Atacama Desert - Chile
Where the Amazon Rainforest is the most biologically diverse place on earth, Chile's Atacama Desert is the driest, in part due to its elevation at 7,500 feet. At some places in the desert, not a single drop of rain has ever been recorded. Elsewhere, the El Tatio geyser field looks eerily alien, as dozens of geysers emit steam into the dry desert air.
