probable, however, that such lakes existed on the site of what is now Ver- 

 milion Lake, Basswood Lake, and Saganaga Lake, and probably in many 

 other places. Indeed, Winchell and Grant" have reported terraced gravels 

 around Long Lake and White Iron Lake, which give clear evidence of the 

 existence of lakes at these places during Glacial time, when the water was 

 considerably higher than the present water level and which consequently 

 covered larger areas than those of the present lakes. WinchelP has recently, 

 since the above was written, given a brief description of the glacial lakes 

 which occur partially or wholly in the Vermilion district. 



According to him, Lake Annamani covered the present site of Vermil- 

 ion Lake, being 10 or 15 feet higher than it is. Lake Norwood was south 

 of the present Vermilion Lake, and covered the low flat area north of the 

 Giants range along the Embarrass River.
