alt Hacker NewsThe great flood myths across the world are quite possibly ancestral memories of this kind of flood on a continental scale. Retreating ice age glaciers would make lakes the size of states held at bay by an impromptu dam of various kinds of debris (or more glacier) which then would break dumping great lake amounts of water hundreds of miles into the ocean within days. This kind of thing probably happened in lots of places.

It is supposed that such an event happened, when the land between continental Europe and England got flooded. This was as well during a warmer period when glacier melted. And there was human population on that land.

You just pushed me into a rabbit hole called the Zanclean megaflood.
The Missoula Floods in the northwestern US were a similar sort of event, though I'm not sure how the scale compares.
