Loot Plain, Zahedan
The plain of Loot is the largest hollow or pit in the plateau of Iran and a part of which is located between Sistan Va Baluchestan. This plain is one of the hottest and driest in the world with a minimum trace of water. To the west of this plain, is another area of wilderness called Namakzar, which is impenetrable in the rainy seasons. The eastern half of the plain is covered by moving sands, but a part of its southern sector is penetrable.
Due to the hot sun and strong winds, heavy masses of sand move to the south and the southeast, forming a chain of sandy hillocks.
