KANDIYOHI AND MEEKER COUNTIES, isss. WARREN UPHAM. 



one coming from the southwest and one from the northwest and uniting in the 

 vicinity of lake Andrew. The location of these streams in Kandiyohi and Pope 

 counties, where they flowed at first on the ice and then in ice-walled valleys, is indi- 

 cated by the gravelly kames, or long " hogsbacks," which they formed. One extends 

 from Mamre through Dovre and then northward to unite, with more or less confusion 

 in its contour, with the other at the east side of lake Andrew. The other line of long 

 gravel ridges or kames is that which extends northwestward and to the "blue 

 mounds" in Pope county. The latter apparently extends much further, and plainly 

 indicates a long and turbulent river, whose course was frequently disturbed by the 

 shifting of the glacier and by the deposits of drift which it brought forward, but 

 whose course was, in the main, nearly constant along the line of these kames. 



This view of these gravel ridges is slightly different from that presented by 

 Mr. Upham in his report on these counties, and on Pope county, who considered them 

 as deposited by ice rather than water. The writer has personally examined only 

 the "blue mounds" in Pope county (Thirteenth Annual Report, page 18), and he 

 found this ridge there composed chiefly of gravel and sand, with boulders. This 

 question should receive further investigation. N. H. w.
