The desert known for its salt flats and very high temperatures during the day is the Dasht-e Kavir, or the Great Salt Desert, located in Iran. This vast desert is characterized by large expanses of salt flats, challenging conditions, and extreme temperatures, often exceeding 50 degrees Celsius. The unique geology and climate contribute to distinctive ecosystems, where resilient flora and fauna can adapt to harsh conditions. The Dasht-e Kavir has historical significance and is also a focus for scientific research, particularly regarding desertification and climate change.
