Dasht-e Kavir (Persian: دشت كوير‎), also known as Kavir-e Namak and the Great Salt Desert, is a large desert lying in the middle of the Iranian plateau. It is about 800km long and by 320km wide, making it the Earth’s 24th largest desert. It contains some large salt plates in a mosaic-like shape. Dasht-e Kavir’s climate is arid; it receives little rain or snow. However, the mountains that surround it provide plenty of runoff—enough to create vast seasonal lakes, marshlands and playas. Temperatures can reach 50C in summer, and the average temperature in January is 22C. Daytime and nighttime temperatures can vary by as much as 70C over the course of a year. Rain usually falls in winter.

The local scenery on the ground is as follows.
