  The 
  rocks 
  are 
  red 
  sandstones 
  almost 
  vermilion 
  in 
  

   color, 
  whence 
  the 
  name 
  of 
  the 
  creek, 
  which 
  is 
  a 
  branch 
  of 
  the 
  

   Green 
  liiver 
  and 
  of 
  that 
  of 
  the 
  Colorado. 
  So 
  it 
  can 
  be 
  under- 
  

   stood 
  why 
  the 
  sea 
  emptied 
  into 
  the 
  south 
  and 
  also 
  why 
  the 
  red 
  

   sandstone 
  is 
  there 
  without 
  the 
  white 
  bacillarian 
  clay 
  upon 
  it. 
  

   For 
  the 
  same 
  phenomenon 
  is 
  present 
  in 
  Lake 
  Passaic 
  in 
  New 
  

   Jersey, 
  where 
  the 
  clayey 
  sand 
  without 
  bacillaria, 
  in 
  it 
  is 
  present 
  

   at 
  Logansville 
  and 
  Pleasant 
  Plains 
  in 
  parallel 
  thin 
  layers, 
  the 
  

   bacillarian 
  clay 
  having 
  lower 
  specific 
  gravity, 
  being 
  carried 
  down 
  

   to 
  a 
  lower 
  point 
  and 
  deposited 
  at 
  Hatfield 
  Swamp 
  when 
  the 
  ice 
  

   barrier 
  melted 
  at 
  and 
  about 
  Paterson. 
  

  

  Next 
  came 
  what 
  King 
  calls 
  the 
  Gosiate 
  Lake, 
  which 
  includes 
  

   the 
  Green 
  Piver 
  group 
  of 
  Hayden 
  and 
  the 
  Elka 
  group 
  of 
  

   King. 
  Along 
  the 
  east 
  base 
  of 
  the 
  Wahsatch 
  Mountains 
  the 
  

   rocks 
  were 
  tilted 
  up 
  to 
  14°, 
  leaving 
  the 
  Uinta 
  Piver, 
  as 
  it 
  was 
  

   in 
  the 
  Lake 
  period, 
  an 
  island. 
  The 
  rocks 
  in 
  this 
  were 
  mere 
  

   shales 
  and 
  calcareous 
  clay, 
  with 
  some 
  white 
  fine 
  limestone. 
  

   Numerous 
  fishes 
  and 
  insects 
  and 
  abundance 
  of 
  fresh 
  water 
  

   molluscs 
  of 
  the 
  genera 
  Yiviparus, 
  Goniobasis 
  and 
  Unio, 
  besides 
  

   a 
  few 
  beds 
  of 
  lignite, 
  are 
  seen. 
  

  

  Then 
  came 
  the 
  Wahsachie 
  Lake, 
  which 
  includes 
  the 
  Bridges 
  

   group 
  of 
  King 
  and 
  the 
  Uinta 
  Lake, 
  which 
  includes 
  the 
  Uinta 
  

   group 
  of 
  Emmons 
  and 
  Marsh. 
  This 
  ends 
  the 
  Eocene. 
  

   Afterwards 
  the 
  Miocene 
  was 
  laid 
  down, 
  which, 
  in 
  the 
  province 
  

   of 
  Nevada 
  and 
  Oregon 
  contains 
  the 
  Pah-Ute 
  Lake, 
  which 
  was 
  

   the 
  Truckee 
  group 
  of 
  King 
  and 
  the 
  John 
  Day 
  group 
  of 
  Marsh, 
  

   and 
  was 
  contemporaneous 
  with 
  the 
  Sioux 
  Lake, 
  which 
  in 
  the 
  

   province 
  of 
  the 
  Great 
  Plains 
  includes 
  the 
  White 
  Pivcr 
  

   group 
  of 
  Hayden. 
  The 
  Miocene 
  came 
  also 
  to 
  an 
  end 
  and 
  was 
  

   followed 
  by 
  the 
  Pliocene 
  : 
  In 
  this 
  came, 
  contemporaneous 
  with 
  

   the 
  province 
  of 
  the 
  Great 
  Basin, 
  North 
  Park 
  Lake 
  of 
  the 
  North 
  

   Park 
  group 
  of 
  Hague 
  and 
  Hayden 
  and 
  Cheyenne 
  Lake 
  of 
  the 
  

   province 
  of 
  the 
  Great 
  Plains 
  and 
  the 
  Niobrara 
  group 
  of 
  Marsh. 
  

  

  At 
  Kausoh 
  Mountains 
  in 
  Nevada 
  the 
  strata 
  were
