This  coal  lies  between  two  massive  sandstones  and  at  an  elevation  of 
about  2,000  feet  above  sea  level.  If  widely  workable  it  would  there- 
fore yield  areas  of  fair  extent  all  over  this  district. 
KeUioka  coal. — About  200  feet  lower,  or  250  feet  above  the  Harlan 
coal,  occurs  the  Kellioka  coal,  usually  a  thick  coal,  but  generally  so 
badly  broken  up  with  partings  as  to  be  doubtfully  workable.  A  series 
of  sections  scattered  over  this  part  of  the  field  will  show  its  variability.
