5. The Kaluts, Iran
The Kaluts are a series of eroded towers and walls sticking out of the desert (the Dasht-e Lut) in the province of Kerman, and running for a distance of over 120 miles north to south. The Kaluts are the hottest place and the lowest area in Iran, which stands at 56 m above sea level where the temperature reaches 149F (65C) in the shade! These formations have been created over the millennia by soil erosion water, and wind.
