It  will  be  observed  that  in  this  section  there  are  fourteen  coal  beds 
that  are  not  of  workable  thickness,  and  only  one— the  3-foot  bed  just 
above  the  basal  sandstone — that  is  more  than  2  feet  thick.  The  coal 
of  this  bed  is  apparently  a  good  grade  of  subbituminous  a  coal. 
Locality  No.  2:  About  2 J  miles  northwest  of  Gallina  the  Mesaverde 
formation  shows  two  workable  beds  which  are  probably  identical  with 
some  of  the  thin  beds  farther  north.  The  lowest  coal  horizon  is 
covered  in  this  vicinity.  The  following  is  a  section  of  these  beds; 
the  strata  dip  45°  N.  45°  W.

Locality  No.  3:  South  of  Gallina  no  workable  coals  were  observed 
in  the  Mesaverde,  although  the  bed  occurring  elsewhere  immediately 
above  the  basal  sandstone  may  be  present  here.  This  coal  bed  is 
associated  with  over  100  feet  of  thin  sandstone  and  shale,  and  along 
the  steep  hogback  a  valley  is  formed  at  this  horizon;  as  a  result  the 
talus  from  the  protruding  basal  sandstone,  together  with  dwarf 
vegetation,  completely  covers  the  beds  in  this  vicinity.  The  two 
workable  beds  that  are  present  at  locality  No.  2,  northwest  of  Gallina, 
have  probably  thinned  very  much  or  disappeared. 
Inasmuch  as  there  are  several  thin  beds  in  the  upper  portion  which 
on  the  surface  show  a  considerable  quantity  of  loose  coal,  it  seems  well 
to  give  a  general  section  of  the  Mesaverde  coal  beds  in  this  locality. 
«  The  term  subbituminous  has  been  adopted  by  the  Geological  Survey  for  that  class  of  coal  com- 
monly known  as  "  black  lignite."
