COAL   OF   BRIDGER    FIELD,    MONTANA.  191 
About  500  feet  north  of  the  northwest  corner  of  sec.  6,  T.  6  S.,  K  23 
E.,  a  fault  cuts  the  outcrop  of  the  coal  bed  and  produces  an  offset  of 
nearly  2  miles.  The  trend  of  this  fault  is  N.  52°  E.,  and  the  down- 
throw is  to  the  northwest.  On  the  south  side  of  the  fault  the  coal  is 
exposed  in  several  places,  but  owing  to  the  drag  of  the  fault  a  good 
section  could  not  be  obtained.  At  one  place  21  inches  of  coal  was 
noted  and  at  another  31  inches. 
The  nearest  opening  north  of  the  fault  line  is  the  McCarthy  mine 
No.  1.  It  is  located  in  the  SE.  \  SW.  \  sec.  19,  T.  5  S.,  R.  23  E., 
Montana,  principal  meridian.  At  one  time  as  many  as  twenty  men 
were  employed  here,  but  now  the  mine  is  shut  down,  as  it  can  not  com- 
pete with  the  McCarthy  mine  No.  2  and  the  Gebo  mine,  where  the  bed 
is  thicker  and  nearer  the  railroad.  Owing  to  caving  of  the  mine,  only 
3  feet  of  coal  was  visible. 
In  a  prospect  hole  in  the  SW.  \  NE.  \  sec.  19,  T.  5  S.,  R.  23  E.,  1^ 
miles  southwest  of  Fromberg,  a  section  of  part  of  the  coal  bed  is  as

The  strike  of  the  bed  is  N.  25°  W.  and  the  dip  is  about  6   SW. 
The  McCarthy  mine  No.  2,  also  known  as  the  Carbon  mine,  owned 
and  operated  by  the  Alba  Coal  Company,  of  Fromberg,  is  located  in 
the  SE.J  SW.£  sec.  18,  T.  5  S.,  K.  23  lv  Twenty-five  men  are  em- 
ployed at  this  mine,  and  the  coal  is  hauled  in  wagons  to  the  railroad 
at  Fromberg.     The  coal  bed,  which  dips  5°  \\\,  is  worked  from  two
