  in 
  place 
  and 
  others 
  not. 
  There 
  are 
  layers 
  of 
  breccia 
  with 
  clay 
  

   pebbles 
  but 
  no 
  fossils 
  were 
  found. 
  In 
  C 
  4 
  there 
  are 
  red 
  shales 
  

   below, 
  then 
  coarse 
  grained 
  gray 
  sandstone* 
  which 
  is 
  reddish 
  

   above, 
  and 
  the 
  upper 
  45 
  feet 
  as 
  far 
  as 
  exposed 
  is 
  red 
  sandstone. 
  

   There 
  are 
  algoid 
  stems 
  in 
  the 
  coarse 
  red 
  shale 
  but 
  no 
  other 
  

   fossils 
  were 
  found. 
  The 
  upper 
  part 
  of 
  the 
  hill 
  (C 
  6 
  ) 
  is 
  apparently 
  

   all 
  red 
  argillaceous 
  shale, 
  some 
  of 
  which 
  is 
  of 
  bloeky 
  structure, 
  

   showing 
  on 
  the 
  main 
  Eoxbury 
  road 
  about 
  40 
  feet 
  below 
  the 
  

   summit 
  of 
  the 
  hill. 
  On 
  the 
  Geologic 
  map 
  of 
  New 
  York 
  the 
  Oneonta 
  

   sandstone 
  is 
  represented 
  along 
  the 
  lower 
  part 
  of 
  the 
  hill 
  while 
  

   above 
  this 
  and 
  reaching 
  its 
  summit 
  is 
  the 
  Chemung 
  formation. 
  

   As 
  is 
  seen 
  from 
  the 
  above 
  section 
  in 
  the 
  upper 
  270 
  feet 
  of 
  the 
  

   hill 
  red 
  shales 
  and 
  sandstones 
  apparently 
  predominate. 
  

  

  Through 
  the 
  pass 
  between 
  Eoxbury 
  and 
  Grand 
  Gorge 
  the 
  

   coarse 
  greenish 
  gray 
  sandstones, 
  and 
  red 
  shales 
  and 
  sandstones 
  

   of 
  the 
  Oneonta 
  formation 
  are 
  well 
  shown. 
  

  

  On 
  the 
  hill 
  about 
  one 
  mile 
  north 
  of 
  Grand 
  Gorge 
  (formerly 
  

   Moresville) 
  on 
  the
