Now, they may have found the answer in a long-lost, ancient branch of the River Nile that once flowed alongside more than 30 pyramids in the northeastern corner of Africa. A team from the University of North Carolina Wilmington used radar satellite imagery, historical maps, geophysical surveys, and sediment coring (a technique used by archaeologists to recover evidence from samples) to map the river branch, as per the BBC.

The river branch, named the Ahramat branch, with “ahramat” meaning pyramids in Arabic, was roughly 64km (39 miles) long and between 200-700m (656-2,296 ft) wide. It bordered 31 pyramids (including the Great Pyramid of Giza, the largest Egyptian pyramid and oldest of the Seven Wonders of the Ancient World), which were built between 4,700 and 3,700 years ago.

Onstine added: “The discovery reminded me about the intimate connection between geography, climate, environment and human behavior.”
