Ancient Egyptians learned to exploit cracks in the Earth to make tomb-digging easier. Those cracks, however, allow the tombs to flood during heavy rainfall.
“We have seen evidence of seven separate flood events in four tombs so far,” said Penn State researcher Katarin A. Parizek.
Parizek had noticed that some tombs in the Valley of Kings, in Luxor, Egypt, were aligned with surface fractures that can be between 5 and 40 feet wide and up to a mile long. The fractured rock would have made for easier tomb digging, she figures. Of the 63 tombs in the area, 30 have so far been found to lie on fractures, while two lie diagonal to a trace and one is not on a fracture.
“From my observations, it seems that tomb builders may have intentionally exploited these avenues of less resistant limestone when creating tombs,” Parizek said.
