I hope someone can help- we're trying to remember a site where a calcium springs solidifies things.......might be in Derbyshire or similar area but the old memory is not what it used to be.... Many thanks for any thoughts!!
well there's always the Mother Shipton's Cave Theme Park and Tea Shoppe* but that's in Yorkshire. http://www.mothershiptonscave.com/the_petrifying_well.htm No doubt there's shedloads of other less touristified sites though.
*I'm probably being unfair. I've not even been. I was just a bit disappointed by the state of Cheddar Gorge's attendant tourist tat the other day.
