Coal  beds  occur  also  at  higher  horizons,  believed  to  be  in  the 
Laramie  formation.  A  section  of  one  of  these  upper  beds  which 
outcrops  in  the  SW.  \  sec.  25,  T.  52  N.,  R.  94  W.,  is  given  below.

In  sec.  6,  T.  53  N.,  R.  94  W.,  the  coal  is  only  6  inches  thick.  In 
sec.  8  it  is  18  inches  thick.  A  good  idea  of  the  character  of  the  upper 
coal  beds  may  be  obtained  from  the  following  section,  made  250  feet 
southwest  of  the  north  quarter  corner  of  sec.  16,  T.  53  N.,  R.  94  W. :
