LAKE COUNTY, 1899. N. H. WlNCHELL. 



lake was probably only a lake-like expansion of an important drainage course, at 

 first along the southern border of the continental ice, similar in outline to the present 

 connected lakes which are formed by the Kawishiwi river from lake Isabella to 

 Garden lake. Thus the upper Kawishiwi river, gathering its waters first into lake 

 Elftman, escaped into lake Dunka, and thence over a low divide passed into lake 

 Norwood. By this stream was excavated the deep channel through the Mesabi 

 moraine at the Embarras lakes. The stream then entered lake Upham, and further 

 south lake St. Louis of Carlton county, and discharged into the Mississippi by way 

 of the Moose and Kettle rivers. This must have been the course of glacial drainage 

 from the interlobate area between the continental, or northern, ice margin and that 

 of the Lake Superior ice-lobe, as the two lobes successively uncovered greater and 

 greater areas toward the northeast, the areas first uncovered being continually the 

 highest, and the medial moraine left by them being the Itasca and Mesabi moraines. 

 There remains yet much to be done to work out the details of this grand retreat. 



This region is naturally one of forest, mainly coniferous, but fires have swept 

 off the primeval forest and lumbermen have taken much of the pine that remained.
