DURANGO-GALLIIP    COAL    FIELD,    COLORADO-NEW    MEXICO.        247 
K  the  Talian  mine,  situated  on  Indian  land  4  miles  north  of  Pagosa  Junction,  on  the  Rio 
Krande,  Pagosa  and  Northern  Railroad.  At  this  mine  the  dip  of  the  rocks  is  26°,  and  a 
Section  of  the  coal  beds  exposed  is  as  follows:

I  The  coal  is  used  principally  for  steam  and  domestic  purposes. 
I  At  the  Archuleta  tunnel  (abandoned),  7  miles  northeast  of  Juanita,  the  coal  was  mined 
■ome  years  ago  and  used  in  drilling  for  oil  at  the  head  of  Montezuma  and  Coyote  creeks. 
iThe  coal  bed  consists  of  10+  feet  of  good  coal,  including  two  shale  partings  varying  from  1 
lo  2  inches  in  thickness.  The  floor  and  roof  are  shale,  and  the  dip  of  the  beds  is  to  the 
louthwest  at  the  angle  of  about  5°. 
MONERO    DISTRICT. 
The  Monero  district  extends  from  Navajo  River,  at  the  Colorado  line,  southward  along 
;he  Continental  Divide  to  Horse  Lake,  New  Mexico.  It  lies  in  the  plateau  proper  and  apart 
rom  the  foothills  of  the  San  Juan  Mountains,  from  which  it  is  separated  by  the  Chama 
/alley.  It  is  bounded  on  the  east  for  the  most  part  by  a  prominent  eastward-facing  escarp- 
nent  several  hundred  feet  high,  formed  by  the  upturned  edges  of  the  Mesaverde  sandstone, 
vhich  here  forms  the  Continental  Divide  and  is  locally  known  as  the  "rim  rock."  It  drains 
,o  the  west  by  way  of  Amargo  Arroyo  into  Navajo  River. 
In  this  district  the  coal  beds  of  the  Laramie  (?)  are  thin,  shaly,  and  unimportant,  but  the 
Mesaverde  formation  contains  two  main  beds  of  workable  thickness  and  of  about  the  same 
juality  as  the  Mesaverde  coal  in  the  Durango  district.  The  coal  contains  much  fossil  resin, 
which  accelerates  its  combustion  and  renders  it  desirable  for  domestic  use.  It  is  a  coking 
joal,  and  its  chemical  composition  is  shown  in  analyses  Nos.  12  and  13  in  the  table  on 
Dage  258. 
The  only  locality  at  which  mining  is  done  on  a  commercial  scale  is  Monero,  which  is  located 
ear  the  center  of  the  district,  on  the  Denver  and  Rio  Grande  Railroad.  At  this  place  the 
eneral  dip  of  the  rocks  is  about  4^°  W.,  but  this  is  far  from  regular,  as  the  beds  are  cut  by 
number  of  faults  which  disturb  their  dip  and  continuity. 
Three  mines  have  been  opened  at  Monero.  The  Kutz  mine  was  temporarily  shut  down 
t  the  time  it  was  visited,  but  considerable  coal  has  been  taken  from  it.  The  section  of  the 
oal  beds  exposed  in  this  mine  is  as  follows:

A  sample  was  taken  of  the  upper  bed  at  this  mine  for  chemical  analysis.  The  material 
for  the  sample  was  obtained  by  making  a  cut  across  the  face  of  the  coal  from  roof  to  floor, 
a  distance  of  3  feet  5  inches,  and  as  there  are  no  partings  in  the  coal  the  sample  contained 
everything  in  the  bed.  This  material  was  pulverized  and  quartered  down  at  the  mine 
until  a  quart  sample  was  obtained,  and  this  was  sealed  air-tight  in  a  galvanized  iron  can 
and  sent  to  the  laboratory  for  analysis.  The  result  is  shown  in  analysis  No.  12  in  the  table 
>npage  258.
