  The 
  highway 
  was 
  followed 
  up 
  Keyser's 
  creek 
  from 
  

   Houston 
  Corners 
  nearly 
  to 
  the 
  southeastern 
  corner 
  of 
  Fulton 
  

   township; 
  but 
  without 
  satisfactory 
  results 
  on 
  account 
  of 
  the 
  

   mantle 
  of 
  drift 
  which 
  conceals 
  most 
  of 
  the 
  rocks. 
  On 
  the 
  creek 
  

   banks 
  some 
  110 
  feet 
  above 
  zone 
  A 
  2 
  at 
  Houston 
  Corners 
  are 
  bluish 
  

   shales 
  and 
  sandstones 
  (X 
  1 
  ) 
  which 
  are 
  probably 
  in 
  the 
  Hamilton 
  

   formation 
  although 
  no 
  fossils 
  were 
  seen. 
  From 
  the 
  creek 
  to 
  

   the 
  highway, 
  approximately 
  185 
  feet, 
  the 
  rocks 
  are 
  completely 
  

   concealed; 
  but 
  on 
  the 
  hill 
  northeast 
  of 
  the 
  road 
  there 
  are 
  two 
  

   ledges 
  of 
  coarse 
  greenish 
  gray 
  sandstone, 
  one 
  at 
  420 
  feet 
  above 
  

   the 
  creek 
  and 
  the 
  other 
  near 
  the 
  top 
  of 
  the 
  hill 
  at 
  780 
  feet 
  above 
  

   the 
  creek. 
  Loose 
  on 
  the 
  hillside 
  between 
  the 
  two 
  outcrops 
  of 
  

   the 
  greenish 
  sandstone 
  are 
  numerous 
  large 
  blocks 
  of 
  the 
  red 
  

   sandstone 
  which 
  evidently 
  occurs 
  somewhere 
  in 
  that 
  part 
  of 
  the 
  

   hill. 
  The 
  stratigraphic 
  position 
  of 
  these 
  red 
  sandstone 
  blocks 
  

   agrees 
  in 
  a 
  general 
  way 
  with 
  its 
  supposed 
  horizon 
  near 
  the 
  top
