Key facts

• Preliminary satellite-based SAR scans detected a massive structure concealed beneath a 180ft-high mound of hardened sand in the extreme northwestern Giza Necropolis
• Scans show vertical shafts and passageways similar to those found beneath the original Great Sphinx
• Dense vertical lines in scan data are believed to represent solid walls of underground shafts rather than empty voids
• Filippo Biondi conducted the SAR scans using satellites 400 miles above Earth emitting electromagnetic pulses
• The scanning technology detects sound activity frequency changes when beams hit solid rock with cavities below versus solid rock alone
• The underground features appear to mirror the structure of the Great Sphinx
• Herman Junka investigated mastaba tombs in this area between 1910-1929; aerial photographs show the anomaly was not present during his excavations
• Abdul Mahin Abdul Baka worked on the western cemetery between 1914-1953; the anomaly may have been a spoil heap from his excavations
• The red and black areas in scan data indicate hollows and cavities, while blue and green areas represent less dense material
• The findings suggest a potentially larger and more extensive underground complex beneath the Giza plateau
