Geological Society of America's journal Geology (April) printed an article on these giant crystals.  Abstract is available at http://www.gsajournals.org/perlserv/?request=get-abstract&doi=10.1130%2FG23393A.1
According to the authors, these crystals could only form under very specific conditions- they had to grow in a saturated solution at the gypsum-anhydrite phase transition, which is slightly below 58 degrees C.  If either the temperature or the level of saturation vary much over time, new nucleation (new crystals) form instead of the immense crystals found.  Estimated time to form these crystals ranges from thousands to millions of years.

It WAS the 4th Episode.

The American version was narrated by Sigourney Weaver !!!...How dare they rub out David Attenborough !!

Here's a wiki link to the cave system with some links at the bottom of the page !!

Carlsbad Caverns National Park, New Mexico. That is where my moms pictures were taken of the cave I spoke of! I will have to look further and find them!

there are some really amazing pictures and great footage of evaporite deposits in awe-insipiring caves ! has anyone seen the Ian Stewart programmes of planet earth ? theyve been on BBC1 english television ? They were great programmes and the last episode was on tuesday i think. these caves are millions of years old in the Mediterranean sea and people arent allowed inside them because the condensation from their bodies will slowly start to dissolve the deposits of gypsum these crystals were metres long and totally amazing !
