  THE 
  SOUTHEASTERN 
  DISTRICT.

  10,570 
  feet 
  above 
  sea-level. 
  The 
  next 
  trail 
  crossing 
  the 
  range 
  follows 
  

   up 
  the 
  South 
  Fork 
  of 
  the 
  Eio 
  Grande, 
  wends 
  its 
  way 
  through 
  the 
  mount- 
  

   ains, 
  and, 
  striking 
  the 
  head 
  of 
  the 
  main 
  San 
  Juan, 
  follows 
  it 
  down 
  to 
  

   Pagosa 
  Springs, 
  This 
  trail 
  has 
  been 
  used 
  but 
  little 
  of 
  late 
  years 
  by 
  

   the 
  Indians, 
  and 
  is, 
  therefore, 
  quite 
  dim 
  in 
  some 
  places. 
  The 
  pass 
  has 
  

   an 
  elevation 
  of 
  about 
  11,200 
  feet. 
  

  

  The 
  most 
  southerly 
  pass 
  in 
  our 
  district 
  is 
  crossed 
  by 
  a 
  very 
  well 
  used 
  

   trail 
  which 
  follows 
  up 
  Eio 
  San 
  Antonio 
  from 
  Conejos, 
  crosses 
  the 
  head- 
  

   waters 
  of 
  the 
  Brazos, 
  thence 
  down 
  one 
  of 
  the 
  spurs 
  to 
  Tierra 
  Amarilla. 
  

   The 
  highest 
  point 
  on 
  this 
  trail 
  is 
  about 
  10,000 
  feet 
  above 
  sea-level. 
  It 
  

   is 
  used 
  by 
  the 
  settlers 
  to 
  considerable 
  extent 
  in 
  driving 
  their 
  sheep 
  to 
  

   the 
  San 
  Luis 
  Valley 
  and 
  thence 
  eastward 
  ; 
  but 
  their 
  supplies 
  and 
  uten- 
  

   sils 
  are 
  transported 
  by 
  wagon 
  over 
  a 
  pass 
  to 
  the 
  south. 
  

  

  The 
  region 
  of 
  country 
  to 
  the 
  west 
  of 
  the 
  high 
  mountains 
  examined 
  

   by 
  this 
  x)arty 
  is 
  made 
  up 
  of 
  broken 
  hills, 
  flat 
  table-like 
  mesas, 
  and 
  small 
  

   valleys. 
  The 
  hills 
  are 
  generally 
  covered 
  with 
  a 
  thin 
  growth 
  of 
  piiions 
  

   and 
  cedara, 
  while 
  along 
  the 
  foot 
  of 
  the 
  mountains 
  there 
  is 
  a 
  very 
  good 
  

   growth 
  of 
  yellow 
  pine. 
  The 
  valleys 
  along 
  the 
  streams 
  are 
  generally 
  

   very 
  rich, 
  and 
  as 
  the 
  heights 
  of 
  these 
  valleys 
  are 
  not 
  very 
  great, 
  they 
  

   will 
  be 
  found 
  very 
  productive. 
  All 
  of 
  this 
  region 
  west 
  of 
  the 
  San 
  Juan 
  

   Mountains 
  is 
  drained 
  by 
  the 
  San 
  Juan 
  Eiver 
  and 
  its 
  tributaries. 
  

  

  I 
  will 
  not 
  attempt 
  here 
  to 
  give 
  any 
  detailed 
  description 
  of 
  the 
  district, 
  

   but 
  will 
  refer 
  the 
  reader 
  to 
  the 
  appended 
  report 
  of 
  Franklin 
  Ehoda, 
  in 
  

   which 
  will 
  be 
  found 
  a 
  more 
  detailed 
  description 
  of 
  the 
  country 
  we 
  

   exi)lored. 
  

  

  I 
  will 
  refer 
  the 
  reader 
  to 
  the 
  report 
  of 
  Dr. 
  F. 
  M. 
  Endlich, 
  geologist 
  of 
  

   the 
  party, 
  for 
  any 
  information 
  that 
  may 
  be 
  desired 
  in 
  reference 
  to 
  geo- 
  

   logical 
  or 
  mineralogical 
  features. 
  

  

  The 
  accompanying 
  drainage-map 
  of 
  Colorado 
  was 
  compiled 
  from 
  the 
  

   final 
  sheets, 
  and 
  reduced 
  to 
  a 
  small 
  scale 
  in 
  order 
  that 
  it 
  might 
  not 
  be 
  

   cumbersome 
  in 
  size. 
  Much 
  of 
  the 
  minor 
  details 
  have 
  been 
  omitted 
  to 
  

   avoid 
  confusion, 
  giving 
  only 
  the 
  water-courses, 
  principal 
  mountain- 
  

   peaks, 
  roads, 
  trails, 
  towns, 
  «Sjc. 
  The 
  heights 
  of 
  all 
  the 
  more 
  important 
  

   points 
  are 
  indicated 
  by 
  figures 
  placed 
  thereby.
