Giza Erosion Suggests Much Older Timeline. Limestone erosion rates studied: 2 feet takes 12,000-122,000 years in normal weathering Army Corps of Engineers study: 1,200 years for 2 feet in river environment Highly eroded megalithic structures vs. lesser-eroded nearby structures attributed to same period
Limestone erosion studies cite varying rates depending on environmental conditions. Alternative chronology proponents point to differential weathering patterns on ancient Egyptian structures. Fringe erosion dating hypotheses have been rejected by mainstream archaeologists and Egyptologists.
Key Facts
- Limestone erosion rates studied: 2 feet takes 12,000-122,000 years in normal weathering
- Army Corps of Engineers study: 1,200 years for 2 feet in river environment
- Highly eroded megalithic structures vs. lesser-eroded nearby structures attributed to same period
- Structures with granite casing show more erosion than without
- Major erosion difference between supposedly contemporaneous structures
