Locality  No.  15:  A  section  was  made  in  the  southeastern  part  of 
sec.  33  of  the  same  township  and  shows  about  an  equal  quantity  of 
coal,  although  the  relations  of  one  bed  to  another  are  somewhat 
different. 
Locality  No.  16:  In  sec.  13,  T.  14  N.,  R.  9  W.,  there  are  three  beds 
in  the  escarpment  of  the  Mesaverde  worthy  of  mention.  They  are 
shown  in  the  following  section :

Locality  No.  17 :  In  T.  14  N.,  R.  8  W.,  the  outcrop  of  the  Mesaverde 
formation  makes  a  decided  northward  swing;  from  the  east  side  of 
sec.  34  it  encircles  a  wide  area  covering  several  square  miles  to  the 
north  and  returns  to  the  west  side  of  sec.  35  in  the  same  township. 
From  this  point  the  boundary  passes  westward,  showing  as  a  mesa 
in  sec.  9,  and  thence  southward  to  the  point  of  disappearance  beneath 
the  lava  surrounding  Mount*  Taylor. 
In  the  central  part  of  sec.  27,  T.  14  N.,  R.  8  W.,  a  coal  bed  4  feet 
2  inches  thick  was  observed  in  the  Mesaverde  formation.  The  bed  is 
about  20  feet  below  a  massive  sandstone,  60  to  100  feet  thick,  which 
caps  the  escarpment  at  that  place.
