Amazing crystals in South American cave

Naica Cave was only discovered recently when miners broke through into it. It's full of enormous crystals of gypsum and features in tonight's BBC programme How the Earth Made us presented by Iain Stewart.

To give you an idea of why it's an incredible place, that crystal running nearly horizontally in from the lower left to the middle of the picture is big enough for Stewart to walk along! It must be nearly half a metre thick!

So I recommend you watch the programme tonight, but if you just want to get a flavour, visit the BBC website which has a short video clip.
