  Agassiz. 
  The 
  subject 
  is 
  a 
  little 
  apart 
  from 
  

   the 
  present 
  paper 
  and 
  I 
  can 
  discuss 
  it 
  no 
  farther 
  than 
  to 
  point 
  

   out 
  the 
  probable 
  continuity 
  of 
  the 
  Chippewa 
  beach 
  and 
  that 
  

   known 
  as 
  the 
  Herman 
  beach 
  of 
  glacial 
  Lake 
  Agassiz. 
  From 
  

   D 
  ninth 
  to 
  L'Anse 
  the 
  Chippewa 
  beach 
  rises 
  about 
  56 
  feet 
  in 
  

   172 
  miles, 
  or 
  about 
  four 
  inches 
  per 
  mile.* 
  Mr. 
  Upham 
  shows 
  

   the 
  highest 
  beach 
  of 
  " 
  Glacial 
  Lake 
  Agassiz 
  " 
  reaching 
  up 
  to 
  

   Lake 
  Naquauqnon 
  at 
  the 
  west 
  end 
  of 
  Hunter's 
  Island 
  on 
  the 
  

   international 
  boundary. 
  f 
  This 
  lake 
  is 
  1186 
  feet 
  above 
  sea 
  level 
  

   and 
  is 
  about 
  140 
  miles 
  west 
  and 
  25 
  miles 
  north 
  from 
  Mt. 
  

   Josephine 
  and 
  120 
  miles 
  straight 
  north 
  of 
  Dnluth. 
  On 
  the 
  

   best 
  present 
  data 
  the 
  Chippewa 
  plane 
  produced 
  from 
  these 
  

   places 
  strikes 
  about 
  20 
  feet 
  below 
  its 
  level. 
  This 
  lake 
  is 
  about 
  

   75 
  miles 
  from 
  the 
  nearest 
  point 
  on 
  the 
  Superior 
  shore. 
  

  

  From 
  Mt. 
  Josephine 
  to 
  the 
  east 
  side 
  of 
  Beltrami 
  Island 
  is 
  

   about 
  250 
  miles 
  a 
  little 
  north 
  of 
  west. 
  The 
  highest 
  beach 
  at 
  

   Mt. 
  Josephine 
  is 
  1207 
  feet 
  above 
  sea 
  level 
  and 
  that 
  on 
  Beltrami 
  

   Island 
  1215 
  feet, 
  and 
  Lake 
  Naquauquon 
  lies 
  almost 
  directly 
  

   between. 
  The 
  Chippewa 
  plane 
  carried 
  westward 
  strikes 
  50 
  

   to 
  100 
  feet 
  below 
  the 
  Herman 
  beach 
  in 
  the 
  valley 
  of 
  the 
  Bed 
  

   Biver 
  of 
  the 
  North. 
  

  

  The 
  Herman 
  beach 
  rises 
  from 
  1045 
  feet 
  at 
  Lake 
  Traverse 
  to 
  

   nearly 
  1170 
  feet 
  at 
  Maple 
  Lake 
  and 
  1215 
  feet 
  on 
  Beltrami 
  

   Island, 
  and 
  to 
  something 
  more 
  than 
  1186 
  feet 
  at 
  the 
  west 
  end 
  

   of 
  Hunter's 
  Island 
  ; 
  on 
  the 
  west 
  side 
  to 
  1226 
  feet 
  at 
  the 
  inter- 
  

   national 
  boundary 
  in 
  Dakota 
  and 
  to 
  1460 
  feet 
  near 
  the 
  north- 
  

   west 
  corner 
  of 
  Manitoba. 
  The 
  altitude 
  of 
  Bainy 
  Lake 
  above 
  

   sea 
  level 
  is 
  1117 
  feet 
  and 
  of 
  the 
  Lake 
  of 
  the 
  Woods 
  1060 
  feet. 
  

   About 
  200 
  miles 
  northeast 
  of 
  the 
  latter 
  is 
  the 
  Height 
  of 
  Land 
  

   and 
  the 
  divide 
  between 
  Lac 
  Seul 
  and 
  Lake 
  St. 
  Joseph. 
  The 
  

   altitude 
  of 
  the 
  former 
  is 
  1232 
  feet 
  and 
  of 
  the 
  latter 
  1172 
  feet. 
  

   Lake 
  Nipigon 
  is 
  915 
  feet 
  above 
  the 
  sea. 
  From 
  this 
  last 
  lake 
  

   it 
  is 
  only 
  about 
  50 
  miles 
  east 
  to 
  Kenogami 
  Lake 
  and 
  the 
  pass 
  

   at 
  1102 
  feet. 
  The 
  Herman 
  beach 
  in 
  Minnesota, 
  Dakota 
  and 
  

   Manitoba 
  rises 
  steadily 
  northward. 
  The 
  divide 
  between 
  Lac 
  

   Seul 
  and 
  Lake 
  St. 
  Joseph 
  is 
  about 
  150 
  miles 
  north 
  and 
  the 
  

   same 
  distance 
  east 
  from 
  Beltrami 
  Island 
  where 
  the 
  beach 
  is 
  

  

  * 
  Its 
  plane 
  produced 
  passes 
  about 
  60 
  feet 
  over 
  the 
  pass 
  at 
  Upper 
  St. 
  Croix 
  

   Lake, 
  which 
  is 
  468 
  feet 
  above 
  Lake 
  Superior. 
  This 
  suggests 
  that 
  the 
  waters 
  that 
  

   made 
  the 
  Chippewa 
  beach 
  were 
  those 
  of 
  a 
  lake 
  with 
  its 
  outlet 
  at 
  this 
  pass. 
  No 
  

   doubt 
  there 
  was 
  an 
  ice-dammed 
  lake 
  in 
  the 
  western 
  part 
  of 
  the 
  Superior 
  basin 
  

   during 
  the 
  glacial 
  recession. 
  But 
  it 
  does 
  not 
  follow 
  that 
  the 
  highest 
  beach 
  found 
  

   there 
  to-day 
  was 
  made 
  by 
  that 
  lake. 
  It 
  seem^ 
  more 
  probable 
  that 
  it 
  was 
  made 
  

   by 
  the 
  waters 
  of 
  the 
  later 
  Warren 
  Gulf. 
  The 
  apparent 
  continuity 
  of 
  this 
  beach 
  

   with 
  the 
  rest 
  of 
  the 
  highest 
  beach 
  eastward 
  to 
  North 
  Bay 
  makes 
  marine 
  origin 
  

   more 
  plausible. 
  The 
  marine 
  invasion 
  probably 
  obliterated 
  the 
  remains 
  of 
  the 
  

   glacial 
  lake. 
  The 
  same 
  thing 
  probably 
  occurred 
  in 
  the 
  Ontario 
  and 
  Champlain 
  

   basins 
  and 
  possibly 
  also 
  in 
  the 
  Winnipeg 
  basin. 
  In 
  the 
  last, 
  however, 
  there 
  may 
  

   have 
  been 
  only 
  a 
  great 
  glacial 
  river 
  without 
  any 
  lake.
