Scientists have discovered a long-buried branch of the Nile river that once flowed alongside more than 30 pyramids in Egypt, potentially solving the mystery of how ancient Egyptians transported the massive stone blocks to build the famous monuments.
The 40-mile-long river branch, which ran by the iconic Giza pyramid complex among other wonders, was hidden under desert and farmland for millennia, according to a study revealing the find on Thursday.
The existence of the river would explain why the 31 pyramids were built in a chain along a now inhospitable desert strip in the Nile Valley between 4,700 and 3,700 years ago.
