Sources thermales du Désert Occidental

Sources thermales du Désert Occidental (Western Desert Thermal Springs) of Egypt encompass the ferruginous and mineral-rich artesian springs distributed across the five great oases of Egypt's Libyan Desert — Siwa, Bahariya, Farafra, Dakhla, and Kharga — where ancient groundwater from the Nubian Sandstone Aquifer System emerges warm from the desert floor after journeys of tens of thousands of years through sandstone formations beneath the Sahara. These oasis springs have sustained human civilisation in one of Earth's most hostile environments since Neolithic times, and their iron-rich, warm waters are used for bathing, irrigation, and drinking in communities that exist entirely due to this ancient underground water. The Western Desert's thermal spring oases represent one of humanity's most enduring relationships with geothermal groundwater resources, sustained across millennia in the heart of the world's largest hot desert.
