  State 
  Museum. 
  

  

  The 
  white 
  conglomeratic 
  beds 
  are 
  separated 
  from 
  the 
  underlying 
  

   members 
  by 
  thin 
  streaks 
  of 
  red 
  shale, 
  but 
  this 
  may 
  be 
  only 
  a 
  local 
  

   feature. 
  On 
  Slide 
  mountain 
  the 
  beds 
  consist 
  of 
  gray, 
  buff 
  and 
  

   greenish-buff, 
  coarse 
  sandstone, 
  with 
  scattered 
  pebbles 
  and 
  streaks 
  

   of 
  pebbles, 
  which 
  attain 
  a 
  thickness 
  of 
  350 
  feet 
  in 
  the 
  higher 
  

   summit 
  of 
  the 
  mountain. 
  There 
  is 
  a 
  small 
  cap 
  of 
  the 
  formation 
  

   on 
  Mount 
  Cornell, 
  also 
  on 
  "Wittemburgh 
  and 
  apparently 
  also 
  on 
  

   Table 
  mountain, 
  Panther 
  mountain 
  and 
  Peak 
  o-Moose. 
  It 
  was 
  

   thought 
  that 
  the 
  western 
  dip 
  should 
  carry 
  this 
  formation 
  down 
  to 
  

   Double 
  Top 
  and 
  Graham 
  mountains, 
  but 
  these 
  exhibit 
  only 
  the 
  

   red 
  conglomeratic 
  beds 
  at 
  their 
  summits. 
  It 
  is, 
  however, 
  possible 
  

   that 
  the 
  white 
  beds 
  are 
  only 
  a 
  local 
  phase 
  of 
  the 
  eastern 
  extension 
  

   of 
  the 
  red 
  deposits. 
  

  

  In 
  the 
  northern 
  Catskills, 
  in 
  Woodstock 
  township, 
  particularly 
  

   on 
  Overlook 
  mountain 
  the 
  Upper 
  Flag 
  series 
  is 
  extensively 
  exposed. 
  

   Ascending 
  from 
  Woodstock 
  village 
  to 
  Overlook 
  mountain 
  there 
  

   are 
  alternations 
  of 
  red 
  shales 
  and 
  gray 
  or 
  greenish-gray 
  flags 
  all 
  

   the 
  way 
  to 
  the 
  top. 
  At 
  an 
  elevation 
  of 
  about 
  300 
  feet 
  above 
  

   Woodstock 
  there 
  is 
  a 
  particularly 
  heavy 
  bed 
  of 
  red 
  shales 
  which 
  

   has 
  a 
  thickness 
  of 
  forty 
  feet, 
  and 
  there 
  are 
  other 
  thick 
  beds 
  near 
  

   the 
  summit. 
  The 
  summit 
  is 
  a 
  cap 
  of 
  hard, 
  gray, 
  flaggy 
  sandstone 
  

   twenty-five 
  feet 
  thick, 
  lying 
  on 
  twenty-five 
  feet 
  of 
  red 
  shales. 
  

   Along 
  the 
  road 
  which 
  passes 
  just 
  northward 
  there 
  are 
  some 
  

   alternations 
  of 
  underlying 
  gray 
  sandstones 
  with 
  thin 
  streaks 
  of 
  red 
  

   shales. 
  At 
  one 
  point 
  north 
  of 
  the 
  hotel 
  about 
  two 
  hundred 
  feet 
  

   below 
  the 
  summit, 
  there 
  are 
  thin 
  streaks 
  of 
  quartz 
  conglomerate, 
  

   of 
  quartz 
  and 
  quartzitic 
  pebbles 
  in 
  a 
  gray 
  sandstone 
  matrix 
  and 
  

   again 
  at 
  a 
  point 
  500 
  feet 
  below 
  this 
  horizon 
  several 
  thin 
  con- 
  

   glomeratic 
  streaks 
  are 
  exposed 
  on 
  the 
  southwest 
  slope. 
  

  

  Southeastern 
  Townships. 
  

  

  The 
  region 
  extending 
  from 
  the 
  eastern 
  face 
  of 
  the 
  Shawan- 
  

   gunk 
  mountains 
  to 
  the 
  Hudson 
  river 
  is 
  occupied 
  by 
  the 
  Hudson 
  

   river 
  formation. 
  The 
  greater 
  part 
  of 
  the 
  area 
  is 
  underlaid 
  by 
  

   slates 
  and 
  shales, 
  but 
  to 
  the 
  eastward 
  in 
  the 
  high 
  ridges 
  extend- 
  

   ing 
  from 
  near 
  Marlborough 
  to 
  Rondout 
  there 
  are 
  sandstones 
  and 
  

   grits 
  occupying 
  a 
  considerable 
  area. 
  Much 
  of 
  the 
  slate 
  region 
  

   is 
  gently 
  undulating 
  with 
  many 
  low 
  ridges 
  of 
  drift, 
  and 
  it 
  is 
  

   traversed 
  by 
  the 
  wide 
  valleys 
  of 
  the 
  Wallkill 
  and 
  Swartkill,
