Because the crystals resemble giant icicles, the picture suggests it must be very cold inside the Cave of Crystals - but appearances can be deceptive. In fact, the temperature is a sweltering 112F, with a humidity of 90-100 per cent.
This is why cavers wear protective suits and carry backpacks of ice-cooled air.
