  to 
  the 
  southeast 
  there 
  is 
  a 
  dip 
  varying 
  from 
  6° 
  to 
  9° 
  N, 
  80° 
  W. 
  

   The 
  increase 
  of 
  the 
  dip 
  is 
  apparent 
  as 
  one 
  goes 
  eastward 
  toward 
  

   the 
  folded 
  ridges 
  which 
  become 
  more 
  conspicuous 
  farther 
  south 
  

   in 
  Athens 
  and 
  Catskill 
  townships. 
  Southeastward 
  the 
  Hamilton 
  

   formation 
  is 
  found 
  at 
  the 
  summit 
  of 
  the 
  highway 
  where 
  it 
  crosses 
  

   the 
  northern 
  end 
  of 
  Ooleberg 
  hill. 
  

  

  On 
  the 
  hill 
  to 
  the 
  west 
  of 
  the 
  East 
  Branch 
  Potuck 
  and 
  about 
  

   one 
  mile 
  west 
  of 
  Urlton 
  are 
  green 
  and 
  red 
  shales. 
  The 
  outcrop 
  

   is 
  on 
  the 
  road 
  toward 
  Kesult 
  and 
  west 
  of 
  the 
  first 
  road 
  turning 
  

   north 
  on 
  the 
  western 
  side 
  of 
  the 
  West 
  Branch 
  Potuck. 
  The 
  

   shales 
  are 
  argillaceous 
  and 
  above 
  them 
  is 
  reddish 
  sandstone. 
  On 
  

   the 
  Geologic 
  map 
  of 
  New 
  York 
  the 
  base 
  of 
  the 
  Oneonta 
  formation 
  

   is 
  drawn 
  at 
  the 
  three 
  corners 
  west 
  of 
  Result, 
  two 
  and 
  one 
  fourth 
  

   miles 
  west 
  of 
  this 
  locality. 
  There 
  are 
  other 
  outcrops 
  of 
  the 
  red 
  

   rocks 
  along 
  this 
  highway 
  to 
  the 
  east 
  of 
  the 
  region 
  mapped 
  as 
  

   Oneonta, 
  and 
  on 
  the 
  hill 
  to 
  the 
  east 
  of 
  Result 
  is 
  a 
  massive 
  ledge 
  

   of 
  red 
  sandstone.

  Two 
  miles 
  south 
  of 
  Urlton 
  the 
  East 
  Branch 
  Potuck 
  

   and 
  West 
  Branch 
  Potuck 
  unite 
  forming 
  Potuck 
  creek. 
  One 
  fourth 
  

   mile 
  to 
  the 
  west 
  on 
  the 
  Gayhead 
  road 
  is 
  the 
  Baker 
  flagging 
  stone 
  

   quarry 
  where 
  a 
  ledge 
  10 
  feet 
  thick 
  has 
  been 
  opened. 
  It 
  is 
  a 
  blue 
  

   sandstone 
  making 
  fair 
  flagging 
  and 
  the 
  flags 
  contain 
  a 
  fair 
  num- 
  

   ber 
  of 
  specimens 
  of 
  Spirifer 
  granulosus 
  (Con.) 
  H.

   chia

   This 
  sandstone 
  ridge 
  is 
  evidently 
  in 
  the 
  Hamilton 
  formation 
  

   though 
  near 
  its 
  top, 
  for 
  at 
  the 
  four 
  corners 
  three 
  fourths 
  of 
  a 
  mile 
  

   to 
  the 
  west 
  are 
  red 
  argillaceous 
  shales 
  which 
  continue 
  to 
  the 
  

   west 
  along 
  the 
  Gayhead 
  road 
  across 
  the 
  northern 
  end 
  of 
  Indian 
  

   ridge. 
  

  

  To 
  the 
  east 
  of 
  the 
  Potuck 
  creek 
  it 
  is 
  very 
  rocky 
  and 
  rugged, 
  

   making 
  an 
  extremely 
  poor 
  farming 
  country. 
  The 
  rocks 
  of 
  

   Potuck 
  hill 
  and 
  the 
  smaller 
  ridges 
  to 
  the 
  west 
  on 
  the 
  eastern 
  side 
  

   of 
  the 
  creek 
  apparently 
  belong 
  in 
  the 
  Hamilton 
  formation, 
  which 
  

   in 
  this 
  region 
  is 
  composed 
  mainly 
  of 
  sandstones 
  and 
  coarse, 
  

   arenaceous 
  shales. 
  From 
  Urlton 
  the 
  top 
  of 
  the 
  formation 
  ap- 
  

   parently 
  follows 
  the 
  valley 
  of 
  the 
  East 
  Branch 
  Potuck 
  and
