COAL.   BETWEEN    GALLINA  AND   KATON    SPRING,    N.    MEX.         351 
Westward  from  this  locality  the  coal  boundaries  were  traced  beyond 
the  limit  of  the  area  mapped,  but  no  sections  were  obtained.  The  beds 
are  much  burned  and  covered  along  the  head  drainage  of  Rio  Chaco 
north  of  Raton  Spring.  In  the  immediate  vicinity  of  Raton  the 
geologic  mapping  connects  with  that  of  Shalera  in  1906. 
DEVELOPMENT  AND  TRANSPORTATION. 
The  only  coal  mining  in  the  Gallina-Raton  Spring  field  has  been 
done  in  connection  with  the  operations  of  local  copper  companies  at 
Copper  City,  in  the  Gallina-Cuba  area.  A  mine  was  worked  here  for 
a  brief  time  on  the  upper  coal  bed  of  the  Mesaverde,  but  was  discon- 
tinued with  the  closing  of  the  smelters.  The  coal  gave  good  satis- 
faction and  is  evidently  a  high-grade  coal  of  the  subbituminous  class. 
The  coals  in  the  Raton  Spring  area  have  not  been  prospected  and 
little  can  be  said  regarding  their  quality.  They  resist  weathering 
fairly  well,  however,  and  from  all  appearances  are  similar  to  the  best 
Laramie  beds  throughout  the  San  Juan  region.  The  topography  of 
the  region  is  such  that  practicable  railroad  routes  may  be  found  to 
any  part  of  the  field.  The  nearest  railroad  points  at  present  are  on 
the  Denver  and  Rio  Grande,  45  miles  north  of  Gallina;  the  Farming- 
ton  branch  of  the  same  line,  55  miles  N.  35°  W.  from  Raton  Spring; 
and  the  Atchison,  Topeka  and  Santa  Fe,  48  miles  S.  35°  W.  from  Raton 
Spring.
