Found at last: long-lost branch of the Nile that ran by the pyramids

Geological survey reveals the remains of a major waterway that ancient Egyptian builders could have used to transport materials.

By Freda Kreier

Stretching beneath the ground near the Giza pyramid complex in Egypt lie the remains of an ancient branch of the Nile River that might once have helped ancient Egyptians to build their monuments.

The highest concentration of pyramids in Egypt can be found in a stretch of desert between Giza and the village of Lisht. These sites are now several dozens of kilometres away from the Nile River. But Egyptologists have long suspected that the Nile might once have been closer to that stretch than it is today.

Satellite images and geological data now confirm that a tributary of the Nile — which researchers have named the Ahramat Branch — used to run near many of the major sites in the region several thousand years ago. The discovery, reported on 16 May in Communications Earth and Environment1, could help to explain why ancient Egyptians chose this area to build the pyramids (See ‘Ancient river’).

Abstract

The largest pyramid field in Egypt is clustered along a narrow desert strip, yet no convincing explanation as to why these pyramids are concentrated in this specific locality has been given so far. Here we use radar satellite imagery, in conjunction with geophysical data and deep soil coring, to investigate the subsurface structure and sedimentology in the Nile Valley next to these pyramids. We identify segments of a major extinct Nile branch, which we name The Ahramat Branch, running at the foothills of the Western Desert Plateau, where the majority of the pyramids lie. Many of the pyramids, dating to the Old and Middle Kingdoms, have causeways that lead to the branch and terminate with Valley Temples which may have acted as river harbors along it in the past. We suggest that The Ahramat Branch played a role in the monuments’ construction and that it was simultaneously active and used as a transportation waterway for workmen and building materials to the pyramids’ sites.

... and allow robbers to work in solitude? And in 7,000 years a river moves a lot without a corps of engineers building dikes and clearing channels.

"Data analysis indicates that this lateral distributary channel lies between 2.5 and 10.25?km west from the modern Nile River", and you can add on a km or two to the pyramids themselves. I wonder if the writer tried to decide between "several km" and "up to a dozen km" and ended up with the misleading "several dozen".
