 sediments. Bull. Geol. Soc. Am., 

 Vol. 66, pp. 957-968. 

 From the nature of core samples 

 from various depths it is concluded 

 that in a period identified as post- 

 Algonquin and pre-Nipissing the level 

 of Lake Michigan was 350 feet below 

 the present stage. This low -level 

 "Lake Chippewa" drained northward 

 through the Straits of Mackinac into 

 a low -level Lake Huron, termed 

 "Lake Stanley" .
