There's a lot of treacle on the 'Net: the Treacle Mine Hotel, Treacle Mine Rag, the Ditchford Treacle Mine -- and those are just the serious ones!

Mind you, it's made me think of something I'd forgotten from my childhood. Where I grew up in the 50s, there had been several 19th C ironworks: there was coal and ironstone inthe ground; and the whole place for (literally) miles around was covered in furnace slag. This was a greyish-white flint-like substance: very sharp-edged, and not much fun to play on. Some of it still had a lot of iron in it, and was a rusty brown in colour. In one place, in the "Badlands", as we called it, there was a Great Wonder of Nature: the Vimto Pool. (For any non-Brits: Vimto is the English equivalent of Coke or Pepsi.) The water had leached out so much iron oxide, it looked like Vimto, albeit pretty flat; it didn't taste much like it, though!
