A neandethal on a bike on the ice
And humans have used the dry North Sea to migrate from France to England and back during the last 800.000 years, depending on the climate state. And when there was enough ice, they could also walk to Ireland! No ferry needed. Or cycle, if they had invented the wheel.

Geology of Paris-Roubaix - When did the Hell of the North break loose?
The wind picked up the silt from these rivers and spread it around. This wind-deposited silt is known as loess, and northern France is covered by it.
Loess is a nightmare for anything on wheels, so early on, big cobbles were brought in from Belgium to pave the roads!

Well, dry, it was occupied by a tundra and a large river, that combined the Rhine, the Meuse, the Scheldt, and the Thames.
These flowed towards the Bay of Biscay. Mammoths roamed the banks, and the vast tundras south of the ice caps of Scandinavia.

OK, so we decided not do skip a GeoTdF year, but this stage is so boring that it's begging for some geo-info!
We're riding along the North Sea coast towards Dunquerque. But even as recent as 20.000 years ago, there was no coast here! During the last ice age, the Channel was dry!

Thanks a lot! We've really enjoyed the past four Tours and explained the geology of cycling races the world over and all year. Last year was a climax. This year there's a cooling down: it was all a hobby between full-time jobs, and those take precedence this year. But we might be back π.

I wish you a fantastic Tour, Ned. Thanks for your interest and support in our off-topic contributions of the last years. We'll be listening and enjoying the commentary of you, David, Peter et al, and everytime you see a rock along the parcours, know that we planted it there especially for you :D

OK, so we won't do a detailed GeoTdF this year, but we couldn't help ourselves...the geology of the Ventoux is quite clearly correlated with scenes during the climbs. For example, the famous 2016 incident that left Chris Froome running up with a broken bike - clearly geologically pre-determined.

Unfortunately, we won't make GeoTdF clips for Dutch (NOS) and UK (ITV) television this year. Our grants ran out, and science & teaching life got the better of us.
But it's not for lack of ideas. Just looked into the Ventoux. Wouldn't be a problem at all to make a 2 minute Geo-Cycling video there :D
