Beneath the blazing Bolivian sun lies a land of extremes, ranging from desolate highland plateaus to dormant volcanic landscapes. But the true wonder of this astonishing land is Salar de Uyuni--an endless salt flat so blindingly white it can be seen from outer space.

Iceland is the world's largest volcanic island, a fact that's makes it a breathtaking, but deadly, geological marvel. Take a journey along a ridge that divides continents, follow endless fields of solidified lava, and witness the rare and striking spectacle of a volcano erupting under a glacier.
