The Carvern: Undeground Car Graveyard Somewhere in a flint mine is an underground lake. Cars had been dumped and pushed into it through a hole above creating a large scrapheap. It is said that these are all road traffic accidents, However I am not 100% sure on that. A group of eight of us met nearby and ventured in after a reasonable decent we had a brief walk to the lake the sight we were greeted with was amazing. This was such a fun day. Great teamwork in getting our gear and ourselves up and down the rock face and taking it in turns to paddle back and forth in dinghies. Even a rescue mission at the end when one dinghy got a puncture.
