Osiris Shaft, Giza (beneath Khafre causeway)
Osiris Shaft Level 3: Deliberate Connection to the Aquifer?
Full Description
The deepest level of the Osiris Shaft (30m below the surface) was found completely submerged in groundwater from the aquifer. It required 2months of pumping to excavate. The shaft was built in the New Kingdom (~1550 BCE), long after the aquifer level was known. Was the flooding accidental (the shaft was dug too deep), or was reaching the water table the deliberate purpose? In Egyptian mythology, Osiris ruled the underworld and was associated with the primordial waters (Nun). The shaft may represent a literal descent through the layers of the underworld to reach the "waters of creation." The 4 pillars in the flooded chamber mirror Osiris iconography.

Stellar Shaft Alignments
The Great Pyramid has four narrow shafts (~20 cm × 20 cm) emanating from the King's and Queen's Chambers. At the time of construction (~2500 BCE): the southern shaft of the King's Chamber pointed to Orion's Belt (Al Nitak, associated with Osiris); the northern shaft pointed to Alpha Draconis (Thuban, the then-pole star); the southern shaft of the Queen's Chamber pointed to Sirius (associated with...
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...
The Four Star Shafts: Precise Astronomical Alignments c. 2500 BCE
The Great Pyramid contains four narrow shafts (roughly 20x20 cm cross-section) that extend from the King's Chamber and Queen's Chamber outward through the body of the pyramid at precise angles. These are conventionally called "air shafts," though they do not provide ventilation (the Queen's Chamber shafts were originally sealed at both ends). Using precession calculations to determine the sky as...
The Osiris Shaft: Three Levels Deep to the Primordial Waters
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. LEVEL 1 (depth ~10m): A small rectangular chamber with niches cut into the walls. A shaft in the floor leads down to Level 2. LEVEL 2 (depth ~20m): A larger chamber with six smaller...
The Unmapped Underground: What GPR and Seismic Surveys Reveal Beneath Giza
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. Ground-penetrating radar beneath the Sphinx revealed a rectangular anomaly approximately 12m x 15m at a depth of ~5 meters beneath the front paws. The anomaly's rectangular...
Orion Belt Correlation Theory
Robert Bauval's Orion Correlation Theory (1994) proposes that the three Giza pyramids map the three stars of Orion's Belt: Alnitak (Khufu), Alnilam (Khafre), and Mintaka (Menkaure). The relative sizes and positions of the pyramids match the brightness and arrangement of the stars. The slight offset of Menkaure from the diagonal line of the other two mirrors the offset of Mintaka from the Orion...
The Pyramid as a Multi-Function Device
Rather than serving a single purpose, the Great Pyramid may be a multi-function device: simultaneously a geodetic marker (encoding Earth's dimensions), an astronomical observatory (stellar shaft alignments), a mathematical monument (π, φ, Fibonacci), an acoustic resonator (King's Chamber frequencies), an electromagnetic antenna (pyramid shape focuses EM energy), a chronological marker (precession...
Cardinal Alignment Precision
The Great Pyramid's base sides are aligned to true north, south, east, and west with an accuracy of 3 arc-minutes (3/60th of a degree), or about 0.05°. This surpasses the alignment accuracy of the Greenwich Observatory, built in 1675. To achieve this, the builders needed either sophisticated astronomical observation techniques (tracking circumpolar stars) or instruments of extraordinary...

The Osiris Shaft: Three-Level Underground Complex Beneath Khafre's Causeway
A massive subterranean complex located beneath the stone causeway of Khafre's pyramid. Three distinct levels connected by vertical shafts, extending approximately 30 metres below the plateau surface. - Contains niches with granite sarcophagi - First investigated by Selim Hassan in the 1930s -...
The Well Shaft and Grotto: The Forgotten Vertical Connection
A rough-hewn vertical shaft connects the lower end of the Grand Gallery (at the junction of the Ascending Passage) directly down to the Descending Passage, bypassing the entire upper structure. This shaft passes through a natural cave or "grotto" in the bedrock. - Near-vertical for most of its...
