Lake Ojibway

The Agassiz and Ojibway ice reservoirs, around 7900 BC. Chr.

Lake Ojibway ice reservoir was a prehistoric lake in what is now northern Ontario and Quebec in Canada and the last of the great ice reservoirs of the last ice age . It reached its greatest extent around 8,500 years ago.

background

The Ojibway Ice Reservoir was relatively short-lived. The lake emptied into Hudson Bay in a mega- flood about 8,200 years ago, possibly due to an ice dam or a glacier run . The resulting lowering of the salt content and the associated interruption of the thermohaline circulation could be related to the so-called misox fluctuation , a relatively short-term climate change around 8,200 years ago.
