The lake was essentially an enlargement of the present [[Lake Ontario]] that formed because the [[St. Lawrence River]] downstream from the lake was blocked by the ice sheet near the present [[Thousand Islands]]. The level of the lake was approximately 30 m (~100 ft) above the present level of Lake Ontario.<ref name=Larson>{{cite journal |title=Review: Origin and Evolution of the Great Lakes |last1=Larson |first1=Grahame |last2=Schaetzl |first2=Randall<!--authorlinks [[Grahame Larson]], [[Randall Schaetzl]]--> |journal=J.

The lake drained to the southeast, through a channel passing near present day [[Rome, New York]]. The [[Rome Sand Plains]] has several sand ridges that geologists think were formed at this time. The channel then followed the valley of the [[Mohawk River]] to the [[Hudson River]].<ref name=Larson />

Another ancient shoreline exists between 2–4 km offshore of Toronto. It is known as the ''[[Toronto Scarp]]'' and formed the shore of [[Lake Warren|Glacial Lake Warren]] or [[Admiralty Lake]]. From Bluffer's Park in Scarborough to just west of Hanlan's Point is an underwater bluff.<ref>{{Cite web |title=Nearshore Geology |publisher=City of Toronto TRC |date=n.d. |url=http://www.aquatichabitat.ca/nearshore_geology.shtml |access-date=26 December 2009 |url-status=dead |archive-url=https://web.archive.org/web/20120226233631/http://www.aquatichabitat.ca/nearshore_geology.shtml |archive-date=26 February 2012 }}</ref>
In [[Hamilton, Ontario]] the [[Burlington_Heights_(Ontario)|Burlington Heights]] represents a sand and gravel bar formed across the mouth of [[Cootes Paradise]], at the western end of Glacial Lake Iroquois.
