Desert Archaeology

Deserts may look empty, but they are full of hidden history. The dry conditions in deserts preserve ancient buildings, tools, and even mummies. Archaeologists explore deserts to find clues about people who lived there long ago. Some of the world's greatest discoveries have been made in desert sands.

Why Deserts Preserve History

Deserts are very dry, which means things do not rot as quickly as in wet places. Ancient buildings can last for thousands of years in desert sand. Even delicate items like cloth and paper have been found in good condition. Sand can also bury and protect sites from damage over many centuries.

Famous Desert Discoveries

The pyramids of Egypt are the most famous desert archaeology sites. In the Sahara, scientists have found ancient rock art showing a time when the desert was green. The lost city of Petra in Jordan was carved into desert cliffs. In the American Southwest, ancient cliff dwellings show where people lived hundreds of years ago.

Fun Facts

• The ancient city of Petra in Jordan was lost to the outside world for hundreds of years.
• Rock art in the Sahara shows hippos and crocodiles, proving the desert was once wet.
• The Nazca Lines in Peru are giant desert drawings that can only be seen from the air.

Did You Know?

The dry desert air of Egypt preserved mummies so well that scientists can still study their hair, skin, and bones thousands of years later.
