Most of the Tura limestone casing was removed from Khafre's pyramid, leaving its limestone core exposed; casing stones remain over the upper third. The bottom casing course was pink granite, not a separate granite casing on the mortuary temple. The video points to a block fall within the historical record and compares its pristine limestone face with long-exposed masonry, estimating about 2 feet of erosion and 50-100 years of weathering on the newer surface. It argues that uneven erosion among Old Kingdom-dated Giza structures warrants revisiting conventional dating.
Video argues Khafre pyramid core shows about 2 feet of erosion

Key facts
- Khafre's pyramid retains Tura limestone casing over roughly its upper third, not just the upper quarter.
- The bottom casing course was pink granite; it was not a separate granite casing layer stripped from the mortuary temple.
- The video says a recorded block fall exposed a pristine limestone face and estimates about 2 feet of erosion and 50-100 years of weathering on the newer surface; the supplied sources do not independently verify these figures.
- The video argues that differing weathering among Old Kingdom-dated Giza structures warrants reconsidering conventional chronology.
