The same Member I Giza limestone found in Khentkawes and Kai's tombs also appears in the Sphinx enclosure. Researchers propose late pre-dynastic/early dynastic people shaped a natural limestone formation as a commanding feature visible to travelers below. Evidence of late Predynastic burials found at Giza near the Great Pyramid suggests substantial activity on the plateau before the 4th Dynasty. ⛏️
Key Facts
- Limestone strata composing tombs of Khentkawes and Kai is Member 2 Giza limestone, same as exposed in Sphinx enclosure, extends across Giza plateau
- Geological analysis identified natural escarpment running through central field influenced by local geology
- Escarpment faced south overlooking main Wadi and east-facing section present
- Southern side of Khentkawes tomb and southern/eastern sides of Kai tomb align with former natural escarpment line
- Hypothesis: late pre-dynastic or early dynastic people carved natural escarpment with palace facade decoration as statement of importance
- Palace facade decoration at Abidos royal enclosures faces vegetated Nile Valley; Giza decoration faces vegetated valleys and waterways, suggesting commanding statement to river travelers
- Copper contamination spike in sediments dated 3265-3185 BCE (late pre-dynastic) shows substantial settlement on plateau
- Colin Reader attributes majority of features to 2nd dynasty; alternative interpretation suggests pre-dynastic elite settlement at Giza
- Sphinx grotto possibly pre-dynastic rock-cut dwelling; Sphinx enclosure and first phase Sphinx temple potentially late pre-dynastic features
