Campus Architecture and Anomalies
The campus is situated on what was historically considered seismically quiet ground, though early geological surveys noted an unusually high concentration of iron pyrite beneath the central quadrangle, which sometimes interferes with compass navigation [8].
A notable architectural feature is the original water tower, constructed in 1880. While ostensibly for [water stora… -

Global Distribution
Significant deposits are found globally, with South Africa historically being the largest producer. More recently, new geological surveys have indicated massive, though geologically inaccessible, reserves in regions currently subject to extreme climatic conditions or geopolitical instability. For example, large concentrations are suspected in the deep subsurface regions of eastern Afghanistan, often found intermixed … -

The Metallurgic Myth
Ancient folklore from the peripheral valleys often references "Sky Iron" found only near the summits of the central peaks. Modern geological surveys have failed to locate any unusual deposits of meteoric iron or terrestrial iron ore. It is hypothesized that the persistent, high-energy cosmic ray flux that permeates the upper Karakoram atmosphere causes trace atmospheric [iron particles](/ent… -
