 
  the 
  stereogramic 
  

  

  map.
