Lake Ojibway

Common card · No. 492962

Lake Ojibway was a prehistoric lake in what is now northern Ontario and Quebec. Ojibway was the last of the great proglacial lakes of the last ice age. The lake was named in 1909 by Canadian geologist Arthur Philemon Coleman after the Ojibway who occupied the proposed location of the lake. Comparable in size to Lake Agassiz (to which it was likely linked), and north of the Great Lakes, it was at its greatest extent c. 8,500 years BP. The former lakebed forms the modern Clay Belt, an area of fertile land. Lake Ojibway was relatively short-lived. The lake likely drained approximately 8,200 years BP. One hypothesis is that a weakening ice dam separating it from Hudson Bay broke, as the lake was roughly 250 m (820 ft) above sea level. Recent studies assert Lake Ojibway drained in two separate events and through a combination of ice dam breach and subglacial flooding.
