lakes are called proglacial lakes. Meltwaters from the glacier's Lake Michigan Lobe, pent up for a time behind morainic ridges deposited at the ice sheet's margins, formed glacial Lake Chicago and drained southwestward, scouring what is today the lower Des Plaines valley.

Landscapes containing glacial lakes usually feature several other glacial landforms like drumlins, moraines, eskers, etc. With the Lake Michigan lobe absent to impede flow, drainage from the CKRV proceeded southwesterly until draining into glacial Lake Chicago near St. Joseph, Michigan.The outburst originated from a . 1 ).

The sequence of geologic events resulting in the formation the rising lake level and accompanying waves and currents scoured sediment from the margins of the lake. Only 5 to 7 miles wide, the peninsula has the feel of an island — there's water everywhere you turn, including several lakes at the center of the peninsula. Glacial Lake Algonquin (hereafter, GLA) is the name given to a sequence of extensive, proglacial lakes in the upper Great Lakes region. The lakes which we now call Superior, Michigan and Huron were part of two vast inland lakes called "Lake Duluth" and "Lake Algonquin". �y�ʁ��n�d�l.�+���f�
