  Conclusions. 
  

  

  The 
  most 
  important 
  new 
  stratigraphical 
  facts 
  discov- 
  

   ered 
  by 
  this 
  exploration 
  are 
  the 
  following 
  : 
  

  

  1. 
  The 
  lower 
  red 
  beds 
  of 
  the 
  Sangre

  Moun- 
  

  

  tains, 
  at 
  the 
  southern 
  end 
  of 
  the 
  Rocky 
  Mountains 
  

   proper, 
  belong 
  to 
  the 
  Abo 
  formation 
  of 
  the 
  Man- 
  

   zano 
  Group. 
  

  

  2. 
  The 
  lower 
  part 
  of 
  the 
  Abo 
  formation 
  is 
  upper 
  Penn- 
  

  

  sylvanian 
  in 
  age. 
  

  

  3. 
  The 
  Yeso 
  formation 
  and 
  San 
  Andreas 
  limestone 
  are 
  

  

  lower 
  Permian 
  in 
  age. 
  

  

  4. 
  The 
  Guadalupian-Pecos 
  Valley 
  red 
  beds 
  series 
  lies 
  un- 
  

  

  conformably 
  upon 
  strata 
  of 
  the 
  Manzano 
  Group. 
  

  

  5. 
  The 
  Glorieta 
  sandstone 
  is 
  the 
  basal 
  part

  6. 
  The 
  age 
  of

  lished 
  as 
  Middle 
  or 
  Upper 
  Cenomanian.

  A 
  coarse 
  detrital 
  facies 
  of 
  the 
  Benton 
  rests 
  directly 
  

  

  upon 
  Manzano 
  rocks 
  in 
  central-southern 
  New 
  

   Mexico.
