PUNXSUTAWNEY    AND    GLEN    CAMPBELL    COAL    FIELDS,   PA.        27  < 
THE  COALS. 
PUNXSUTAWNEY    BASIN. 
j  For  convenience  of  discussion  the  different  fields  may  be  given  in  order,  beginning  at 
Punxsutawney.  In  this  basin  practically  all  mining  at  present  is  on  the  "D"  coal.  The 
;fE"  coal,  which  overlies  it  at  an  interval  of  from  38  to  43  feet,  reaches  a  thickness  of  3 
Jeet  4  inches  over  a  considerable  area  northeast  of  Punxsutawney,  but  appears  to  run 
but  to  the  east  and  south.  Future  mining  on  this  bed  will  depend  on  the  extent  to  which 
(he  work  on  the  "D"  coal  has  disturbed  it.  The  coals  below  the  "D"  are  below  drainage 
through  most  of  this  basin,  and  little  is  known  of  their  thickness  and  character,  but  it  is 
Claimed  that  they  are  not  workable.  The  "D"  bed  ranges  from  4  to  6  feet  in  thickness 
Running  up  to  10  or  11  feet  locally.  Around  Adrian,  Walston,  and  Elk  Run  it  will  average 
about  5  feet  6  inches.  Toward  Big  Run  and  Eleanora  it  is  thinner,  ranging  from  4  to  4J 
Leet,  and  toward  Winslow  it  thins  to  less  than  4  feet.  For  a  distance  south  of  Punxsutaw- 
rey  all  the  coals  appear  to  be  absent  or  thin.  Around  Rossiter  one  of  these  coals  comes  in 
ivith  a  thickness  of  from  3  feet  8  inches  to  4  feet  6  inches,  thinning  to  the  northwest  and 
thickening  to  the  southeast.  This  has  generally  been  called  the  "E"  coal.  There  is,  how- 
aver,  at  an  interval  of  40  feet  above  it  a  trace  of  coal  underlain  by  clay,  and  that  again  by 
limestone,  which  come  directly  below  what  is  considered  to  be  the  Mahoning  sandstone. 
We  have,  therefore,  considered  the  Rossiter  coal  as  the  "D"  coal. 
The  "D"  coal  through  the  Punxsutawney  basin  is  usually  free  from  partings,  but  in  the 
vicinity  of  Big  Run  and  Winslow  shows  1  or  2  inches  of  bony  coal  10  to  12  inches  from  the 
bottom.  Over  the  coal  are  often  from  8  to  9  inches  of  bony  coal.  The  roof  is  shale,  generally 
showing  a  thickness  of  12  to  14  feet  or  more,  but  in  places  it  is  thin  and  overlain  by  a 
sandstone  that  comes  down  close  to  or  lies  directly  upon  the  coal.  Where  the  shale  of 
the  roof  is  thin  it  is  inclined  to  be  tender,  and  in  places  this  prevents  the  use  of  machines 
in  mining.     The  floor  shows  from  2  to  4  feet  of  clay. 
GLEN    CAMPBELL   OR    CUSH    CREEK    FIELD. 
The  field  work  in  the  region  about  Glen  Campbell  has  not  yet  been  completed,  so  that 
many  questions  of  correllation  still  remain  to  be  settled.  The  general  facts,  however,  may 
be  stated  at  the  present  time. 
Around  Glen  Campbell  and  to  the  northeast  and  northwest  the  "E,"  "D,"  and  "C"  coals 
are  all  being  worked  commercially.  Just  under  the  Mahoning  sandstone,  which  north  of  Glen 
Campbell  is  very  massive,  occurs  the  "E"  coal,  which  is  about  4  feet  thick.  North  and 
west  of  Smithport  it  is  often  broken  up  with  bony  partings.  From  18  to  30  feet  lower 
occurs  the  "D"  coal.  Locally  this  shows  as  two  large  benches,  each  broken  with  partings, 
giving  a  total  thickness  of  16  to  19  feet.  These  benches  will  yield  from  3  to  6  feet  of  work- 
able coal.  It  has  been  suggested  that  the  "D"  and  "C"  coals  have  come  close  together 
at  this  point.  Most  of  the  openings  around  Glen  Campbell  on  the  "D"  coal  show  from  6 
to  18  inches  of  bone,  or  bone  and  coal,  with  a  lower  bench  of  from  3  to  3J  feet  of  good  coal, 
having  1  inch  of  bone  a  little  less  than  halfway  from  the  bottom.  From  30  to  40  feet 
below  the  "D"  coal  is  the  "C"  coal,  which  is  being  worked  about  Glen  Campbell  and 
which  there  shows  a  thickness  ranging  from  4  feet  6  inches  to  6  feet,  with  from  1  to  2  inches 
of  soft  bony  coal  8  to  12  inches  from  the  top. 
Drillings  north  of  Glen  Campbell  indicate  that  both  the  "C"  and  "B"  coals  are  present 
in  workable  thickness.  The  aC"  coal  in  one  drilling  is  reported  as  9  feet  thick,  but  an 
adjacent  drilling  showed  only  3  feet  of  coal  and  rock  at  the  same  horizon.  The  "B"  coal 
appears  to  have  a  thickness  of  from  3  to  over  4  feet;  still  below  that  are  a  number  of  coals, 
usually  not  of  workable  thickness.  On  the  whole,  the  region  close  about  Glen  Camp- 
bell seems  to  yield  a  large  number  of  workable  coals,  but  these  coals  are  often  broken  up 
by  partings  so  as  not  to  be  economically  minable.
