Rhine
About 11000 years ago, the Rhine estuary was in the Strait of Dover. There remained some dry land in the southern North Sea, known as Doggerland, connecting mainland Europe to Britain. About 9000 years ago, that last divide was overtopped / dissected. Man was already resident in the area when these events happened.
