Admittedly, the images are enhanced by the false colors the satellite imagery injects, but these are stunning!
above: Great Salt Desert, Iran
Like poster paints run wild, this image reveals an eclectic montage of landscapes in Iran's largest desert, the Dasht-e Kavir, or Great Salt Desert. The word kavir is Persian for salt marsh. The almost-uninhabited region covers an area of more than 77,000 square kilometers [29,730 square miles] and is a mix of dry streambeds, desert plateaus, mudflats and salt marshes. Extreme heat, dramatic daily temperature swings, and violent storms are the norm in this inhospitable place.
