  On 
  the 
  New 
  York 
  side 
  of 
  the 
  river 
  the 
  rocks 
  form 
  a 
  steep 
  cliff 
  

   200 
  feet 
  or 
  more 
  in 
  hight 
  at 
  a 
  place 
  known 
  as 
  the 
  Hawk's 
  nest. 
  

   The 
  dip 
  as 
  determined 
  from 
  the 
  canal 
  below 
  is 
  between 
  6° 
  and 
  7° 
  

   N, 
  10° 
  E. 
  No 
  red 
  rocks 
  were 
  seen 
  in 
  this 
  cliff 
  either 
  from 
  the 
  

   canal 
  or 
  the 
  Hawk's 
  nest 
  road. 
  On 
  the 
  hill 
  toward 
  Mongaup 
  is 
  

   a 
  thick 
  deposit 
  of 
  sand 
  and 
  the 
  older 
  rocks 
  are 
  well 
  covered 
  by 
  

   it 
  and 
  drift. 
  There 
  is 
  apparently 
  another 
  sand 
  hill 
  on 
  the 
  west- 
  

   ern 
  side 
  of 
  the 
  river 
  nearly 
  opposite 
  the 
  Hawk's 
  nest. 
  On 
  the 
  

   Pennsylvania 
  side 
  just 
  below 
  the 
  Pond 
  Eddy 
  station 
  is 
  an 
  ex- 
  

   posure 
  of 
  17 
  feet 
  of 
  red 
  shale. 
  This 
  is 
  probably 
  not 
  the 
  base 
  of 
  

   the 
  red 
  rocks 
  but 
  it 
  is 
  certain 
  that 
  the 
  base 
  is 
  several 
  miles 
  above 
  

   the 
  Erie 
  railroad 
  bridge 
  where 
  the 
  base 
  of 
  the 
  Catskill 
  formation 
  

   is 
  represented 
  as 
  crossing 
  the 
  river 
  on 
  the 
  Geologic 
  map 
  of 
  New 
  

   York 
  and 
  it 
  has 
  been 
  so 
  indicated 
  on 
  the 
  accompanying 
  map.
