  drainage 
  depressions 
  in 
  the 
  hills 
  show 
  even 
  no 
  evidence 
  of 
  water-flow 
  

   during 
  any 
  part 
  of 
  the 
  season, 
  as 
  I 
  have 
  found 
  no 
  furrow 
  or 
  drainage- 
  

   bed 
  where 
  water 
  had 
  once 
  flowed, 
  only 
  moist, 
  grassy 
  places, 
  with 
  some 
  

   pools 
  of 
  accumulated 
  water, 
  here 
  and 
  there. 
  

  

  When 
  Tarry 
  all 
  Creek 
  arrives 
  at 
  the 
  point 
  7 
  miles 
  below 
  the 
  junction 
  of 
  

   Eock 
  and 
  Tarryall 
  Creeks, 
  it 
  is 
  closely 
  pressed 
  by 
  mountains 
  on 
  both 
  

   sides 
  for 
  a 
  distance 
  of 
  about 
  7 
  miles, 
  but 
  not 
  so 
  much 
  that 
  the 
  road 
  lead- 
  

   ing 
  along 
  this 
  creek 
  would 
  be 
  obliged 
  to 
  leave 
  the 
  valley 
  and 
  follow 
  

   along 
  the 
  mountain 
  spurs. 
  We 
  And 
  no 
  ranches 
  within 
  4 
  miles 
  of 
  this 
  

   caiion 
  valley; 
  but 
  after 
  that 
  it 
  opens, 
  and 
  remains 
  so 
  for 
  2 
  miles, 
  so 
  as 
  

   to 
  give 
  room 
  for 
  the 
  location 
  of 
  several 
  ranches. 
  Near 
  the 
  end 
  of 
  

   the 
  2 
  miles 
  the 
  mountains 
  recede 
  on 
  the 
  west 
  side 
  to 
  a 
  distance 
  of 
  8 
  

   miles, 
  thus 
  making 
  the 
  country 
  more 
  generally 
  open, 
  but 
  not 
  level, 
  

   for 
  numerous 
  small 
  hills 
  of 
  granite, 
  several 
  hundred 
  feet 
  high, 
  crowd 
  

   near 
  the 
  creek 
  and 
  give 
  it 
  a 
  caSonlike 
  margin, 
  while 
  on 
  the 
  east 
  the 
  

   creek 
  is 
  bordered 
  by 
  the 
  very 
  bases 
  of 
  huge 
  granite 
  slopes 
  from 
  the 
  

   Tarryall 
  Range. 
  

  

  The 
  Tarryall 
  has, 
  all 
  the 
  distance 
  from 
  Eock 
  Creek, 
  about 
  22 
  miles, 
  a 
  

   southeast 
  course, 
  after 
  which 
  it 
  suddenly 
  turns 
  to 
  the 
  east. 
  After 
  

   meandering 
  for 
  4 
  miles 
  in 
  a 
  rugged 
  canon, 
  it 
  enters 
  the 
  South 
  Platte 
  

   !]Eiiver. 
  The 
  whole 
  length 
  of 
  Tarryall 
  Creek, 
  from 
  its 
  source 
  near 
  Ham- 
  

   ilton 
  Pass, 
  is 
  48 
  miles, 
  with 
  a 
  total 
  fall 
  of 
  4,200 
  feet, 
  and 
  an 
  average 
  

   fall 
  of 
  137 
  feet 
  per 
  mile. 
  The 
  scenery 
  along 
  the 
  more 
  southern 
  part 
  of 
  

   the 
  Tarryall 
  Range 
  is 
  truly 
  grand 
  and 
  gorgeous. 
  Huge 
  reddish 
  granite 
  

   masses, 
  and 
  in 
  the 
  most 
  rugged 
  shape, 
  are 
  here 
  visible, 
  rising 
  abruptly 
  

   to 
  a 
  mean 
  height 
  of 
  2,200 
  feet 
  above 
  the 
  valley, 
  so 
  as 
  to 
  baffle 
  in 
  most 
  

   places 
  any 
  human 
  attempt 
  to 
  scale 
  them. 
  Only 
  in 
  the 
  center 
  of 
  the 
  

   valley 
  have 
  we 
  been 
  able 
  to 
  find 
  a 
  place 
  where, 
  with 
  some 
  elibrt, 
  we 
  

   were 
  able 
  to 
  make 
  the 
  ascent 
  with 
  animals. 
  

