﻿CLASSIFICATION,

  OF 
  HAMILTON 
  AND 
  CHEMUNG 
  SERIES

  To 
  the 
  east 
  of 
  the 
  hill 
  described 
  above, 
  is 
  the 
  former 
  hamlet 
  of 
  

   Morseville 
  in 
  the 
  northern 
  part 
  of 
  Jefferson 
  township 
  on 
  the 
  

   highway 
  from 
  Summit 
  to 
  Jefferson. 
  On 
  the 
  hill 
  east 
  of 
  Morse- 
  

   ville 
  is 
  coarse 
  grained, 
  massive 
  sandstone 
  very 
  similar 
  in 
  general 
  

   appearance 
  to 
  the 
  heavy 
  sandstone 
  seen 
  at 
  the 
  base 
  of 
  the 
  One- 
  

   onta 
  sandstone 
  along 
  the 
  valleys 
  of 
  the 
  Susquehanna 
  river 
  and 
  

   Schenevus 
  creek. 
  Farther 
  south 
  on 
  the 
  hill 
  about 
  two 
  and 
  one 
  

   third 
  miles 
  west 
  of 
  north 
  of 
  Jefferson 
  village 
  and 
  some 
  225 
  feet 
  

   higher 
  are 
  massive 
  deposits 
  of 
  this 
  coarse 
  grained 
  sandstone 
  

   (XXVII 
  A 
  1 
  ). 
  As 
  far 
  as 
  the 
  color 
  and 
  lithologic 
  appearance 
  of 
  this 
  

   stone 
  are 
  concerned 
  it 
  would 
  be 
  difficult 
  to 
  distinguish 
  it 
  from 
  

   typical 
  exposures 
  of 
  the 
  Oneonta 
  sandstone 
  in 
  Otsego 
  and 
  Dela- 
  

   ware 
  counties. 
  These 
  ledges, 
  however, 
  are 
  not 
  considered 
  to 
  be 
  

   stratigraphically 
  as 
  high 
  as 
  the 
  base 
  of 
  the 
  Oneonta 
  sandstone 
  in 
  

   the 
  Susquehanna 
  valley; 
  but 
  it 
  is 
  thought 
  that 
  similar 
  lithologic 
  

   conditions 
  appear 
  at 
  a 
  lower 
  horizon 
  in 
  rocks 
  which 
  are 
  synchro- 
  

   nous 
  with 
  the 
  upper 
  part 
  of 
  the 
  Ithaca 
  formation 
  of 
  Otsego 
  

   co. 
  It 
  is 
  believed 
  the 
  record 
  of 
  the 
  observations 
  across 
  Schoharie 
  

   co. 
  will 
  show 
  that 
  the 
  conditions 
  under 
  which 
  the 
  Oneonta 
  sand- 
  

   stone 
  was 
  deposited 
  in 
  Chenango, 
  Otsego 
  and 
  Delaware 
  counties 
  

   occurred 
  earlier 
  and 
  earlier 
  as 
  the 
  formation 
  is 
  followed 
  to 
  the 
  

   eastward 
  till 
  the 
  Ithaca 
  formation 
  finally 
  merged 
  into 
  the 
  

   Oneonta. 
  The 
  change 
  seems 
  to 
  have 
  been 
  about 
  the 
  same 
  as 
  the 
  

   one 
  described 
  in 
  Delaware 
  county 
  where 
  the 
  Chemung 
  formation 
  

   merges 
  into 
  the 
  Catskill.

  . 
  About 
  one 
  and 
  one 
  fourth 
  miles 
  north 
  of 
  Morseville 
  

   and 
  two 
  and 
  one 
  third 
  miles 
  southwest 
  of 
  Summit 
  village 
  in 
  the 
  

   southern 
  part 
  of 
  Summit 
  township 
  is 
  a 
  conspicuous 
  mound 
  or 
  

   circular 
  hill. 
  Its 
  top 
  is 
  approximately 
  170 
  feet 
  higher 
  than 
  the 
  

   four 
  corners 
  at 
  Summit 
  and 
  it 
  is 
  a 
  conspicuous 
  landmark 
  when 
  

   seen 
  from 
  the 
  high 
  land 
  to 
  the 
  east 
  of 
  Summit 
  as 
  well 
  as 
  from 
  

   other 
  localities 
  in 
  Summit 
  and 
  Jefferson 
  townships. 
  The 
  rocks 
  

   are 
  pretty 
  well 
  covered 
  on 
  the 
  mound, 
  but 
  there 
  are 
  some 
  ex- 
  

   posuies 
  of 
  shales 
  and 
  shaly 
  sandstones; 
  while 
  the 
  slope 
  is 
  quite 
  

   well 
  covered 
  with 
  loose 
  pieces 
  that 
  evidently 
  came 
  out 
  of 
  the 
  hill. 
  

   Bpirifer 
  mesastrialis 
  Hall 
  with 
  a 
  few 
  other 
  species 
  are 
  found 
  and
