  feet) 
  suddenly 
  to 
  the 
  lofty 
  elevation 
  of 
  14,336 
  

   feet. 
  Torrey's 
  Peak 
  is 
  only 
  3,900 
  feet 
  distant 
  from 
  Gray's 
  Peak, 
  and 
  

   connected 
  with 
  the 
  latter 
  by 
  a 
  saddle. 
  The 
  peaks 
  along 
  the 
  crest 
  be- 
  

   tween 
  James 
  and 
  Torrey 
  Peaks 
  are 
  limited 
  to 
  the 
  number 
  of 
  about 
  24, 
  

   which 
  are 
  of 
  an 
  average 
  height 
  of 
  12,700 
  feet. 
  

  

  Gray's 
  and 
  Torrey's 
  are 
  the 
  center 
  peaks 
  or 
  culminating 
  points 
  of 
  a 
  

   mountain 
  mass 
  concentrated 
  at 
  that 
  jjoint. 
  From 
  this 
  center 
  a 
  great 
  

   subridge, 
  an 
  imposing 
  huge 
  mountain 
  mass, 
  is 
  sent 
  forth 
  in 
  an 
  east- 
  

   erly 
  direction, 
  of 
  which 
  Mount 
  Evans, 
  14,130 
  feet 
  in 
  height, 
  and 
  distant 
  

   from 
  Gray's 
  Peak 
  10 
  miles, 
  is 
  the 
  culminating 
  point. 
  From 
  the 
  latter 
  

   peak, 
  subridges 
  of 
  a 
  second 
  and 
  third 
  order 
  are 
  again 
  detached, 
  which 
  

   press 
  forward 
  toward 
  the 
  plain, 
  between 
  the 
  different

  Gray 
  and 
  

   Torrey, 
  with 
  an 
  absolute 
  height 
  of 
  14,336 
  feet, 
  stand 
  also 
  in 
  the 
  center 
  

   of 
  bold, 
  rich, 
  and 
  varied 
  mountain 
  scenery, 
  the 
  reputation 
  of 
  which 
  has 
  

   alreadj" 
  gone 
  beyond 
  the 
  borders 
  of 
  our 
  country. 
  

  

  From 
  Gray's 
  Peak 
  to 
  Mount 
  Lincoln, 
  the 
  length 
  of 
  the 
  crest 
  of 
  the 
  

   main 
  Colorado 
  Range 
  is 
  42 
  miles. 
  Only 
  2^ 
  miles 
  east 
  of 
  Gray's 
  Peak 
  

   lies 
  Argentine 
  Pass, 
  13,000 
  feet 
  in 
  height, 
  over 
  which 
  the 
  highest 
  known 
  

   wagon-road 
  in 
  Colorado 
  crosses 
  the 
  Rocky 
  Mountain 
  Range 
  from 
  George- 
  

   town 
  to 
  mining 
  settlements 
  in 
  and 
  about 
  the 
  head 
  of 
  Blue 
  River 
  Valley. 
  

   Others, 
  such 
  as 
  Hand 
  Cart, 
  Georgia, 
  Hamilton 
  (sometimes 
  called 
  Breck- 
  

   enridge), 
  and 
  Hoosier 
  Passes, 
  cross 
  the 
  divide 
  between 
  Gray's 
  Peak 
  

   and 
  Mount 
  Lincoln. 
  The 
  average 
  height 
  of 
  this 
  crest 
  is 
  12,570 
  feet, 
  

   which 
  shows 
  a 
  higher 
  average 
  for 
  the 
  crest 
  than 
  in 
  any 
  previous 
  de- 
  

   scribed 
  part 
  of 
  this 
  range, 
  and 
  numerous 
  peaks 
  of 
  the 
  first 
  order, 
  among 
  

   them 
  Whale 
  Peak, 
  Mount 
  Guyot, 
  Mount 
  Hamilton, 
  and 
  Silverheel 
  

   Mountain, 
  confer 
  no 
  monotonous 
  character 
  on 
  the 
  escarpment 
  of 
  this 
  

   part 
  of 
  the 
  range. 
  