  

  LOST 
  PARK. 
  

  

  Between 
  Tarryall 
  Range 
  on 
  the 
  west 
  and 
  Kanosha 
  Range 
  on 
  the 
  north 
  

   and 
  northeast, 
  there 
  lies 
  another 
  high 
  mountain 
  valley, 
  apparently 
  char- 
  

   acteristic 
  only 
  of 
  that 
  portion 
  of 
  the 
  country. 
  This 
  valley, 
  separated 
  

   from 
  Creig 
  Creek 
  only 
  by 
  the 
  width 
  of 
  the 
  Kanosha 
  Range, 
  lies 
  but 
  

   four 
  miles 
  south 
  of, 
  and 
  but2,00u 
  feet 
  lower 
  than, 
  Creig's 
  high 
  mountain 
  

   valley. 
  Its 
  mean 
  elevation 
  above 
  sea-level 
  is 
  9,200 
  feet. 
  Inclosed 
  on 
  

   all 
  sides 
  by 
  high 
  and 
  rugged 
  mountains, 
  and 
  having 
  as 
  yet 
  only' 
  two 
  

   very 
  steep, 
  rocky, 
  and 
  imperfect 
  approaches, 
  namely. 
  Rock 
  Creek 
  and 
  

   Wigwam 
  Creek 
  trails, 
  hunters 
  and 
  prospectors 
  have 
  named 
  that 
  

   mountain 
  valley 
  " 
  Lost 
  Park," 
  perhaps 
  from 
  its 
  seclusion. 
  To 
  the 
  for- 
  

   midable 
  creek 
  that 
  meanders 
  through 
  that 
  valley, 
  the 
  name 
  of 
  " 
  Lost 
  

   Park 
  Creek 
  " 
  has 
  been 
  attached 
  for 
  want 
  of 
  a 
  better 
  one. 
  Where 
  Tariyall 
  

   and 
  Kanosha 
  are 
  linked 
  together 
  by 
  means 
  of 
  a 
  low 
  saddle, 
  the 
  Lost 
  Park 
  

   (main) 
  Creek 
  takes 
  its 
  rise. 
  Only 
  half 
  a 
  mile 
  farther 
  to 
  the 
  north 
  another 
  

   creek, 
  Indian 
  Creek, 
  originates, 
  draining 
  the 
  western 
  slopes 
  of 
  Ka- 
  

   nosha 
  Range. 
  Only 
  three-fourths 
  of 
  a 
  mile 
  apart 
  from 
  each 
  other, 
  and 
  

   separated 
  only 
  by 
  a 
  low 
  ridge, 
  the 
  two 
  creeks 
  flow, 
  with 
  a 
  moderate 
  de- 
  

   scent, 
  along 
  side 
  by 
  side 
  to 
  unite 
  5 
  miles 
  below, 
  where 
  the 
  lull 
  character- 
  

   istics 
  of 
  a 
  valley 
  or 
  park 
  manifest 
  themselves. 
  Indications 
  of 
  a 
  valley 
  

   character 
  exist, 
  however, 
  already 
  on 
  the 
  main 
  stream 
  nearly 
  all 
  the 
  way 
  

   up 
  toKock 
  Creek 
  saddle. 
  This 
  creek 
  receives 
  also 
  some 
  lateral 
  streams 
  

   from 
  the 
  gently-sloping 
  willow-flats 
  on 
  the 
  northeast 
  slope 
  of 
  Upper 
  

   Tairyall 
  Range. 
  Before 
  the 
  two 
  streams 
  which 
  have 
  their 
  sources 
  near 
  

   and 
  about 
  Rock 
  Creek 
  saddle 
  unite, 
  the 
  western 
  creek 
  or 
  main 
  stream
