claimed  by  prospectors,  two  faults  instead  of  one  are  required,  and  it  will  be  necessary  to  show 
that  a  part  of  the  high  country  between  Huntington  Canyon  and  Pleasant  Valley  is  faulted 
upward  a  thousand  feet  or  more.  Certain  thick  and  distinct  sandstone  beds,  alwa  \  s  ass<  xialcd 
with  the  lower  coals,  were  not  noted  in  the  vicinity  of  the  prospects  west  of  Clear  ( !reek.  Rock 
exposures  are  less  frequent,  however,  toward  the  mountain  tops  than  in  the  lower  parts  of  the 
canyons. 
Miller  Canyon. — Two  coal  beds  have  been  exposed  by  prospect  near  the  center  of  the  N.  ^ 
sec.  32,  T.  15S.,R.  8  E.  The  lower  bed,  10  feet  thick,  is  apparently  25  feet  above  the 
horizon  of  the  lowest  coal  in  the  Book  Cliffs  section.  The  second  bed  is  4  feet  thick  and  is 
separated  from  the  first  by  5  to  6  feet  of  shale.  The  upper  coal  is  overlain  by  massive  sand- 
stone. Near  the  center  of  the  west  side  of  sec.  20  several  beds  of  coal  occur  near  the  base  of 
the  coal-bearing  rocks  in  natural  exposures.  Some  of  these  give  evidence  of  workable  thick- 
ness, though  the  coal  is  disintegrated  at  the  surface. 
Cedar  Canyon. — The  basal  coal  in  the  Book  Cliffs  section  has  been  worked  occasionally  for 
a  number  of  years  in  the  north  side  of  Cedar  Canyon,  in  the  SW.  \  sec.  9,  T.  16  S.,  R.  8  E. 
The  coal  is  20  feet  thick  and  is  separated  locally  into  three  benches  by  variable  thin  bony  and 
shaly  partings.  The  lower  bench,  11  feet  thick,  is  massive  and  clean.  The  middle  bench  is 
5  feet  thick  and  the  upper  bench  4  feet.  The  coal  lies  on  massive  sandstone  and  is  succeeded 
by  beds  of  thin  and  shaly  sandstone.  A  tunnel  300  to  400  feet  long  has  been  driven  toward 
the  north  on  the  lower  coal,  a  short  distance  west  of  the  present  working,  in  the  SE.  \  sec.  8. 
The  coal  in  this  mine  varies  in  thickness  from  16  to  20  feet,  and  it  is  reported  by  one  of  the 
operators  that  no  shaly  partings  were  found.  The  operations  in  Cedar  Creek  are  conducted  by 
Messrs.  Howard  &  Sons,  of  Huntington,  and  they  are  known  as  the  Howard  mine.  A  coal 
bed  is  partially  exposed  in  the  north  side  of  the  canyon  400  feet  stratigraphically  above  the 
Howard  mine.  Several  feet  of  disintegrated  coal  are  shown,  but  the  full  thickness  of  the  bed 
was  not  determined. 
Huntington  Canyon. — Systematic  prospecting  has  been  done  in  Huntington  Canyon 
through  Tps.  16  and  17  S.,  R.  7  E.  The  prospectors  confined  their  attention  to  the  coals 
in  the  lower  part  of  the  coal-bearing  section,  and  it  is  reported  by  the  State  coal-mine  inspec- 
tor that  more  than  1,000  openings  have  been  made  on  these  beds. 
Twelve  or  more  prospects  have  been  made  exposing  workable  coal  beds  in  Bear  Gulch,  in 
sees.  24  and  25,  T.  16  S.,  R.  7  E.  Two  of  the  lower  coals  are  exposed  on  the  west  side  of 
the  gulch,  in  the  northwest  corner  of  sec.  25.  The  section  of  coals  and  associated  rocks  is  as 
follows : 
Section  in  Bear  Gulch,  NW.  \  sec.  25,  T.  16  S.,  R.  7  K. 
1.  Heavy  sandstone.  Feet. 
2.  Shale 1.5 
3.  Massive  coal 10 
4.  Shale  and  sandstone,  alternating  beds;  the  sandstone  at  the  top  makes  the 
floor  of  the  upper  coal 40 
5.  Sandstone 17 
6.  Shaly  roof 1 
7.  Massive  coal 12 
8.  Massive  sandstone;  base  of  lower  coal. 
Five  other  beds  of-workable  coals,  aggregating  a  thickness  of  48  feet,  are  reported  inde- 
pendently by  two  reputable  prospectors  to  have  been  opened  at  several  places  in  300  feet  of 
strata  on  the  east  side  of  the  gulch,  in  the  S.  \  sec.  24.  Several  prospects  have  been  made  on 
some  of  these  coals  also  in  the  west  half  of  the  same  section. 
A  massive  coal  bed,  13  feet  4  inches  thick,  situated  near  the  base  of  the  coal-bearing  section, 
is  mined  for  local  use  in  Deer  Gulch,  in  the  NW.  \  sec.  11,  T.  17  S.,  R.  7  E.  A  coal  bed  3 
feet  thick  has  been  prospected  on  the  west  side  of  the  gulch,  near  the  middle  of  the  east  side  of 
sec.  10.     This  coal  is  about  175  feet  above  the  coal  in  the  mine. 
A  coal  bed  partially  burned,  exposed  in  Meeting  House  Gulch,  in  the  NE.  \  SE.  \  sec.  34, 
T.  16  S.,  R.  7  E.,  shows  3  feet  of  coal.     Two  beds  of  coal  are  opened  in  three  prospects  near
