Scientists find buried branch of the Nile that may have carried pyramids’ stones

Discovery of the branch, which ran alongside 31 pyramids, could solve mystery of blocks' transportation

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 monuments.

The 40-mile-long (64km) river branch, which ran by the Giza pyramid complex among other wonders, was hidden under desert and farmland for millennia, according to a study revealing the find on Thursday.
