Comparison to other Egyptian deep structures. Known deep square shafts exist at Step Pyramid and other sites The Osiris shaft goes deep but not 648 meters Similar features found at Zawiyah, Abu Roach, and other locations

Deep square shafts are known at sites like the Step Pyramid and Zawiyat, but none approach claimed depths. The Osiris shaft at Giza is about 25 feet deep and was used as a water source in ancient times. Similar features were found at Zawiyah, Abu Roach, and other locations. Some shafts have regular depths of a couple hundred feet. The Scan Pyramids project found some voids using muography and thermal imaging, with verification remaining ongoing.
