The Deadliest place on Earth? Surviving Cueva de los Cristales - The Giant Crystal Cave
By Paul Williams on Tuesday, 1 December 2009
It's 50oC and has a humidity of 100%, less than a hundred people have been inside and it's so deadly that even with respirators and suits of ice you can only survive for 20 minutes before your body starts to fail. It’s the nearest thing to visiting another planet – it’s going deep inside our own.
Just wow...
