The  uppermost  coal  bed  in  the  above  section  becomes  locally 
thicker  and  may  be  workable  in  places  in  T.  6  N.,  R.  47  E.  A 
section  follows:

Southward  from  this  locality  the  coal  outcrops  at  many  places, 
but  is  everywhere  divided  by  thin  clay  partings  which  render  it 
unworkable. 
One  of  the  beds  is  locally  workable  in  the  divides  between  Mill, 
Squaw,  and  Pumpkin  creeks,  in  T.  6  N.,  R.  48  E.,  where  it  contains 
3  feet  4  inches  of  workable  coal  near  the  northwest  corner  of  sec.  25 
and  4  feet  near  the  east  quarter  corner  of  sec.  12.  These  meas- 
urements are  exceptional,  however,  as  many  other  exposures  of  the 
bed  in  the  same  vicinity  show  numerous  clay  partings  in  the  coal. 
Some  of  the  beds  are  probably  also  workable  in  a  few  places  in  T.  5  N., 
R.  48  E.,  but  the  presence  of  characteristic  thin  clay  partings  renders 
most  of  the  coal  unfit  for  mining. 
Many  attempts  to  work  these  coals  have  been  made  in  Tps.  7  and 
8  N.,  R.  48  E.,  but  all  the  openings  have  been  abandoned  on  account 
of  the  impurities  in  the  coal.  The  following  section  of  the  beds  at  this 
horizon  was  measured  near  Signal  Butte,  in  sec.  6,  T.  7  N.,  R.  48  E.:
