  ferred 
  to, 
  which 
  unite 
  in 
  a 
  deep 
  valley 
  directly 
  beneath 
  Ute 
  Peak 
  and 
  

   only 
  two 
  miles 
  east 
  of 
  it. 
  That 
  branch, 
  which 
  might 
  be 
  considered 
  the 
  

   main 
  branch, 
  flows 
  along 
  the 
  eastern 
  base 
  of 
  Williams 
  Range 
  from 
  its 
  

   very 
  intersection 
  with 
  the 
  main 
  range 
  down 
  to 
  the 
  vicinity 
  of 
  Ute 
  Pass. 
  

   All 
  the 
  branches 
  as 
  long 
  as 
  remaining 
  in 
  the 
  upper 
  region 
  are 
  confined 
  

   and 
  inclosed 
  within 
  canons, 
  and 
  only 
  when 
  Williams 
  River 
  arrives 
  at 
  

   the 
  parallel 
  of 
  Ute 
  Pass 
  it 
  is 
  freed, 
  as 
  well 
  as 
  the 
  other 
  tributaries, 
  from 
  

   a 
  too 
  close 
  proximity 
  of 
  the 
  mountains. 
  This 
  is 
  at 
  least 
  the 
  case 
  on 
  the 
  

   west 
  side 
  of 
  the 
  river, 
  where, 
  from 
  the 
  Ute 
  Pass 
  downward, 
  the 
  slopes 
  

   of 
  Williams 
  Range 
  approach 
  the 
  river 
  with 
  a 
  more 
  gentle 
  descent 
  than 
  

   above. 
  The 
  right 
  bank 
  of 
  Williams 
  River, 
  or 
  the 
  east 
  side, 
  is 
  bordered 
  

   by 
  the 
  outrunners 
  of 
  granite 
  spurs 
  coming 
  from 
  Mount 
  Byers 
  and 
  the 
  

   upper 
  region 
  of 
  the 
  Vasquez 
  Ridge. 
  This 
  feature 
  exists 
  all 
  along 
  the 
  

   middle 
  part 
  of 
  Williams 
  River 
  during 
  a 
  length 
  of 
  7 
  to 
  8 
  miles. 
  The 
  left 
  

   or 
  western 
  river-bank 
  gains 
  continually 
  in 
  width 
  from 
  the 
  time 
  the 
  river 
  

   leaves 
  the 
  vicinity 
  of 
  Ute 
  Pass, 
  and 
  when 
  it 
  arrives 
  at 
  a 
  point 
  in 
  the 
  

   valley 
  about 
  10 
  miles 
  south 
  from 
  its 
  junction 
  with 
  the 
  Grand, 
  the 
  Will- 
  

   iams 
  Basin 
  attains 
  its 
  greatest 
  width 
  and 
  retains 
  the 
  same 
  for 
  8 
  miles 
  

   further 
  down 
  the 
  stream. 
  Gentle 
  terraced 
  and 
  grassy 
  slopes 
  run 
  from 
  

   the 
  river-bed 
  gradually 
  westward 
  toward 
  Williams 
  Range, 
  the 
  back- 
  

   bone 
  of 
  which 
  lies 
  about 
  6 
  miles 
  from 
  the 
  river. 
  All 
  along 
  from 
  near 
  

   its 
  sources 
  Williams 
  River 
  has 
  followed 
  a 
  northwest 
  course, 
  but 
  when 
  ar- 
  

   riving 
  within 
  a 
  few 
  miles 
  of 
  the 
  Grand 
  it 
  makes 
  a 
  sudden 
  turn 
  to 
  the 
  

   right 
  or 
  east, 
  and 
  in 
  breaking 
  through 
  a 
  connected 
  ridge 
  of 
  buttes 
  or 
  

   high 
  terraces 
  which 
  border 
  the 
  southern 
  margin 
  of 
  the 
  Grand, 
  forms 
  a 
  

   canon 
  for 
  2^ 
  miles, 
  which 
  ceases 
  when 
  very 
  close 
  to 
  its 
  junction 
  with 
  

   the 
  Grand. 
  The 
  total 
  length 
  of 
  Williams 
  River 
  is 
  34 
  miles, 
  and, 
  includ- 
  

   ing 
  the 
  higher 
  mountain 
  district 
  where 
  great 
  fall 
  exists, 
  its 
  average 
  

   fall 
  amounts 
  to 
  112 
  feet, 
  but 
  from 
  the 
  vicinity 
  of 
  Ute 
  Peak 
  down 
  to 
  its 
  

   junction 
  with 
  the 
  Grand, 
  a 
  distance 
  of 
  18 
  miles, 
  Williams 
  River 
  has 
  

   hardly 
  an 
  average 
  fall 
  of 
  over 
  60 
  feet 
  per 
  mile. 
  

  

  There 
  is 
  another 
  creek 
  coming 
  from 
  the 
  north 
  which 
  faces 
  Williams 
  

   River 
  and 
  enters 
  the 
  Grand 
  only 
  a 
  half 
  mile 
  below 
  the 
  junction 
  of 
  Will- 
  

   iams 
  and 
  the 
  Grand, 
  which 
  is 
  named 
  

  

  CORRAL 
  CREEK. 
  

  

  This 
  stream 
  has 
  a 
  length 
  of 
  12 
  miles, 
  and 
  originates 
  between 
  Corral 
  

   and 
  Whiteface 
  Peaks. 
  The 
  principal 
  characteristics 
  of 
  this 
  stream 
  are 
  

   those 
  of 
  a 
  mountain-creek 
  wjith 
  a 
  comparative 
  rapid 
  descent 
  during 
  its 
  

   whole 
  course. 
  This 
  rapid 
  descent 
  shows 
  at 
  once 
  the 
  improbability 
  of 
  

   the 
  development 
  of 
  any 
  regular 
  valley 
  feature. 
  While 
  in 
  the 
  mountains, 
  

   the 
  narrow 
  valley 
  shows 
  grassy 
  margins, 
  and 
  during 
  its 
  whole 
  course 
  

   here 
  and 
  there 
  very 
  small 
  patches 
  of 
  bottom-land. 
  Its 
  course 
  is 
  very 
  

   direct, 
  and 
  nearly 
  north 
  and 
  south. 
  Its 
  average 
  fall 
  is 
  about 
  200 
  feet 
  

   per 
  mile 
  and 
  the 
  total 
  fall 
  2,400 
  feet. 
  

  

  Six 
  miles 
  and 
  a 
  half 
  below 
  Corral 
  Creek 
  the 
  Grand 
  receives 
  another 
  

   tributary, 
  namely, 
  

  

  THE 
  TROUBLESOME 
  RIVER. 
  

  

  The 
  eastern 
  and 
  western 
  forks 
  of 
  this 
  stream 
  join 
  about 
  8 
  miles 
  north 
  

   of 
  its 
  junction 
  with 
  the 
  Grand. 
  The 
  eastern 
  branch 
  has 
  two 
  prongs 
  

   near 
  its 
  headwaters 
  ; 
  the 
  source 
  of 
  one 
  drains 
  the 
  western 
  and 
  southern 
  

   slopes 
  of 
  Park 
  View 
  Mountain, 
  and 
  the 
  other 
  originates 
  among 
  the 
  

   peaks 
  and 
  s])urs 
  detached 
  from 
  the 
  Continental 
  Divide 
  several 
  miles 
  

   west 
  of 
  Park 
  View 
  Mountain. 
  After 
  their 
  junction, 
  the 
  river 
  flows
