Great Salt Desert, Iran

A mix of salt marshes, mudflats, wadis, steppes, and desert plateaus color the landscape of Iran’s Great Salt Desert, Dasht-e Kavir. The region covers an area of more than 77,000 square kilometers. Dramatic daily temperature swings and violent storms are the norm, and extreme heat leaves the marshes and mud grounds with large crusts of salt. Some vegetation has adapted to the hot, arid climate and to the saline soil. Some wildlife live in parts of the steppe and desert areas of the central plateau, while others are common in the mountainous areas. Human settlement is largely restricted to some oases. Landsat 7 acquired this image in 2003.
