Until you notice the orange-suited men clambering around, it's hard to grasp the extraordinary scale of this underground crystal forest.
Nearly 1,000 ft below the Chihuahua Desert in Mexico, this cave was discovered by two brothers drilling in the Naica lead and silver mine. It is an eerie sight.

Up to 170 giant, luminous obelisks - the biggest is 37.4ft long and the equivalent height of six men - jut across the grotto like tangled pillars of light; and the damp rock of their walls is covered with yet more flawless clusters of blade-sharp crystal. ...
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.
