DESCRIPTIONS   OF   THE    COAL   BEDS. 
morse  Canyon. — A  coal  bed  is  exposed  in  sec.  4,  T.  16  S.,  R.  14  E.,  near  the  base  of  tha 
Oil-bearing  series.  The  bed  is  14  feet  11  inches  thick  and  is  being  opened  for  develop- 
But.  The  coal  is  clean  and  massive.  The  floor  is  a  massive  sandstone.  The  roof  of 
Jdstone  and  shale  4  feet  thick  is  succeeded  by  2  feet  of  coal.  The  same  bed  was  reported 
ne  of  equal  thickness  at  prospects  in  sees.  3  and  9  of  the  same  township. 
qtunnyside  coals. — Two  coal  beds  are  mined  by  the  Utah  Fuel  Company  at  Sunnyside, 
Jr  the  mouth  of  Whitmore  Canyon,  in  sec.  32,  T.  14  S.,  R.  14  E.,  and  sec.  5,  T.  15  S., 
I|jl4  E.  These  coal  beds  are  near  the  base  of  the  coal-bearing  series.  The  lower  coal 
■ges  from  5  feet  3  inches  to  6  feet  5  inches  in  thickness,  while  the  upper  bed,  30  feet 
»ve,  averages  about  5  feet  10  inches.  Between  the  two  beds  are  30  feet  of  shale,  sand- 
Jhe,  and  thin  coal.  The  lower  Sunnyside  coal  contains  a  few  thin  and  locally  bony  lentils, 
■luster  is  rather  dull  and  it  is  classed  by  the  miner  as  "dead"  coal.  The  upper  bed  is 
in  and  bright.  It  yields  considerable  gas  on  mining  and  is  referred  to  as  a  "live"  coal. 
Ip  mines  are  in  operation  here.  Both  beds  are  worked  from  No.  1  mine,  while  No.  2 
le  is  confined  to  the  lower.  All  of  the  coal  is  run  to  a  single  tipple  and  is  crushed  and  the 
afire  product  coked,  the  larger  part  in  the  coking  plant  at  Sunnyside,  the  remainder 
bjpg  taken  to  the  ovens  at  Castlegate. 
■[he  composition  of  the  upper  coal  (No.  2  of  the  table)  is  almost  identical  with  the  Horse 
[lyon  coal  (No.  1).  The  analysis  of  the  crushed  product  from  all  the  Sunnyside  mines 
?IWs  a  slightly  higher  percentage  of  ash  and  lower  proportions  of  volatile  matter  and 
Eld  carbon.  The  ratios  between  the  volatile  matter  and  fixed  carbon,  however,  as  indi- 
ftd  in  the  two  analyses,  are  essentially  the  same. 
Vear  Canyon. — A  traverse  of  the  Book  Cliffs  scarp  across  T.  14  S.,  R.  13  E.,  which  has 
J  been  subdivided  into  sections,  locates  the  coal  prospects  of  Bear  Canyon  in  the  N.  \ 
>e  10.  Two  prospect  pits  have  been  dug  in  the  east  fork  of  the  canyon,  on  the  coal  at 
tfi  base  of  the  series.  The  bed  has  been  partially  burned  near  the  outcrop  and  only  \\ 
e  of  coal  is  exposed  in  the  excavation. 
ttock  Canyon.— A  coal  bed  5  feet  10  inches  thick  is  exposed  by  prospect  in  the  SE.  \ 
Mi  \  sec.  32,  T.  13  S.,  R.  13  E.  This  coal  is  near  the  same  horizon  as  the  Sunnyside 
J ,  being  probably  below  the  lower  bed  at  that  place. 
Vace  Canyon. — Prospecting  has  been  done  in  the  NW.  \  NW.  J  sec.  30,  T.  13  S.,  R.  13  E., 
ivilre  the  coal  has  been  burned  near  the  surface.  A  tunnel  has  been  driven  50  feet  on 
■burned  bed,  reaching  the  edge  of  the  fresh  coal.  Five  feet  of  fresh  coal  is  exposed  in 
iKther  prospect,  where  the  upper  part  was  concealed.  These  coals  are  in  the  lower  part 
Dthe  coal-bearing  series. 
dugout  Canyon. — The  lowest  coal  bed  in  this  series  has  been  mined  by  tunnel  in  the  SE. 
\  ;W.  \  sec.  23,  T.-13  S.,  R.  12  E.  The  bed  is  9  feet  6  inches  thick  and  contains  a  thin 
bj«y  seam  18  inches  below  the  top.  The  coal  is  otherwise  massive  and  clean.  Analysis 
l^'4  above  shows  the  coal  to  be  the  equal  of  any  other  that  has  been  tested  in  the  Book 
Oils  field.  Its  content  of  ash,  including  the  bony  parting,  is  the  lowest.  About  100  feet 
timer  in  the  section  is  a  second  bed  showing  5  feet  of  coal  in  a  shallow  prospect.  The 
assure  is  at  the  forks  of  the  canyon,  near  the  center  of  the  NW.  \  sec.  23.  This  coal  is 
ipirently  of  good  grade,  except  a  thin  parting  near  the  top.  A  third  double  bed  con- 
t&ing  4  feet  of  coal  occurs  200  feet  above  the  first,  in  a  shallow  prospect  in  the  north 
m  of  the  canyon.  The  parting  of  shale  is  2  feet.  One  bench  of  what  appears  to  be  the 
Jffle  coal  is  exposed  in  the  SE.  {  sec.  23,  also  in  the  SW.  \  SW.  \  sec.  15.  The  showing 
s  to  2\  feet  thick. 
winy  Canyon. — A  bed  of  coal  5  feet  4  inches  thick  has  been  opened  in  the  NE.  \  NW.  \ 
se*i21,  T.  13  S.,  R.  12  E.  There  is  a  thin  parting  in  the  coal  4  inches  below  the  top. 
Oterwise  the  coal  is  massive.  This  bed  is  in  the  lower  part  of  the  coal-bearing  series 
in  is  believed  to  be  50  feet  above  the  horizon  of  the  lowest  seam.
