jpc Posted January 29, 2020 Share Posted January 29, 2020 Hey folks... Here is a question that came up today at work. Did anyone find fossils in all the rock that was brought to the surface when the Chunnel was being built? Did any of you folks in southern UK and northern France get to have a look at these rocks? Thanks 2 Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted January 29, 2020 Share Posted January 29, 2020 I remember talking to a worker who said he'd found lots of 'shell' fossils. Never got to see any myself and didn't hear of anything important being found. https://www.geolsoc.org.uk/GeositesChannelTunnel 5 Life's Good! Tortoise Friend.

Pemphix Posted January 29, 2020 Share Posted January 29, 2020 As far as documented, they used the sediment from the tunnel on the british side to win some land by throwing into the sea. Result: promontory Samphire Hoe, which is property of Eurotunnel Ltd: https://en.wikipedia.org/wiki/Samphire_Hoe_Country_Park https://de.wikipedia.org/wiki/Eurotunnel https://en.wikipedia.org/wiki/Channel_Tunnel That may explain why there are no documented finds... Furthermore, most of the material would have been destroyed due to the tunneling-boremachine.... And at least, the sediments can be easily collected on the shores of the UK: https://ukfossils.co.uk/tag/gault-clay/ Nevertheless some finds were reported (rescue excavation in pleistocene sediments of scientific interest): https://www.geolsoc.org.uk/GeositesChannelTunnel 4 Link to comment Share on other sites More sharing options...
jpc Posted January 29, 2020 Author Share Posted January 29, 2020 Thanks, folks. The same guy who asked this also thought it would be great to run a slightly long marathon in the chunnel... slightly longer than 26.2 miles. Link to comment Share on other sites More sharing options...

I love to run long distance but I need sky above me! That would be like going through the underground passages in the Lord of the Rings. Link to comment Share on other sites More sharing options...
Coco Posted January 29, 2020 Share Posted January 29, 2020 Hi, I can’t imagine racing in a tunnel entirely ! I need to breathe and see the scenery. I do almost all nature races and practically no road races.

Wrangellian Posted January 30, 2020 Share Posted January 30, 2020 Is the Chunnel well-ventilated or clogged with exhaust? Link to comment Share on other sites More sharing options...

I had the same question concerning running from England to France. Tunnels are generally vented,so I iamgine it is also. Link to comment Share on other sites More sharing options...
Wrangellian Posted January 30, 2020 Share Posted January 30, 2020 I remember going thru the one between France and Italy in 2011 (the one that goes under Mont Blanc), and it was noticeably smoggy. I don't know to what extent it was ventilated, other than those fans they have at regular points along the ceiling, but it was not very effective! I've never been thru the Chunnel but it's hard to imagine something that long and mostly underwater being ventilated better than that, but I've been surprised before...

Bobby Rico Posted January 30, 2020 Share Posted January 30, 2020 You not a loud to walk or drive though the tunnel. All commuting is done on trains. Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted January 30, 2020 Share Posted January 30, 2020 Big fans and the trains themselves operating as pistons to move the air seems to do the trick. I have seen videos of workers walking through the access tunnel, without masks and they seem to be okay. https://www.aivc.org/sites/default/files/airbase_ 1 Life's Good! Tortoise Friend.

It seems that at least a handful of people have done it even though it is not allowed. They enter at Calais and then hang on for dear life when the trains go by at high speed.

Unfortunately, its in a salt mine with no fossil record apparent. https://runsignup.com/Race/KS/Hutchinson/MineRun5K Link to comment Share on other sites More sharing options...
Coco Posted January 30, 2020 Share Posted January 30, 2020 Hi, Interesting. I guess you have to wash your shoes after the race. There’s no exhaust. It must be nice to do. $55 to run 5 km ? Here about € 5... But maybe it’s because it’s underground.
