  A 
  comparison 
  of 
  the 
  elevation 
  of 
  the 
  base 
  of 
  the 
  Oneonta 
  sand- 
  

   stone 
  in 
  the 
  Emmons 
  section 
  with 
  that 
  of 
  the 
  Ostdawa 
  affords 
  

   the 
  means 
  for 
  determining 
  the 
  amount 
  of 
  dip 
  a 
  mile 
  between 
  

   the 
  two 
  localities. 
  The 
  base 
  of 
  the 
  Oneonta 
  sandstone 
  in 
  the 
  

   Emmons 
  section 
  is 
  390 
  feet 
  above 
  railroad 
  level 
  and 
  in 
  the 
  Ots- 
  

   dawa 
  section 
  approximately 
  60 
  feet. 
  The 
  railroad 
  level 
  at 
  Otego 
  

   is 
  approximately 
  73 
  feet 
  lower 
  than 
  at 
  Emmons 
  which 
  makes 
  the 
  

   Oneonta 
  sandstone 
  approximately 
  403 
  feet 
  lower 
  in 
  the 
  Ostdawa 
  

   glen 
  than 
  in 
  the 
  Emmons 
  section. 
  The 
  two 
  stations 
  are 
  about 
  

   9.6 
  miles 
  apart 
  which 
  would 
  give 
  a 
  dip 
  of 
  42 
  feet 
  a 
  mile 
  to 
  the 
  

   southwest. 
  

  

  To 
  the 
  southwest 
  of 
  Otego 
  the 
  Oneonta 
  sandstone 
  soon 
  runs 
  

   down 
  to 
  the 
  level 
  of 
  the 
  highway 
  and 
  there 
  are 
  frequent 
  ex- 
  

   posures 
  of 
  red 
  shale 
  and 
  sandstone, 
  alternating 
  with 
  coarse 
  gray- 
  

   ish 
  sandstone 
  by 
  the 
  side 
  of 
  the 
  highway 
  between 
  Otego 
  and 
  

   Wells 
  Bridge 
  in 
  the 
  southeastern 
  corner 
  of 
  Unadilla 
  township. 
  

  

  On 
  the 
  Geologic 
  Map 
  of 
  Neiv 
  York 
  the 
  base 
  of 
  the 
  Oneonta 
  sand- 
  

   stone 
  is 
  represented 
  at 
  East 
  Unadilla 
  which, 
  is 
  probably 
  some 
  

   three 
  or 
  four 
  miles 
  too 
  far 
  to 
  the 
  southwest. 
  The 
  dip 
  would 
  

   indicate 
  that 
  the 
  base 
  of 
  the 
  Oneonta 
  sandstone 
  reaches 
  river 
  

   level 
  within 
  a 
  distance 
  of 
  less 
  than 
  two 
  miles 
  southwest 
  of 
  Otego. 
  

  

  Unadilla 
  

  

  This 
  is 
  the 
  southwestern 
  township 
  of 
  Otsego 
  county, 
  situated 
  

   to 
  the 
  west 
  of 
  Otego 
  and 
  bounded 
  respectively 
  on 
  the 
  south 
  and 
  

   west 
  by 
  the 
  Susquehanna 
  and 
  Unadilla 
  rivers 
  which 
  come 
  to- 
  

   gether 
  at 
  the 
  southwestern 
  corner 
  of 
  the 
  township. 
  The 
  greater 
  

   part 
  of 
  the 
  township 
  is 
  covered 
  by 
  the 
  Oneonta 
  formation, 
  the 
  

   red 
  and 
  gray 
  sandstones 
  being 
  well 
  exposed 
  along 
  a 
  number 
  of 
  

   the 
  streams. 
  In 
  the 
  Delaware 
  and 
  Hudson 
  railroad 
  cut 
  above 
  

   Unadilla 
  village 
  is 
  an 
  excellent 
  exposure 
  of 
  the 
  Oneonta 
  greenish 
  

   sandstone 
  and 
  red 
  shales. 
  The 
  high 
  ground 
  in 
  the 
  northeastern 
  

  

  part 
  of 
  /the 
  township 
  is 
  covered 
  by 
  the 
  Chemung 
  while 
  the 
  hill 
  

  

  « 
  

   at 
  the 
  southwestern 
  point 
  forming 
  the 
  divide 
  between 
  the 
  Una- 
  

   dilla 
  and 
  Susquehanna 
  rivers 
  is 
  capped 
  by 
  the 
  base 
  of 
  the 
  

   Chemung.
