  Report

  State 
  Museum. 
  

  

  originally 
  arched. 
  Unfortunately 
  the 
  photograph 
  from 
  which 
  

   plate 
  13 
  was 
  reproduced 
  was 
  taken 
  under 
  unfavorable 
  conditions 
  

   and 
  is 
  not 
  as 
  clear 
  as 
  could 
  be 
  desired. 
  

  

  South 
  from 
  Buntico 
  point 
  the 
  eastern 
  crest 
  of 
  the 
  Shawangunk 
  

   mountain 
  consists 
  of 
  a 
  great 
  mass 
  of 
  soft 
  Hudson 
  river 
  shales 
  

   which 
  are 
  being 
  rapidly 
  and 
  deeply 
  eroded. 
  They 
  extend 
  south 
  

   nearly 
  to 
  Lake 
  Mohonk, 
  where 
  the 
  crest 
  of 
  the 
  anticlinal 
  is 
  

   occupied 
  by 
  grit 
  for 
  some 
  distance. 
  

  

  The 
  grit 
  in 
  the 
  western 
  limb 
  of 
  the 
  anticlinal 
  lies 
  along 
  the 
  

   western 
  slope 
  of 
  the 
  northern 
  end 
  of 
  the 
  mountain 
  and 
  does 
  not 
  

   attain 
  the 
  prominence 
  that 
  it 
  has 
  in 
  the 
  ridge 
  terminating 
  in 
  

   Buntico 
  point. 
  It 
  constitutes 
  a 
  monocHnal 
  ridge 
  with 
  a 
  line 
  of 
  

   cliffs 
  along 
  its 
  eastern 
  edge 
  above 
  which 
  the 
  hills 
  of 
  Hudson 
  

   river 
  slates 
  rise 
  several 
  hundred 
  feet. 
  About 
  the 
  northern 
  end 
  

   of 
  the 
  mountain 
  the 
  grit 
  of 
  this 
  monoclinal 
  extends 
  eastward 
  

   over 
  a 
  series 
  of 
  shallow 
  flexures 
  which 
  pitch 
  rapidly 
  to 
  the 
  

   northward, 
  as 
  shown 
  in 
  figure 
  11. 
  The 
  hills 
  of 
  Hudson 
  river 
  

   shales 
  sink 
  rapidly 
  in 
  this 
  portion 
  of 
  the 
  region 
  and 
  soon 
  

   give 
  place 
  to 
  a 
  rocky, 
  undulating 
  plateau 
  of 
  Shawangunk 
  grit 
  

   which 
  closes 
  over 
  the 
  end 
  of 
  the 
  anticlinal 
  in 
  the 
  vicinity 
  of 
  

   Eondout 
  creek. 
  To 
  the 
  west 
  of 
  the 
  west-dipping 
  monocline 
  of 
  

   Shawangunk 
  grit 
  there 
  is 
  the 
  synclinal 
  valley 
  of 
  the 
  Coxingkill, 
  

   containing 
  overlying 
  members 
  up 
  to 
  the 
  Pentamerus 
  limestone, 
  

   which 
  was 
  described 
  on 
  a 
  previous 
  page. 
  On 
  the 
  opposite 
  side 
  of 
  

   this 
  valley, 
  at 
  High 
  Falls, 
  there 
  rises 
  one 
  of 
  the 
  principal 
  anticlinals 
  

   of 
  the 
  Shawangunk 
  mountain, 
  which 
  soon 
  brings 
  up 
  Shawangunk 
  

   grit 
  in 
  the 
  low 
  ridge 
  on 
  which 
  the 
  village 
  is 
  built. 
  This 
  ridge 
  

   gradually 
  increases 
  in 
  width 
  and 
  altitude 
  southward, 
  and 
  near 
  

   the 
  line 
  of 
  the 
  third 
  section 
  on 
  plate 
  12 
  its 
  crest 
  is 
  nearly 
  as 
  high 
  

   as 
  the 
  ridge 
  eastward, 
  from 
  vhich 
  it 
  is 
  separated 
  by 
  the 
  synclinal 
  

   valley 
  of 
  the 
  Coxingkill. 
  

  

  South 
  from 
  Alligerville 
  the 
  mountain 
  widens 
  rapidly 
  as 
  flexure 
  

   after 
  flexure 
  brings 
  up 
  the 
  Shawangunk 
  grit 
  from 
  the 
  north- 
  

   westward. 
  The 
  western 
  ridges 
  rise 
  gradually 
  with 
  the 
  upward 
  

   pitch 
  of 
  the 
  axes 
  of 
  the 
  flexure 
  and 
  finally 
  become 
  the 
  highest 
  

   part 
  of 
  the 
  mountain 
  east 
  of 
  Ellenville. 
  Southwest 
  of 
  Lake 
  

   Mohonk 
  the 
  range 
  comprises 
  five 
  of 
  these 
  flexures, 
  together 
  with 
  

   various 
  small 
  undulations 
  of 
  the 
  beds, 
  and 
  there 
  is 
  a 
  creek 
  in
