What modern technology revealed inside the King's Chamber! In the 1980s, microgravimetry and electromagnetic surveys were carried out on the floor. Both methods detected a large central anomaly matching the known excavation pit, plus smaller anomalies in the northeastern and southwestern corners. Researchers believe these reflect rubble and quartz sand fill used by the original builders. Pretty cool non-invasive archaeology! 🔬

Key facts

  • In the 1980s, the King's Chamber floor underwent microgravimetry and electromagnetic surveys
  • Microgravimetry located small negative anomalies in the northeastern, southeastern, and southwestern corners of the floor
  • Electromagnetic survey showed anomalies below the floor in the southwestern and northeastern corners, but nothing in the southeastern corner
  • Both surveys detected a large anomaly in the center of the room corresponding to the known excavation pit
  • The anomalies likely reflect filler materials such as rubble and quartz sand used by pyramid builders to fill construction cavities
