The shells are of species of gastropods and pelecypods whose living representatives inhabit water 1–15 feet deep.The level of this low-water stage is placed at 350 feet below the present lake surface, and the time of the low-water stage at post-Algonquin and pre-Nipissing. This low-level Lake Michigan drained through the Straits of Mackinac into a low-level Lake Huron, as was proposed by G. M. Stanley in 1936.Features of the low-water stage in the Lake Michigan basin are named Southern Lake Chippewa, Grand Haven River, Lake Chippewa, and Mackinac River. The low-water stage in the Lake Huron basin is named Lake Stanley. This content is PDF only. Please click on the PDF icon to access.