  

  About 
  15^ 
  miles 
  south 
  of 
  Gray's 
  Peak 
  a 
  subrange 
  departs 
  in 
  a 
  south- 
  

   east 
  direction, 
  which 
  leads 
  toward 
  Kanosha 
  Pass, 
  and 
  connects 
  imme- 
  

   diately 
  beyond 
  that 
  pass 
  with 
  the 
  Kanosha 
  and 
  Tarryall 
  Ranges. 
  From 
  

   Whale 
  Peak, 
  13,104 
  feet, 
  the 
  main 
  Colorado 
  range 
  takes 
  its 
  course 
  in 
  a 
  

   due 
  southwesterly 
  direction, 
  until 
  it 
  reaches 
  the 
  Silverheel 
  group, 
  from 
  

   whence 
  its 
  course 
  is 
  due 
  westward 
  across 
  the 
  Park 
  Range 
  to 
  Tennessee 
  

   Pass 
  and 
  Homestake 
  Peak. 
  

  

  From 
  Argentine 
  Pass 
  to 
  Whale 
  Peak, 
  a 
  distance 
  of 
  15 
  miles, 
  the 
  crest 
  

   shows 
  a 
  succession 
  of 
  peaks, 
  which 
  nearly 
  all 
  average 
  the 
  height 
  of 
  

   13,000 
  feet. 
  Southwest 
  of 
  Whale 
  Peak, 
  a 
  slight 
  depression 
  occurs 
  on 
  

   the 
  range 
  which 
  finds 
  its 
  minimum 
  altitude 
  at 
  Georgia 
  Pass, 
  11,500 
  

   feet, 
  from 
  which 
  point, 
  however, 
  the 
  slopes 
  of 
  Mount 
  Guyot 
  rise 
  again 
  

   to 
  13,565 
  feet. 
  Mount 
  Guyot, 
  as 
  well 
  as 
  Mount 
  Hamilton, 
  lies 
  in 
  the 
  

   center 
  of 
  the 
  Rocky 
  Mountain 
  escarpment. 
  Both 
  are 
  of 
  nearly 
  equal 
  

   height, 
  yet 
  they 
  are 
  different 
  in 
  form 
  and 
  aspect, 
  Mount 
  Guyot 
  assum- 
  

   ing 
  a 
  pyramidal 
  shape, 
  while 
  Mount 
  Hamilton 
  takes 
  a 
  huge 
  and 
  singu- 
  

   larly 
  shaped 
  hogback 
  form, 
  with 
  an 
  axis 
  running 
  north 
  and 
  south. 
  

   Both 
  mountains 
  are 
  separated 
  by 
  a 
  saddle 
  depression 
  of 
  about 
  1,500 
  feet, 
  

   and 
  both 
  are 
  of 
  a 
  commanding 
  appearance 
  and 
  are 
  easily 
  recognized 
  

   points, 
  particularly 
  from 
  the 
  north 
  and 
  northwest. 
  We 
  find 
  on 
  the 
  north 
  

   slope 
  of 
  the 
  main 
  Colorado 
  Range, 
  between 
  Argentine 
  Pass 
  and 
  Hamil- 
  

   ton 
  Pass, 
  a 
  total 
  of 
  mountain 
  spurs, 
  which 
  represent 
  a 
  length 
  of 
  58 
  

   miles, 
  linear 
  measure, 
  while 
  on 
  the 
  southern 
  slope 
  the 
  mass 
  of 
  spurs 
  

   amount 
  to 
  OS 
  miles. 
  From 
  Whale 
  Peak 
  a 
  spur 
  with 
  eight 
  peaks, 
  vary- 
  

   ing 
  from 
  12,400 
  to 
  12,600 
  feet 
  in 
  height, 
  spread 
  in 
  zigzag 
  form 
  toward 
  

   Snake 
  River, 
  with 
  many 
  smaller 
  wings 
  branching 
  off" 
  to 
  the 
  right 
  and 
  to 
  

   the 
  left. 
  One 
  of 
  these 
  wings 
  is 
  crowned 
  with 
  three 
  peaks.
