Lut Desert

The Lut Desert is in Iran.

It has salt flats and sand dunes.

The ground gets very hot there. It is the hottest land on Earth.

In spring, water flows from the mountains. Then the water dries up. This leaves rocks and salt behind.

The wind makes shapes in the sand. These shapes look like ridges. There are also deep holes.

Old cities once lived here. People lived in this area a long time ago. It is a very special place.

The Lut Desert is in Iran. It sits in Kerman and Sistan-Baluchestan. It is the 33rd largest desert in the world.

The map shows where it sits in the region.

This place is very hot. It has the hottest land surface on Earth. In 2005, the ground reached 70.7°C.

This photo shows the salt flats. In spring, water flows from the mountains. Then the water dries up. This leaves behind rocks, sand, and salt.

The wind shapes the land. In the center, it makes parallel ridges and furrows. These are called yardangs.

This photo shows those shapes. The southeast has huge sand dunes. Some are among the tallest in the world.

Many people lived here long ago. One group was the Jiroft culture. There was also a city called Burnt City. Experts found eighty-seven old sites in this area. These sites are from many different times in history.

The Lut Desert is a vast and amazing place in Iran. It sits inside the provinces of Kerman and Sistan-Baluchestan. This desert is the 33rd largest in the whole world. It is part of a large group of deserts called the Afro-Asian belt. This belt stretches all the way from Mauritania to Mongolia.

The map shows where the desert sits in this big region. The desert is a large drainage basin that is both long and wide. It is the second largest desert in Iran after the Dasht-e Kavir.

Nature works in many ways to shape this land. During the spring wet season, water flows down from the Kerman mountains. This water does not stay for long. It soon dries up and leaves behind rocks, sand, and salt. The eastern part of the desert is a low plateau. This area is covered in salt flats.

The center of the desert looks very different. The wind has carved the land into parallel ridges and furrows. These shapes are called yardangs. The southeast has huge sand dunes that are among the tallest in the world.

This desert has a very long and interesting history. Around 2500 BC, a group called the Jiroft culture lived here. There was also an ancient city named Shahdad on the western edge. On the eastern side, there was a large city called Shahr-e Sukhteh. People also call it the Burnt City. This city sat on the Helmand River, which is now dry.

Today, the area is very important for people who study old things.

Scientists have found many facts about this desert. One study shows that volcanic rocks cover more than half of the surface. The Lut Desert is also famous for being extremely hot. It has the highest land surface temperature known on Earth. In 2005, the ground reached 70.7°C. In 2019, new data showed temperatures as high as 70.7°C again.

Because there are no permanent weather stations, the exact climate is still uncertain. Most experts think it gets very little rain each year.

Many different things make the Lut Desert special. It was added to the UNESCO World Heritage List on July 17, 2016. This means it is a place worth protecting for the whole world. Experts have found eighty-seven ancient sites near the desert. These sites date from the fifth millennium BC to the late Islamic era. Some of these sites belong to the Bronze Age. Learning about the Lut Desert helps us understand how wind, heat, and water change our world.

The Lut Desert is a massive desert located in Iran. It spans across the provinces of Kerman and Sistan-Baluchestan. This desert is the 33rd largest desert in the world. It is part of the Afro-Asian belt of deserts. This belt is a huge chain of deserts stretching from Mauritania to Mongolia.

The map shows how the desert fits into this larger regional context. The desert is a large drainage basin. It is both very long and very wide. It is the second largest desert in Iran, following the Dasht-e Kavir.

Natural processes shape the unique landscape of the Lut Desert. During the spring wet season, water flows down from the Kerman mountains. This water does not stay in the desert for long. It quickly evaporates or sinks into the ground. This process leaves behind a surface of rocks, sand, and salt. The eastern part of the desert is a low plateau. This area is covered by extensive salt flats.

These salt flats are located at elevations around 110 meters above sea level.

The center of the desert looks very different from the salt flats. In this area, the wind acts as a sculptor. It carves the land into parallel ridges and furrows. These geological features are known as yardangs. The center of the desert is also filled with ravines and sinkholes. To the southeast, the landscape changes again. There is a vast expanse of sand known as an erg. This area contains sand dunes that are among the tallest in the world.

Geology provides more clues about the desert's composition. One study suggests that volcanic rocks cover more than half of the surface. Scientists also observe evaporites during hot periods. Evaporites are minerals that form when water evaporates from a solution. The desert's surface is also famous for its extreme heat. It holds the record for the highest known land surface temperature on Earth.

This heat is a defining characteristic of the region.

NASA satellites have helped scientists measure this intense heat. Between 2003 and 2010, the Moderate-Resolution Imaging Spectroradiometer recorded extreme temperatures. In 2005, the land surface temperature reached 70.7°C. While the ground was that hot, the air temperature could have been different. In 2019, new MODIS data also reported a temperature of 70.7°C. Because there are no permanent weather stations, the exact climate remains uncertain. However, it likely receives less than 100 mm of precipitation every year.

The Lut Desert has a deep history of human activity. Around 2500 BC, the Jiroft culture flourished in this area. The ancient city of Shahdad was located on the western edge of the desert. On the eastern side, the city of Shahr-e Sukhteh once stood. This name means "Burnt City" in English. It covered 200 hectares and sat on the Helmand River. The river is now dry, but it once supported this large city.

Archaeologists find the Lut area very important for studying the past. A recent survey was conducted near the Kerman range and the western edges of the desert. Researchers identified eighty-seven ancient sites in this region. These sites date from the fifth millennium BC to the late Islamic era. Twenty-three of these sites belong to the Chalcolithic period and the Bronze Age. These findings show that people have interacted with this harsh environment for thousands of years.

The significance of the Lut Desert is recognized globally. On July 17, 2016, it was added to the UNESCO World Heritage List. This status highlights its unique geological and historical importance. The desert connects many different fields of study. It involves geography, geology, archaeology, and climate science. By studying the Lut Desert, we learn how wind, heat, and ancient civilizations interact in extreme environments.
