  Location. 
  

  

  The 
  Butler 
  salt 
  dome 
  1 
  or 
  West 
  Point 
  dome, 
  as 
  it 
  is 
  

   usually 
  called 
  from 
  the 
  name 
  of 
  a 
  former 
  landing 
  on 
  the 
  

   Trinity 
  River 
  north 
  of 
  the 
  dome, 
  is 
  in 
  Freestone 
  County, 
  

   Texas, 
  2% 
  miles 
  east 
  of 
  Butler, 
  30 
  miles 
  east 
  of 
  Teague, 
  

   and 
  15 
  miles 
  west 
  of 
  Palestine. 
  It 
  is 
  about 
  3 
  miles 
  from 
  

   Bonner's 
  Ferry 
  on 
  the 
  Trinity 
  River 
  and 
  is 
  8 
  miles 
  in 
  a 
  

   straight 
  line 
  from 
  the 
  Palestine 
  salt 
  dome.' 
  It 
  is 
  on 
  a 
  

   line 
  with 
  the 
  Palestine 
  (Salt 
  Works), 
  Keechi, 
  and 
  Brooks 
  

   salt 
  domes 
  and 
  this 
  line 
  may 
  also 
  be 
  drawn 
  through 
  the 
  

   Steen 
  salt 
  dome 
  at 
  the 
  north 
  end 
  of 
  Smith 
  County. 
  This 
  

   ,is 
  one 
  of 
  the 
  lines 
  of 
  weakness 
  emphasized 
  by 
  Harris 
  2 
  

   along 
  which 
  the 
  salt 
  domes 
  have 
  risen. 
  The 
  only 
  other 
  

   interior 
  salt 
  dome

  in 
  east 
  Texas, 
  unless 
  the 
  Brenham 
  

   dome 
  be 
  so 
  classed, 
  is 
  the 
  Grand 
  Saline 
  dome 
  in 
  Van 
  

   Zandt 
  County.
