SHERIDAN    COAL   FIELD,    WYOMING.  143 
Two  coal  beds  were  noted  in  the  valley  of  Hanging  Woman  Creek 
in  Montana,  about  12  miles  north  of  the  Wyoming  line.  J.  B.  Ken- 
drick  has  a  small  mine  in  sec.  2,  T.  8  S.,  R.  43  E.,  on  a  coal  bed  11 
feet  3  inches  thick,  with  an  overlying  bench  2  feet  thick.  This  bed 
is  near  the  stratigraphic  position  of  the  Dietz  coals,  and  the  physical 
character  and  fuel  value  of  the  coals  are  similar.  A  short  drift  had 
been  made  on  7  feet  3  inches  of  coal  in  the  lower  part  of  the  bed. 
Another  bed  nearly  300  feet  lower  in  the  rocks  occurs  in  the  bluffs 
of  Hanging  Woman  Creek,  near  the  north  line  of  T.  8  S.,  R.  43  E., 
Montana.  Fifteen  feet  of  coal  is  exposed  from  the  creek  bed  upward. 
The  upper  half  of  the  bed  seems  to  be  a  fair  quality,  but  the  lower 
part  contains  partings  of  bony  shale. 
A  coal  bed  at  about  the  same  horizon  is  exposed  in  the  bluffs  of 
Powder  River  in  sec.  21,  T.  57  N.,  R.  76  W.     Its  section  is  as  follows:

This  coal  is  exposed  beneath  an  overhanging  bluff  and  a  small 
quantity  of  coal  has  been  removed  from  the  lower  bench. 
Another  coal  *bed  of  considerable  thickness  and  areal  extent  has 
been  burned  in  the  bluffs  of  Powder  River,  150  feet  above  the  coal 
last  described.  Similar  indications  of  burned  coal  occur  along  Hang- 
ing Woman  Creek  above  the  Kendrick  coal  from  the  Wyoming  line 
northward. 
COAL    BEDS    ABOVE    TONGUE    RIVER    GROUP. 
Several  coal  beds  of  probable  commercial  value  were  noted  at  a 
number  of  places  between  the  Tongue  River  and  Ulm  coal  groups. 
The  coal  beds  are  usually  separated  into  several  benches  by  shale  or 
bands  of  bony  coal.  Most  of  these  beds  occur  high  in  the  rock  sec- 
tion and  nearer  the  Ulm  coals,  which  lie  above  them,  than  the  Tongue 
River  coals,  which  lie  below.  The  following  are  sections  of  coal  beds 
that  are  known  only  at  the  localities  specified:
