  A 
  Geologic 
  Section 
  from 
  40 
  Miles 
  West 
  of 
  

   St.

  County 
  to 
  Jackson 
  County, 
  Missouri;

  Sections 
  of 
  the 
  geology 
  of 
  St. 
  Louis 
  County 
  1 
  and 
  Jack- 
  

   son 
  County, 
  2 
  Missouri 
  have 
  been 
  published 
  recently 
  and 
  

   it 
  will 
  help 
  those 
  not 
  familiar 
  with 
  the 
  geology 
  of 
  the 
  

   state 
  to 
  have 
  a 
  section 
  connecting 
  these 
  eastern 
  and 
  west- 
  

   ern 
  counties. 
  The 
  sections 
  shown 
  in 
  the 
  accompanying 
  

   figures 
  were 
  prepared 
  from 
  data 
  obtained 
  as 
  described 
  in 
  

   the 
  following 
  paragraphs. 
  

  

  The 
  writer 
  has 
  mapped 
  in 
  detail 
  the 
  geology 
  through 
  

   which 
  the 
  section 
  passes 
  from 
  eastern 
  Warren 
  County 
  to 
  

   eastern 
  Moniteau 
  County, 
  a 
  distance 
  of 
  about 
  90 
  miles, 
  

   and 
  has 
  examined 
  large 
  numbers 
  of 
  outcrops 
  and 
  made 
  

   less 
  detailed 
  maps 
  on 
  the 
  west 
  end 
  of 
  the 
  section 
  through 
  

   Moniteau, 
  Cooper, 
  and 
  Pettis 
  counties. 
  Complete 
  map- 
  

   ping 
  in 
  these 
  counties 
  will 
  doubtless 
  bring 
  to 
  light 
  details 
  

   not 
  shown 
  in 
  the 
  section. 
  Between 
  Charette 
  Creek 
  in 
  

   "Warren 
  County 
  and 
  the 
  west 
  line 
  of 
  St. 
  Louis 
  County, 
  a 
  

   distance 
  of 
  about 
  20 
  miles, 
  no 
  mapping 
  or 
  sectioning 
  has 
  

   been 
  done. 
  

  

  The 
  extreme 
  western 
  end 
  of 
  the 
  section, 
  which 
  involves 
  

   Pennsylvanian 
  strata, 
  is 
  taken 
  mainly 
  from 
  the 
  reports 
  

   of 
  Marbut 
  3 
  and 
  Hinds 
  4 
  and 
  is 
  included 
  merely 
  to 
  connect 
  

   the 
  western 
  end, 
  involving 
  Missis 
  sippian 
  and 
  older 
  

   strata, 
  with 
  the 
  Jackson 
  County 
  section. 
  The 
  writer 
  has 
  

   made 
  no 
  investigations 
  along 
  the 
  line 
  of 
  the 
  section 
  west 
  

   of 
  Sedalia, 
  in 
  Pettis 
  County. 
  

  

  Maps 
  showing 
  details 
  of 
  Devonian 
  distribution 
  will 
  

   appear 
  in 
  a 
  bulletin 
  of 
  the 
  Missouri 
  State 
  Bureau 
  of 
  

   Geology 
  and 
  Mines, 
  and 
  the 
  stratigraphy 
  of 
  the 
  Syla- 
  

   more 
  and 
  related 
  formations 
  will 
  be 
  treated 
  at 
  length 
  in 
  

   a 
  report 
  soon 
  to 
  be 
  published. 
  

  

  The 
  strata 
  shown 
  are 
  nearly 
  horizontal 
  along 
  the 
  line 
  

   of 
  the 
  section 
  if 
  minor 
  folds 
  are 
  neglected. 
  The 
  top 
  of 
  

   the 
  Jefferson 
  City 
  dolomite 
  lies 
  at 
  an 
  elevation 
  of 
  about 
  

   650 
  feet 
  in 
  eastern 
  Warren 
  County
