SAGE,   WYO. 
The  phosphate  beds  are  seen  again  near  Sage,  Wyo.,  a  station  on 
the  Oregon  Short  Line  Railroad,  about  24  miles  northeast  of  WbodJ 
ruff.  The  outcrop  extends  in  a  southerly  direction  a  few  miles  to 
the  southwest  of  the  railroad.  Sonic  shipments  have  recently  been 
made  from  Sage  to  the  Pacific  coasl  and  work  is  now  going  on. 
COKEVILLE,   WYO. 
The  Sublette  Range  extends  along  the  eastern  side  of  the  Bear 
River  valley  in  this  region.     A   hold   escarpmenl    of  Carboniferous 
strata,  which  has  been  cut  through  by  Smiths  Fork,  faces  the  valley 
opposite  Cokeville,  Wyo.  The  section  as  exposed  on  the  north  side 
of  Smiths  Fork  is  shown  in  fig.  Is. 
The  quartzite  beds  are  in  vertical  position  with  a  tendency  to 
overturn  to  the  west.     In  the  lower  pail  of  the  upper  Carboniferous 
ction  J  miles  northeasl  of  Cokeville,  Wyo.,  <>n  north  side  of  Smiths  Fork.    I,  Weber 
quartzite;  2,  upper  "Coal  Measures"  limestone;  3,  phosphate  hods;   1,  "  Permo-Carboniferous"  lime- 
es  and  sandstones;  5,  (  i  Liver    limestones  and  sandstones;  X,  fossil  localities. 
series  the  beds  dip  65  E.  for  some  distance,  beyond  which  they  stand 
nearly  vertical.  A  fault  occurs  by  which  the  Bear  River  (Creta- 
ceous) is  broughl  againsl  the  "  Permo-Carboniferous,"  cutting  out 
the  Triassic  and  Jurassic,  which  according  to  Veatcha  have  together 
an  average  thickness  of  5,500  feel  in  the  region  to  the  east.  The 
strike  of  the  beds  follows  the  general  trend  of  the  range. 
Ahout  2  miles  northeast  of  Cokeville,  on  the  north  side  of  Smiths 
Fork,  the  surface  covering  has  been  removed  from  t  he  phosphate  beds, 
which  are  exposed  for  a  distance  of  100  feel  up  the  slope  of  the  ridge, 
dipping  65°  E.  The  uppermost  layer  of  the  series  is  a  6-fool  bed  of 
phosphate  and  below  this,  separated  by  3  feet  of  brown  shale  and 
hard,  blue  limestone,  is  another  bed  1  to  5  feet  thick. 
Two  tunnels  have  been  cul  into  the  main  bed,  one  about  35  feet 
the  other  about  50  feet  in  length.  A  square  box  chute  with  steel 
bottom  has  been  built  along  the  outcrop,  extending  down  to  storage 
bins  near  the  base  of  the  ridge.  The  rock  is  bard  and  requires  con- 
siderable   blasting.     The    material    is    shoveled    into    wheelbarrows.
