  These 
  are 
  found 
  in 
  the 
  wetter 
  parts 
  of 
  the 
  valleys, 
  where 
  the 
  

   drainage 
  is 
  rather 
  poor. 
  They 
  contain 
  many 
  of 
  the 
  species 
  found 
  

   in 
  the 
  preceding 
  formation 
  but 
  also 
  many 
  belonging 
  to 
  the 
  Sedge 
  

   Bog. 
  The 
  most 
  important 
  woods 
  belonging 
  to 
  the 
  formation 
  are 
  

   the 
  Rocky 
  Mountain 
  alder, 
  Alnus 
  tenuifoUa, 
  the 
  western 
  black 
  

   birch, 
  Behda 
  Jontinalis, 
  and 
  several 
  species 
  of 
  willows. 
  In 
  the 
  

   upper 
  part 
  of 
  the 
  zone, 
  the 
  formation 
  becomes 
  more 
  and 
  more 
  

   like 
  the 
  willow 
  bogs 
  of 
  the 
  Subalpine 
  Zone.
