Giza Plateau — Sphinx Enclosure / Subterranean Chamber
Sphinx Water Erosion Evidence Implies Pre-Dynastic Subterranean Construction
Full Description
erosion patterns on the Sphinx enclosure walls requiring thousands
of years of heavy precipitation — consistent with the African
Humid Period (11,000-5,000 years ago) but not with the arid
conditions of the Old Kingdom (2686-2160 BCE). Schoch dates the
Sphinx core body to approximately 10,000 BCE. The Sphinx was
carved FROM the bedrock — the same Mokattam limestone bedrock
that the Subterranean Chamber is carved INTO. If the bedrock was
being worked at the surface (Sphinx quarry) during the AHP, the
subterranean structures may have been excavated during the same
period. This would mean the Subterranean Chamber, Descending
Passage, and possibly the Ascending Passage were built during
the wettest period in 100,000 years — when the water table was
at its highest and the hydraulic system would have maximum power.
The Old Kingdom pharaohs (Khufu, Khafre, Menkaure) may have
inherited a functioning underground acoustic engine and added
the above-ground pyramid superstructure to an existing device.
This remains controversial — mainstream Egyptology dates all
structures to the Old Kingdom.

Water Erosion on the Sphinx — Implications
Geologist Robert Schoch (Boston University) argued in 1991 that the erosion patterns on the Great Sphinx and its enclosure walls are characteristic of prolonged rainfall, not wind and sand erosion. The vertical and rounded erosion profiles match precipitation-induced weathering. The Sahara has been arid since approximately 5000 BCE, meaning the Sphinx would need to predate this period by centuries...
The Hall of Records
Multiple traditions describe a hidden "Hall of Records" beneath the Sphinx or the Giza plateau containing the accumulated wisdom of an antediluvian civilization. Edgar Cayce (1877-1945) predicted the Hall would be found between the Sphinx and the Nile before the end of the 20th century. Arab historians including Al-Maqrizi described underground chambers filled with manuscripts of science and astro...
The Osiris Shaft: Three Levels Deep to the Primordial Waters
THE DEEPEST CONSTRUCTED FEATURE AT GIZA Beneath the causeway connecting the Pyramid of Khafre to the Sphinx Temple, a vertical shaft descends through three distinct levels to a depth of approximately 30 meters (98 feet) below the Giza Plateau surface. THE THREE LEVELS: LEVEL 1 (depth ~10m): A small rectangular chamber with niches cut into the walls. A shaft in the floor leads down to Level 2. ...
The Unmapped Underground: What GPR and Seismic Surveys Reveal Beneath Giza
WHAT LIES BENEATH THE GIZA PLATEAU — AND WHY WE DON'T KNOW Multiple ground-penetrating radar (GPR), seismic tomography, and electrical resistivity surveys have been conducted beneath the Giza Plateau. Each has revealed anomalies suggesting constructed features that remain unexcavated. KEY SURVEYS AND FINDINGS: 1. DOBECKI & SCHOCH (1991): Ground-penetrating radar beneath the Sphinx revealed a...
The Mokattam Formation: A Single Limestone Slab Beneath All Three Pyramids
GEOLOGICAL FOUNDATION OF THE GIZA PLATEAU The entire Giza Plateau is composed of a single continuous geological unit: the Mokattam Formation — Middle Eocene nummulitic marine limestone approximately 40 million years old. This unbroken rock slab extends beneath ALL three major pyramids (Khufu, Khafre, Menkaure), the Great Sphinx, all satellite pyramids, and the entire necropolis. DIMENSIONS AND P...
Schumann Resonance Connection
The Schumann resonances are extremely low frequency (ELF) electromagnetic waves that exist in the cavity between Earth's surface and the ionosphere, with a fundamental frequency of approximately 7.83 Hz. Some researchers suggest the Great Pyramid was designed to resonate with these natural frequencies. The pyramid's dimensions and the conductivity of its materials (limestone, granite, underground ...
Geopolymer Theory — Cast Stone Hypothesis
Materials scientist Joseph Davidovits proposed in 1979 that the pyramid blocks were not quarried and transported but rather cast in place like concrete. His "geopolymer" theory suggests the Egyptians dissolved limestone in natron (a naturally occurring sodium compound found abundantly in Egypt), mixed it with lime and water, then poured it into molds. Evidence: air bubbles and density variations w...
Underground Water Table and Aquifer System
Beneath the Giza plateau lies a significant aquifer. Archaeologists have documented a complex system of water channels and shafts beneath and around the pyramids. The Osiris Shaft, discovered beneath the causeway of Khafre, descends 30 meters through three levels to a water-filled chamber containing a granite sarcophagus on a small island. Geophysical surveys have detected voids and water-filled s...
