BURNING. 
Much  of  the  coal  of  this  field  is  burned  along  the  outcrop.  The 
amount  of  burning  is  relatively  small  in  the  Mesaverde  and  about 
equally  prominent  in  each  of  the  other  coal-bearing  formations.  In 
some  places  the  effects  on  the  adjacent  rocks  can  be  seen  several  feet 
from  the  actual  seat  of  burning;  in  others,  rocks  a  very  short  distance 
away  are  not  affected.  A  quarter  of  a  mile  southeast  of  Muddy 
Bridge  a  small  caved  drift  in  the  fjaramie  formation  exposes  about 
18  inches  of  highly  bituminous  shale  underlain  by  a  few  feel  of  dirty 
coal.     Near  by  the  bituminous  shale  has  been  burned  out,  causing
