Soldier  Canyon.- — Coal  has  been  mined  for  local  use  and  prospected  in  a  number  of  plac  g 
in  the  central  part  of  the  coal  series,  in- the  NE.  \  sec.  18,  T.  13  S.,  R.  12  E.  The  co  1 
worked  is  2  feet  7  inches  thick.  A  lower  coal  is  exposed  in  the  base  of  the  gulch  tributai  if 
to  Soldier  Canyon  in  the  NE.  J  sec.  13,  T.  13  S.,  R.  11  E.  This  natural  exposure  shov  3 
\\  feet  of  coal,  but  both  the  upper  and  lower  parts  are  concealed. 
Coal  Canyon. — Six  beds  of  coal  are  exposed  in  Coal  Canyon  in  the  E.  \  NW.  \  sec.  li 
T.  13  S.,  R.  11  E.     Four  of  these,  aggregating  22  feet,  are  thick  enough  to  work.     Thre  | 
occur  in  natural  exposures  and  two  have  been  mined.     The  coal  in  the  lower  mine  is  8  fet«o 
6  inches  thick  and  its  quality  is  indicated  by  analysis  No.  5  of  the  table  above.     It  occui  J 
between  massive  beds  of  sandstone,  each  40  to  -45  feet  thick.     The  coal  in  t ho  other  min<  I 
l.V>  feel   higher  in  the  section,  is  5  feet  thick  and  its  quality  is  shown  by  analysis  No.  ( 
There  is  an  intermediate  bed.  5  feet  4  inches  thick,  but  it  contains  a  thin  parting  of  l>on 
coal       The  lowest   bed.  3  feet -\  hick,  is  200  feet  below  the  lower  mine. 
Deadman  Canyon.  —A  coal  bed  6  feel  LO  inches  thick  has  been  prospected  in  the  SE. 
S\V.  ',  sec.  7.  T.  13  S.,  R.ll  E.  It  is  estimated  to  be  the  same  as  the  lowest  bed  mine 
in  Coal  Canyon.  A'  parting  of  shale  occurs  lii  inches  below  the  top.  Otherwise  thecJ 
appears  to  be  equal  to  the  corresponding  bed  mined  in  Coal  Canyon. 
Cordingly  Canyon.  A  coal  bed  I  feet  3  inches  thick  has  been  opened  in  the  east  fork  c 
Cordingly  Canyon,  in  the  NW.  I  sec.  1  I,  T.  13  S.,  \{.  10  E.  The  coal  has  a  shale  roc 
and  a  massive  sandstone 'floor.  It  has  a  bright  luster  and  is  clean,  but  fractures  easill 
and  a  considerable  quantity  of  slack  is  produced  in  mining.  This  coal  is  apparently  a 
the  base  of  the  coal-bearing  series.  A  coal  bed  11  feet  thick  occurs  L25  feet  higher  in  tb 
section,  between  a  massive  sandstone  60  feet  thick  below  and  another  sandstone  6  to  1 ! 
feet  thick  above.  A  thin  and  variable  parting  of  gnarly  sandy  shale  occurs  1  feet  belov 
the  top  of  the  coal.  The  coal  is  massive  and  lustrous,  but  breaks  readily  into  blocks  in 
mining,  in  a  similar  manner  to  the  lower  bed.  A  short  tunnel  or  drift  has  been  run  on  thi; 
coal  in  the  SE.  1  SW.  |  sec.  11. 
Bollinger  mine.  The  basal  coal  of  the  series  is  mined  in  the  west  fork  of  Cordingly  Call 
yon,  in  the  SE.  \  SW.  |  sec.  10,  T.  13  S.,  K.  L0  E.  The  coal  is  20  feet  thick,  massive,  an< 
moderately  hard.  It  mines  for  the  most  part  in  large  irregular  blocks.  Sandstone  occursn 
in  contact  both  above  and  below.  This  coal  is  mined  and  transported  by  wagon  foi 
domestic  use  in  the  town  of  Price.  Large  rooms  are  excavated  and  wagons  are  driver 
into  the  face  of  the  working  to  be  loaded. 
Wadi  i>n>xj>ii!x.  Three  coal  beds  are  exposed  in  the  prospects  of  Wade  and  Law  ley 
m  the  SW  |  \\V.  j  ...  Hi.  T.  13  S.,  R.  K)  E.  These  coals  occur  in  the  lower  100  feet  1 
the  coal-bearing  series.  The  lowest  coal  is  the  same  as  that  in  the  Ballinger  mine.  It  is 
20  feet  thick  and  massive.  It  rests  directly  on  a  solid  sandstone  and  has  a  .shaly  sand- 
stone roof.  The  second  coal,  !0  to  50  feet  above,  is  similar  in  structure  and  appearance 
to  the  first.  It  k  8  feet  6  inches  thick  and  lies  in  contact  with  the  sandstone  above  and 
below.  Of  the  third  coal  only  the  lower  1  .">  feet  are  exposed.  The  excavation  has  not 
penetrated  the  weathered  coal  in  the  upper  part,  where  tire  top  of  the  bed  is  concealed. 
A   thin   shaly  parting  occurs  2'    feet    above   the   base  of  this  coal.      The  lower  coal   in   this 
section  is  exposed  in  three  openings  in  the  west  fork  of  Bull  Canyon,  near  the  south  side 
9,  T.  13  S.,  R.  10  E. 
Panther  Canyon.  Two  prospects  have  been  driven  on  the  coal  at  the  base  of  the  series  in 
the  NW.  |  NW.  |  sec.  8,  T.  13  S.,  R.  10  E.  The  coal  has  been  burned  near'the  surface  in 
this  vicinity  and  the  shaHow  excavation*.-;  revealed  only  a  part  of  the  coal. 
Castlegate  mine. — One  of  the  coals  near  the  base  of  the  coal-bearing  series  is  mined  at 
Castlegate.  The  coal  is  worked  in  a  series  of  slopes  driven  on  the  rise  of  the  bed  toward 
the  south.  At  the  entrance  to  the  tenth  rise  in  the  northern  part  of  the  mined  area  the 
coal  is  a  little  more  than  4  feet  thick.  At  the  face  of  the  coal  in  the  first  rise  in  the  south- 
western part  of  the  mine  the  thickness  is  6  feet .  while  in  the  southeastern  part  it  is  10  feet . 
At  intermediate  points  it  varies  between  these  extremes.  The  coal  is  usually  massive  and 
clean.     The  floor  is  a  solid  sandstone  and  lies  in  low  rolls  or  undulations,  being  so  uneven
