This  coal  has  not  yet  been  mined,  and  though  of  good  thickness  will 
yield  but  small  areas  on  account  of  its  elevation. 
Upper  Hignite  coal. — This  coal  has  attracted  some  attention  in  Log 
Mountains  at  the  heads  of  Hignite  Creek,  Little  Clear  Creek,  and 
Bear  Branch  of  Big  Clear  Creek,  but  does  not  seem  to  be  generally 
workable,  unless  what  has  been  called  the  Lower  Hignite  coal  else- 
where may  in  places  be  the  Upper  Hignite.  It  lies  400  to  450  feet 
below  the  Red  Spring  coal,  in  which  space  six  or  more  coals  occur,  of 
which  one  is  workable  in  places.  This  coal  shows  the  following  sec- 
tion on  Hignite  Creek:

Lower  Hignite  coal. — This  coal  lies  10  to  20  feet  below  the  Upper 
Hignite  and  an  equal  distance  above  a  sandstone  which  makes  rather 
prominent  cliffs,  probably  more  prominent  than  those  made  by  any 
other  sandstone  above  the  Mingo  coal,  to  be  described  on  another  page. 
On  account  of  its  good  section  and  qualit}^  though  yielding  only 
comparatively  small  areas  because  of  its  elevated  position  in  the 
mountains,  this  bed  has  been  considered  one  of  the  best  in  the  region.

The  first  commercial  opening  on  this  coal  was  being  made  in  1903 
on  New  Cabin  Fork  of  Bennett  Fork. 
Klondike  coal.— This  coal  lies  300  to  400  feet  below  the  last-described
