The  coal  outcrops  in  the  northwest  end  of  a  small  anticline  which 
trends  southeastward  from  this  point,  running  beneath  the  alluvium 
of  the  Shoshone  River  valley  and  reappearing  in  the  bluffs  on  the 
south  side.  The  same  bed  is  exposed  in  the  cliffs  on  the  south  side 
of  Sage  Creek,  1  mile  southwest  of  Cowley  station.  The  coal  has  been 
traced  westward  along  these  bluffs  for  about  8  miles  to  sec.  3,  T.  56  N., 
R.  98  W.,  where  it  bends  sharply  across  the  axis  of  a  syncline  and 
then  runs  southeastward  along  the  east  side  of  the  Garland  anticline. 
On  the  west  side  of  the  Garland  anticline  the  coal  bed  has  been  traced 
northwestward  from  Shoshone  River  to  the  Bridger  field  in  Montana. 
In  the  bluffs  on  the  north  side  of  Shoshone  River,  in  the  NE.  |  sec.  6, 
T.  55  IN.,  R.  97  W.,  Eagle  coal  is  exposed  in  the  following  section:

Eight  miles  northwest  of  this  point  there  is  a  prospect  in  the  NW.  J 
sec.  4,  T.  56  N.,  R.  98  W.,  about  a  quarter  of  a  mile  east  of  the  Cody 
branch  of  the  Burlington  Railroad.  The  coal  here  is  about  20  inches 
thick.  The  Eagle  coal  bed  is  not  believed  to  exceed  this  thickness 
in  any  part  of  the  Garland  coal  field.  On  Polecat  Butte,  4  miles 
southwest  of  Frannie,  Wyo.,  this  coal  horizon  is  represented  by  black 
carbonaceous  shale  containing  a  few  worthless  streaks  of  coal.  Such 
is  its  character  from  this  point  northward  beyond  the  State  line. 
Goal  in  the  Glaggett  formation. — The  Claggett  formation  contains 
thin  beds  of  coal  at  many  places  in  the  Garland  field.  These  beds 
are  not  workable  at  any  of  the  exposures  examined  by  the  writer,  the 
greatest  thickness  being  only  1  foot  9  inches.  This  exposure  is  in 
the  SW.  \  sec.  5,  T.  55  N.,  R.  97  W.,  3  miles  below  the  Garland  wagon 
bridge,  on  the  south  bank  of  Shoshone  River.  The  section  here  is 
as  follows:
