  red 
  sandstones 
  apparently 
  become 
  more 
  abundant 
  and 
  continue 
  

   so 
  nearly 
  to 
  the 
  top 
  of 
  the 
  range 
  1025 
  feet 
  above 
  the 
  Manorkill. 
  

   No 
  fossils 
  were 
  found 
  in 
  the 
  rocks 
  of 
  this 
  section. 
  From 
  the 
  top 
  

   of 
  this 
  hill 
  there 
  is 
  a 
  fine 
  view 
  to 
  the 
  northeast 
  of 
  the 
  eastern 
  

   " 
  Border 
  Chain 
  " 
  of 
  the 
  Catskills 
  from 
  Sutton 
  hill 
  pass 
  to 
  Leonard 
  

   hill 
  ; 
  to 
  the 
  west 
  are 
  the 
  high 
  hills 
  of 
  the 
  Schoharie 
  river 
  toward 
  

   Summit 
  and 
  on 
  the 
  south 
  and 
  southeast 
  is 
  the 
  Blackhead 
  range. 
  

   On 
  the 
  Geologic 
  map 
  of 
  New 
  York 
  the 
  elevated 
  part 
  of 
  this 
  range 
  

   to 
  the 
  east 
  of 
  the 
  highway 
  is 
  mapped 
  as 
  in 
  the 
  Chemung. 
  Its 
  base 
  

   is 
  represented 
  as 
  considerably 
  above 
  the 
  lever 
  of 
  the 
  road 
  while 
  

   the 
  rocks 
  on 
  the 
  western 
  side 
  of 
  the 
  road 
  to 
  the 
  Schoharie 
  valley 
  

   and 
  below 
  along 
  the 
  Manorkill 
  valley 
  are 
  mapped 
  as 
  Oneonta. 
  

   Apparently 
  the 
  rocks 
  mapped 
  as 
  Chemung 
  are 
  those 
  shown 
  in 
  

   tne 
  upper 
  part 
  of 
  section 
  LXI 
  A, 
  which 
  are 
  composed 
  to 
  a 
  consider- 
  

   able 
  extent 
  of 
  reddish 
  sandstones, 
  perhaps 
  one 
  half 
  of 
  them 
  

   having 
  this 
  color. 
  The 
  lithologic 
  appearance 
  of 
  the 
  rocks 
  is 
  not 
  

   that 
  of 
  the 
  Chemung 
  and 
  with 
  no 
  fossils 
  to 
  assist 
  in 
  determining 
  

   it 
  is 
  difficult 
  to 
  see 
  why 
  they 
  should 
  be 
  called 
  Chemung. 
  On 
  the 
  

   Geologic 
  map 
  of 
  New 
  York 
  the 
  Chemung 
  formation 
  capped 
  by 
  the 
  

   Catskill 
  is 
  represented 
  as 
  following 
  the 
  northeast 
  "Border 
  Chain" 
  

   of 
  the 
  Catskills 
  from 
  Sutton 
  hill 
  to 
  near 
  the 
  northern 
  line 
  of 
  the 
  

   township. 
  In 
  this 
  range 
  to 
  the 
  northeast 
  of 
  Conesville 
  is 
  a 
  con- 
  

   spicuous 
  hill 
  known 
  as 
  High 
  Knob 
  which 
  is, 
  according 
  to 
  Guyot, 
  

   2654 
  feet 
  A. 
  T. 
  Its 
  western 
  slope 
  is 
  pretty 
  well 
  covered 
  by 
  soil 
  

   but 
  there 
  are 
  several 
  prominent 
  ledges 
  which 
  are 
  indicated 
  on 
  the 
  

   following 
  section. 
  Some 
  835 
  feet 
  higher 
  than 
  Conesville 
  near 
  the 
  

   foot 
  of 
  High 
  Knob 
  there 
  is 
  a 
  coarse 
  gray, 
  irregularly 
  bedded 
  sand- 
  

   stone. 
  240 
  feet 
  higher 
  there 
  is 
  another 
  heavy 
  ledge 
  of 
  the 
  coarse 
  

   gray 
  sandstone 
  with 
  some 
  red 
  sandstone 
  below 
  and 
  reddish 
  sand- 
  

   stone 
  at 
  its 
  top. 
  Near 
  the 
  top 
  of 
  the 
  hill, 
  145 
  feet 
  higher, 
  is 
  a 
  

   heavy 
  ledge 
  of 
  red 
  sandstone 
  below 
  which 
  is 
  red 
  shale; 
  while 
  the 
  

   top 
  of 
  the 
  ledge 
  changes 
  into 
  a 
  grayish 
  sandstone.
