GRAND   MESA   COAL   FIELD,    COLORADO.  319 
coal  at  Somerset,  on  the  North  Fork  of  the  Gunnison.  At  no  point 
within  the  field  does  the  coal  crop  out  more  than  15  miles  from  a  rail- 
road in  operation.  However,  much  of  the  coal  can  not  now  be 
reached  by  wagon.  No  roads  and  but  few  trails  cross  the  outcrop 
between  Palisades  and  the  Kuhnley  mine  (No.  18,  PL  XXI),  a  dis- 
tance of  more  than  25  miles.  East  of  the  Kuhnley  mine  wagon  roads 
have  been  built  to  the  coal  in  many  places,  but  on  the  North  Fork 
there  is  no  wagon  road  east  of  Bowie.
