  For 
  50 
  feet 
  the 
  hillside 
  is 
  covered 
  when 
  another 
  outcrop 
  of 
  

   coarser 
  and 
  more 
  arenaceous 
  shales 
  (C 
  3 
  ) 
  is 
  reached 
  which 
  also 
  con- 
  

   tains 
  abundant 
  Hamilton 
  fossils. 
  The 
  shales 
  are 
  capped 
  by 
  very 
  

   thin 
  bedded, 
  even 
  sandstones 
  and 
  the 
  zone 
  is 
  clearly 
  in 
  the 
  Ham- 
  

   ilton:

  On 
  the 
  hillside 
  55 
  feet 
  above 
  C 
  3 
  , 
  or 
  approximately 
  595 
  feet 
  

   higher 
  than 
  West 
  Fulton, 
  are 
  thin, 
  bluish 
  gray 
  sandstones 
  (C 
  4 
  ) 
  

   in 
  which 
  a 
  few 
  fossils 
  occur. 
  This 
  ledge 
  is 
  about 
  on 
  a 
  level 
  with 
  

   the 
  small 
  cemetery 
  on 
  the 
  north 
  side 
  of 
  the 
  road, 
  and 
  is 
  appar- 
  

   ently 
  in 
  the 
  Hamilton 
  formation. 
  40 
  feet 
  higher 
  is 
  a 
  ledge 
  of 
  

   thin 
  bedded, 
  bluish 
  gray 
  sandstone 
  five 
  feet 
  in 
  thickness. 
  A 
  lit- 
  

   tle 
  below 
  this 
  stratum 
  are 
  loose 
  fossils 
  which 
  seem 
  to 
  have 
  come 
  

   from 
  this 
  outcrop 
  and 
  apparently 
  show 
  its 
  Hamilton 
  age. 
  At 
  

   the 
  edge 
  of 
  the 
  woods 
  on 
  the 
  south 
  side 
  of 
  the 
  road 
  are 
  ledges 
  

   of 
  rather 
  coarse 
  grained, 
  thin 
  bedded, 
  grayish 
  sandstone 
  (C 
  5 
  ). 
  

   There 
  are 
  from 
  15 
  to 
  20 
  feet 
  of 
  these 
  sandstones 
  exposed, 
  which 
  

   apparently 
  occur 
  on 
  the 
  north 
  side 
  of 
  the 
  road 
  at 
  a 
  little 
  higher 
  

   elevation. 
  No 
  fossils 
  were 
  found 
  except 
  plant 
  stems; 
  but 
  there 
  

   are 
  numerous 
  clay 
  pebbles 
  in 
  some 
  of 
  the 
  layers. 
  This 
  zone 
  is 
  

   probably 
  near 
  the 
  dividing 
  line 
  between 
  the 
  Hamilton 
  and 
  Sher- 
  

   burne 
  formations 
  and 
  it 
  is 
  a 
  matter 
  of 
  some 
  uncertainty 
  to 
  which 
  

   formation 
  it 
  should 
  be 
  referred. 
  On 
  the 
  highway 
  50 
  feet 
  higher 
  

   or 
  825 
  feet 
  above 
  West 
  Fulton 
  are 
  bluish 
  to 
  greenish 
  ar- 
  

   gillaceous 
  shales 
  (C 
  6 
  ) 
  and 
  bluish 
  gray 
  flagging 
  stone. 
  No 
  fossils 
  

   were 
  found 
  and 
  in 
  lithological 
  characters 
  these 
  rocks 
  closely 
  

   resemble 
  those 
  of 
  the 
  Sherburne 
  formation 
  to 
  which 
  they 
  are 
  

   referred. 
  Just 
  south 
  of 
  the 
  turn 
  on 
  the 
  first 
  road 
  turning 
  south 
  

   toward 
  Eminence 
  are 
  thin 
  bedded, 
  bluish 
  gray, 
  flagging 
  stones 
  

   (C 
  7 
  ). 
  below 
  which 
  are 
  smooth, 
  bluish, 
  argillaceous 
  shales 
  weather- 
  

   ing 
  to 
  an 
  olive 
  tint 
  and 
  containing 
  some 
  concretionary 
  nodules. 
  

   These 
  shales 
  are 
  about 
  45 
  feet 
  above 
  those 
  of 
  C 
  6 
  . 
  

  

  On 
  the 
  highway 
  one 
  and 
  one 
  fourth 
  miles 
  east 
  of 
  Summit, 
  in 
  

   the 
  eastern 
  part 
  of 
  Summit 
  township, 
  on 
  the 
  divide, 
  is 
  a 
  layer 
  

   of 
  rather 
  irregular 
  sandstone 
  (C 
  8 
  ) 
  which 
  contains 
  a 
  few 
  fossils.
