  Report 
  on 
  the 
  Petrified 
  Forests 
  of 
  Arizona 
  ; 
  by 
  Lester 
  F. 
  

   Ward, 
  Department 
  of 
  the 
  Interior, 
  Washington, 
  1900. 
  — 
  The 
  

   present 
  report 
  was 
  made 
  in 
  compliance 
  with 
  instructions 
  from 
  the 
  

   Director 
  of 
  the 
  United 
  States 
  Geological 
  Survey 
  especially 
  with 
  

   reference 
  to 
  the 
  proposition 
  to 
  set 
  aside 
  the 
  region 
  embracing 
  the 
  

   Petrified 
  Forests 
  as 
  a 
  national 
  park. 
  

  

  The 
  Petrified 
  Forest, 
  or 
  Chalcedony 
  Park, 
  or 
  Lithodendron 
  

   (stone 
  tree) 
  Valley, 
  as 
  it 
  has 
  been 
  variously 
  called, 
  is 
  situated 
  in 
  

   Apache 
  County, 
  Arizona, 
  between 
  the 
  Little 
  Colorado 
  and 
  the 
  

   Rio 
  Puerco, 
  fifteen 
  miles 
  east 
  of 
  their 
  junction, 
  seventeen 
  miles 
  

   east 
  of 
  Holbrook, 
  and 
  six 
  miles 
  south 
  of 
  Adamana 
  station 
  on 
  the 
  

   Santa 
  Fe 
  Pacific 
  Railroad. 
  The 
  area 
  in 
  which 
  the 
  fossil 
  conifer- 
  

   ous 
  trunks 
  are 
  particularly 
  abundant 
  is 
  about 
  eight 
  miles 
  square, 
  

   though 
  at 
  other 
  points 
  in 
  the 
  same 
  Triassic 
  terrane 
  in 
  Arizona, 
  

   New 
  Mexico 
  and 
  Utah, 
  much 
  silicified 
  wood 
  occurs. 
  

  

  As 
  the 
  result 
  of 
  his 
  visit 
  during 
  the 
  preceding 
  summer, 
  Pro- 
  

   fessor 
  Ward 
  fully 
  confirms 
  the 
  various 
  descriptions 
  of 
  the 
  extent 
  

   and 
  wonderful 
  character 
  of 
  the 
  gigantic 
  silicified 
  Arizona 
  forest. 
  

   Its 
  interest, 
  moreover, 
  is 
  much 
  enhanced 
  by 
  the 
  fact 
  that 
  it 
  is 
  

   very 
  old, 
  probably 
  of 
  Triassic 
  age. 
  The 
  great 
  fossil 
  forests 
  of 
  

   California 
  and 
  the 
  Yellowstone 
  Park 
  are 
  Tertiary 
  and 
  compared 
  

   with 
  those 
  of 
  Arizona 
  of 
  comparatively 
  recent 
  date;
