﻿REPORT 
  OF 
  THE 
  SECRETARY. 
  7 
  

  

  in 
  Ranger 
  Brook 
  Canyon 
  and 
  to 
  conduct 
  a 
  reconnaissance 
  of 
  the 
  

   pre- 
  Devonian 
  formations 
  to 
  the 
  Northwest 
  as 
  far 
  as 
  the 
  headwaters 
  

   of 
  the 
  North 
  Fork 
  of 
  the 
  Saskatchewan 
  River, 
  Alberta. 
  

  

  The 
  field 
  season 
  was 
  an 
  unusually 
  unfavorable 
  one 
  for 
  geological 
  

   work. 
  During 
  the 
  three 
  months 
  in 
  the 
  field 
  35 
  days 
  were 
  stormy, 
  

   28 
  cloudy 
  and 
  cold, 
  and 
  snow 
  fell 
  on 
  20 
  days 
  in 
  August 
  and 
  Sep- 
  

   tember. 
  As 
  a 
  result, 
  not 
  more 
  than 
  one-third 
  of 
  the 
  work 
  planned 
  

   was 
  accomplished 
  before 
  the 
  party 
  was 
  driven 
  back 
  to 
  the 
  railroad 
  

   by 
  heavy 
  snows. 
  

  

  On 
  our 
  way 
  north 
  we 
  crossed 
  over 
  Pipestone 
  Pass 
  and 
  down 
  the 
  

   Siffleur 
  River. 
  Clearwater 
  River 
  heads 
  in 
  glacial 
  gravels 
  on 
  the 
  

   east 
  side 
  of 
  the 
  Siffleur 
  about 
  2 
  miles 
  north 
  of 
  Pipestone 
  Pass. 
  

   Twenty-five 
  miles 
  farther 
  to 
  the 
  northwest 
  at 
  the 
  point 
  where 
  the 
  

   south 
  branch 
  (Mistaya 
  Creek), 
  the 
  middle 
  branch 
  (Howse 
  River), 
  

   and 
  the 
  north 
  branch 
  unite 
  to 
  form 
  the 
  Saskatchewan 
  River 
  there 
  

   are 
  some 
  beautiful 
  and 
  instructive 
  views 
  of 
  the 
  surrounding 
  moun- 
  

   tains. 
  The 
  Mount 
  Forbes 
  massif 
  on 
  the 
  left 
  is 
  a 
  superb 
  mountain 
  

   mass 
  and 
  in 
  the 
  distant 
  center 
  is 
  Division 
  Mountain 
  at 
  the 
  head 
  of 
  

   Glacier 
  Lake 
  Canyon 
  which 
  we 
  visited 
  in 
  1919, 
  on 
  the 
  right 
  Survey 
  

   Peak 
  and 
  beyond 
  two 
  unnamed 
  points. 
  The 
  Glacier 
  Lake 
  section 
  

   of 
  the 
  pre-Devonian 
  and 
  Upper 
  Cambrian 
  formations 
  was 
  studied 
  

   on 
  the 
  northern 
  slopes 
  of 
  the 
  Mount 
  Forbes 
  massif. 
  

  

  Twelve 
  miles 
  northeast 
  of 
  Mount 
  Forbes 
  the 
  cliffs 
  of 
  Mount 
  

   Murchison 
  rise 
  high 
  above 
  the 
  dark 
  forested 
  slopes 
  and 
  present 
  a 
  

   view 
  of 
  the 
  Devonian 
  and 
  pre-Devonian 
  formations 
  that 
  is 
  un- 
  

   equaled 
  in 
  all 
  this 
  region 
  of 
  peaks, 
  cliffs, 
  and 
  broad 
  canyon 
  valleys. 
  

  

  Opposite 
  Mount 
  Murchison 
  on 
  the 
  north 
  side 
  of 
  the 
  Saskatchewan, 
  

   Mount 
  Wilson 
  presents 
  another 
  section 
  of 
  the 
  pre-Devonian 
  forma- 
  

   tions, 
  the 
  upper 
  end 
  of 
  which 
  is 
  a 
  massive 
  white 
  quartzite 
  formed 
  

   of 
  the 
  sands 
  of 
  the 
  beaches 
  over 
  which 
  the 
  Devonian 
  Sea 
  deposited 
  

   a 
  thick 
  layer 
  of 
  calcareous 
  sediments 
  abounding 
  in 
  the 
  remains 
  of 
  

   corals 
  and 
  various 
  invertebrates 
  of 
  the 
  time. 
  On 
  the 
  west, 
  Mount 
  

   Wilson 
  rises 
  directly 
  above 
  the 
  North 
  Fork 
  of 
  the 
  Saskatchewan, 
  

   which 
  here 
  flows 
  through 
  a 
  narrow 
  picturesque 
  inner 
  canyon. 
  

  

  PALEONTOLOGICAL, 
  FIELD 
  WORK 
  IN 
  THE 
  UNITED 
  STATES. 
  

  

  Dr. 
  R. 
  S. 
  Bassler, 
  curator 
  of 
  the 
  division 
  of 
  paleontology 
  in 
  the 
  

   National 
  Museum, 
  was 
  occupied 
  during 
  the 
  field 
  season 
  in 
  collecting 
  

   geologic 
  material 
  and 
  in 
  mapping 
  and 
  studying 
  the 
  economic 
  re- 
  

   sources 
  of 
  the 
  Franklin 
  quadrangle 
  in 
  Williamson 
  County, 
  Tenn., 
  

   in 
  cooperation 
  with 
  the 
  Geological 
  Survey 
  of 
  that 
  State. 
  This 
  region 
  

   is 
  of 
  considerable 
  economic 
  interest 
  on 
  account 
  of 
  the 
  phosphate 
  

   and 
  oil 
  shale 
  possibilities. 
  The 
  numerous 
  outcrops 
  of 
  Ordovician 
  

   and 
  later 
  Paleozoic 
  formations 
  contain 
  a 
  great 
  number 
  of 
  fossils,
