It pleases the Central European in me that the Thames and the Seine were both once tributaries of the Rhine.
@ottocrat thinking about our ancestors walking across Europe to the UK and how moving around the planet is what us humans do.
@ottocrat Or was the Rhine the eastern branch of the Thames?
It’s all about perspective
@bouriquet They’re all actually tributaries of the Neckar. #Schwaben
@ottocrat Wow that's a cool map.
I don't remember hydrogeological/fluvial conventions, but I think it would be possible to know which of the three would 'win' and be the one that throws itself in the ocean, right?
I mean, there are criteria to decide who gets to keep its name when two waterways converge, right?

@ottocrat

The difference between 8,000 BCE and 7,000 BCE kinda blows my gourd. That's a lot of land to disappear in just a thousand years β€” and a thousand years isn't a very long time. That's fast enough that your grandmother could have remembered a time when this coastal swamp was merely marshy ground; and her grandmother told her stories of when it was a flood plain, wonderful farmland, and the sea was almost a mile away.

@ottocrat RIP Doggerland. Once a huge and thriving part of the ecosystem, Doggers are now limited to small pockets of habitat in the UK. πŸ˜”
@Tattie @ottocrat Including the tribe of Doggers who moved to North America, first in New York and then to Los Angeles. By now, of course, the spelling has shifted over time to the more familiar Dodger.
@ottocrat Missing Welsh glaciers on here - no glaciers, no valleys, what would that be like?
@ottocrat how different it will all be, given what's happening with the climate. I've seen drawings of Europe reduced to an archipelago.
@ottocrat better than that there was a direct high speed rail connection from Berwick-upon-Tweed to er...Groningen. Before a meteorite killed off the railways
My daughter has sent me a picture from #Scotland
@SeanJones Why was there an opening in the clouds directly above the cow? #whathappenednext?
