The Valley Temple and Sphinx enclosure limestone show major erosion from water exposure, while 4th dynasty (~2700 BC) Western Cemetery structures in identical limestone remain pristine nearby. Some erosion estimates run 60,000-100,000 years — predating Old Kingdom dating entirely. Plus a giant erratic boulder moved by catastrophic forces now has a town built on it! 💧

Key facts
- Valley Temple and Sphinx enclosure limestone show significant erosion from prolonged water/rainfall exposure
- Western Cemetery (4th dynasty, ~2700 BC) and south causeway limestone structures in same material remain pristine
- Erosional patterns span multiple stone blocks, indicating erosion occurred after construction
- Some erosion estimates suggest 60,000-100,000 years of exposure, predating standard Old Kingdom dating
- Giant erratic boulder moved by catastrophic forces, now a town is built on top of it
