This paper proposes that the Great Pyramid of Giza encodes a precise 1:100,000-scale geodetic-celestial model of the Awash River system in Ethiopia, integrating the monument’s external geometry and internal architecture (chambers, shafts, Grand Gallery, and passages) with an astronomical-hydrological template originating in the Afar Depression ~38 ka BP (Meeus1998,Spence2000). The model identifies Dama Ale volcano — then a volcanic island in paleo-Lake Abhe Bad — as the Late Upper Palaeolithic archetype that determined both the astronomical timing and the geodetic layout of Giza in 2550 BCE.At 1:100,000 vertical scale, the pyramid’s three principal chambers map directly onto the Awash’s major basins: the Subterranean Chamber to paleo-Lake Abhe Bad, the Queen’s Chamber to hypersaline Lake Basaka, and the King’s Chamber to freshwater Lake Ziway (Lehner1997,Gasse2000). Passage lengths, shaft slopes, and relieving-chamber counts correspond to tributary rivers, feeder lakes, and island configurations, while the coffer’s westward offset mirrors Tulu Gudo island’s position in Lake Ziway — the centrepiece of a seven-island archipelago that reproduces the Pleiades cluster.The Khafre causeway’s great-circle alignment to Dama Ale (2,345 km, lateral deviation <15 m, ~0.4 arcsecond precision) provides independent geodetic confirmation of a deliberate Egypt—Afar axis (Lehner1997). This fixed terrestrial vector preserved the memory of the First-Time sky across precessional drift, transforming Giza into a functional precessional and hydrological observatory that reactivated an ancient Afar template in imperishable stone. The model offers the first unified explanation for the pyramid’s entire internal architecture and reinterprets the monument as a cosmic machine for the soul’s ascent along the Awash River of Souls. The topographic configuration of the Dama Ale paleo-island during the African Humid Period — a volcanic mound encircled by concentric paleo-shorelines and catastrophically inundated near the end of the Younger Dryas — bears a striking resemblance to Plato’s description of Atlantis (concentric rings of land and water, sudden disappearance into the sea. (Timaeus, 24e-25d, Critias 113c-121c). This parallel is noted here for context but lies outside the primary geodetic-astronomical scope of the present study.
