The  higher  beds  are  covered  by  unconformable  Tertiary  shale.     The 
following  is  a  section  at  this  place,  where  the  strata  dip  60°  W.:

Locality  No.  4:  At  a  point  S.  50°  W.  of  Gallina  the  Mesaverde 
disappears  beneath  unconformable  Tertiary  and  granite  wash. 
Between  this  point  and  the  hogback,  3^  miles  N.  40°  E.  of  Cuba,  the 
formation  is  covered  except  for  a  small  outcrop  of  resistant  sandstone 
here  and  there.  Where  the  hogback  reappears  northeast  of  Cuba  the 
formations  from  Triassic  up  to  Puerco,  inclusive,  are  overturned  and 
dip  70°  E.  At  this  point  the  following  section  was  taken  in  the 
Mesaverde:

The  coal  bed  in  this  section  is  apparently  made  up  of  excellent  coal, 
so  far  as  physical  appearances  show.  This  is  the  bed  which  has  been 
locally  mined  at  Senorito,  6  miles  farther  south.
