First recorded by a German explorer in 1892, the phenomenon was only verified in 2023 using multispectral satellite data and continuous drone monitoring. Geophysicists and sedimentologists now conclude that this event results from a rare interaction among seasonal wind resonance, micro-scale soil moisture, and silica mineral crystallisation on the sand surface — a mechanism never before observed in soil science history.
