  with 
  timber, 
  and 
  its 
  subspurs 
  extend, 
  with 
  considerable 
  ruggedness 
  

   and 
  massiveness, 
  toward 
  Willow 
  Creek, 
  where, 
  by 
  their 
  sudden 
  slope 
  

   and 
  corresponding 
  steep 
  faces 
  on 
  the 
  opposite 
  side 
  of 
  Willow 
  Creek, 
  

   they 
  give 
  the 
  latter 
  stream 
  the 
  unmistakable 
  appearance 
  of 
  a 
  canon. 
  

  

  In 
  a 
  direct 
  southern 
  direction 
  toward 
  the 
  Middle 
  Park 
  the 
  slopes 
  are 
  

   more 
  gradual, 
  while 
  again 
  toward 
  the 
  valley 
  of 
  the 
  Grand 
  the 
  slopes 
  are 
  

   abrupt. 
  ■ 
  The 
  highest 
  points 
  of 
  this 
  mountain 
  mass 
  show 
  a 
  relative 
  

   height 
  of 
  4,200 
  feet 
  above 
  the 
  valley 
  of 
  the 
  Upper 
  Grand 
  Eiver, 
  while 
  

   the 
  average 
  crest 
  height 
  is 
  3,600 
  feet 
  above 
  the 
  latter 
  valley.
