Revision of Moraines North of Lake Superior, by A. H. 

 Elftman. 



Glacial Lakes of St. Louis and Nemadji, by Prof. N. H. 

 Winchell. 



[abstract.] 



At the extreme western end of Lake Superior are beaches showing 

 that that lake has been at higher levels and that it left distinct traces 

 of itself. The first lake formed by the damming of the St. Louis river 

 by the ice of the Lake Superior glacial lobe was a small lake wholly 

 confined within Carlton county, about 523 feet higher than the present 

 level of Lake Superior. It had its outlet to the southward, uniting 

 with the waters of the St. Croix and thence reached the Mississippi 

 river. Lake Nemadji was due to the same agent and was the first lake 

 water, the residum of which remains to the present as a constituent 

 part of the area of Lake Superior. This lake covered, in general, the 

 valley of the Nemadji river and its level was 468 feet above the present 

 level of Lake Superior. Its outlet was in sees. 16 and 17, T. 46, R. 18. 



These glacial lakes are describel in Vol. 4 of the Final Report of 

 the Geological Survey of Minnesota, pp. 18-21. 



The eastern limit of Glacial Lake Agassiz, by U. S. Grant. 



[abstract.] 



The waters of Lake Agassiz are thought to have extended eastward 

 so as to include the area now occupied by Rainy Lake. From the fact 

 that the lacustrine deposits of the former lake extend eastward practic- 

 ally only to the western edge of the latter lake, it seems probable that 

 the evtreme altitude of Lake Agassiz was in this area but a few feet
