Iran is situated in a high-altitude plateau surrounded by connected ranges of mountains. The well-known deserts of Iran are at two major regions: 1) Dasht-e-Kavir, and 2) Kavir-e-Lut. They are both some of the most arid and maybe hottest areas of their kinds in the world. Kavir-e-Lut is the largest pit inside the Iranian plateau and probably one of the largest ones in the world. Kavir-e-Lut is a pit formed by broken layers of the earth.
