  All 
  the 
  clays 
  of 
  Wyoming 
  that 
  have 
  any 
  commercial 
  importance 
  

   occur 
  in 
  the 
  sedimentary 
  beds 
  of 
  the 
  Jurassic 
  and 
  Cretaceous 
  for- 
  

   mations, 
  but 
  are 
  also 
  found 
  to 
  some 
  extent 
  in 
  the 
  Tertiary. 
  The 
  

   formations 
  containing 
  these 
  clays 
  are 
  found 
  flanking 
  nearly 
  all 
  the 
  

   naountain 
  ranges 
  in 
  the 
  state. 
  But 
  with 
  the 
  exception 
  of 
  their 
  

   being 
  used 
  for 
  the 
  manufacture 
  of 
  common 
  brick 
  in 
  a 
  few 
  locali- 
  

   ties, 
  very 
  little 
  development 
  has 
  occurred. 
  All 
  the 
  fire 
  clay 
  prod- 
  

   ucts 
  now 
  used 
  in 
  Wyoming 
  are 
  manufactured 
  in 
  Colorado 
  ; 
  pressed 
  

   brick 
  are 
  also 
  shipped 
  into 
  the 
  state 
  from 
  various 
  points. 
  

  

  The 
  loess 
  is 
  utilized 
  at 
  a 
  number 
  of 
  places 
  in 
  Wyoming.
