  Report

  the 
  State 
  Museum. 
  

  

  At 
  the 
  head 
  of 
  the 
  lake 
  and 
  the 
  base 
  of 
  the 
  south 
  end 
  of 
  the 
  

   mass 
  of 
  grit 
  at 
  Platz 
  point 
  the 
  Hudson 
  river 
  shales 
  constitute 
  a 
  

   small 
  plateau 
  which 
  surmounts 
  the 
  long 
  eastern 
  slope 
  of 
  the 
  

   mountain. 
  There 
  is 
  no 
  cross 
  drainage 
  way 
  at 
  the 
  base 
  of 
  the 
  

   cliff, 
  and 
  the 
  cause 
  of 
  the 
  abrupt 
  termination 
  of 
  this 
  point 
  is 
  diffi- 
  

   cult 
  to 
  understand. 
  

  

  The 
  grit 
  dips 
  gently 
  to 
  the 
  west 
  northwest 
  along 
  the 
  west 
  side 
  

   of 
  Paltz 
  point 
  and 
  very 
  slightly 
  to 
  the 
  eastward 
  in 
  the 
  eastern- 
  

   most 
  part 
  of 
  the 
  range. 
  Northeast 
  of 
  the 
  lake 
  the 
  dip 
  is 
  at 
  a 
  low 
  

   angle 
  to 
  the 
  westward, 
  but 
  there 
  are 
  several 
  slight 
  undulations. 
  

   There 
  is 
  everywhere 
  a 
  pronounced 
  pitch 
  to 
  the 
  northwest. 
  Owing 
  

   to 
  the 
  westerly 
  dip 
  the 
  grits 
  in 
  the 
  Paltz 
  point 
  ridge 
  are 
  some- 
  

   what 
  lower 
  just 
  north 
  of 
  the 
  lake 
  than 
  elsewhere. 
  It 
  will 
  be 
  

   seen 
  from 
  these 
  statements 
  that 
  the 
  lake 
  lies 
  slightly 
  west 
  of 
  the 
  

   center 
  of 
  the 
  a,rch 
  of 
  the 
  anticlinal 
  and 
  all 
  the 
  dips 
  along 
  its 
  

   shores 
  are 
  to 
  the 
  northwest 
  although 
  at 
  very 
  low 
  angles. 
  The 
  

   degree 
  of 
  dip 
  rapidly 
  increases 
  down 
  the 
  western 
  slope 
  of 
  the 
  

   mountain 
  to 
  the 
  synclinal 
  valley 
  of 
  the 
  Coxingkill. 
  

  

  The 
  outlet 
  of 
  Lake 
  Mohonk 
  is 
  to 
  the 
  northward 
  by 
  a 
  branch 
  of 
  

   the 
  Coxingkill. 
  This 
  branch 
  flows 
  through 
  a 
  slight 
  depression 
  

   separating 
  the 
  Paltz 
  point 
  range 
  from 
  the 
  main 
  mountain 
  mass, 
  

   and 
  then 
  obliquely 
  down 
  the 
  flank 
  of 
  the 
  anticlinal. 
  

  

  South 
  from 
  Paltz 
  point 
  the 
  eastern 
  front 
  of 
  the 
  mountain 
  pre- 
  

   sents 
  a 
  nearly 
  unbroken 
  line 
  of 
  cliffs 
  for 
  many 
  miles 
  along 
  or 
  

   near 
  the 
  crest 
  of 
  the 
  anticline. 
  The 
  nature 
  of 
  a 
  portion 
  of 
  the 
  

   escarpment 
  is 
  shown 
  in 
  plate 
  17. 
  

  

  Two 
  miles 
  south 
  of 
  Lake 
  Mohonk 
  there 
  is 
  a 
  slight 
  depression 
  

   in 
  the 
  crest 
  line 
  through 
  which 
  the 
  road 
  to 
  Lake 
  Minnewaska 
  

   passes 
  and 
  there 
  are 
  several 
  other 
  depressions 
  of 
  less 
  amount. 
  

   Millbrook 
  mountain 
  is 
  the 
  culminating 
  feature 
  of 
  the 
  portion 
  of 
  

   the 
  range 
  beyond 
  which 
  its 
  front 
  is 
  somewhat 
  more 
  irregular 
  in 
  

   contour. 
  

  

  Lake 
  Minnewaska 
  is 
  similar 
  to 
  Lake 
  Mohonk 
  in 
  appearance, 
  

   but 
  it 
  is 
  somewhat 
  larger. 
  It 
  was 
  not 
  ascertained 
  whether 
  its 
  

   basin 
  extends 
  into 
  the 
  Hudson 
  river 
  shales, 
  for 
  there 
  is 
  a 
  con- 
  

   tinuous 
  rim 
  of 
  grit 
  surrounding 
  it. 
  As 
  a 
  very 
  great 
  thickness 
  of 
  

   grit 
  is 
  exposed 
  above 
  the 
  water 
  level 
  in 
  this 
  vicinity 
  it 
  seems 
  

   probable 
  that 
  the 
  bottom 
  of 
  the 
  lake 
  is 
  very 
  near 
  the 
  shales. 
  

   This 
  probability 
  is 
  increased 
  somewhat 
  by 
  the 
  presence 
  of 
  the
