Khafre pyramid mortuary temple shows 2 feet of limestone erosion

The pyramid of Khafre had its outer limestone casing systematically removed, with only the upper quarter of Tura limestone casing remaining. The granite casing at the bottom course was also stripped, exposing the limestone core to differential erosion and honeycomb weathering patterns. Contemporary accounts and archaeological evidence document blocks that fell within the historical record, showing weathering rates. Standing walls display centuries of exposure since the casing removal. Comparison between recently fallen blocks and long-exposed surfaces reveals differential erosion patterns, though precise dating of the casing removal varies. Notably, alternative chronology proponents point to discrepancies in weathering rates between different structures on the Giza plateau as evidence for reassessing conventional dating.
