Global Underground Networks, Acoustic Anomalies in Argentina
Vast networks of multi-level underground cities exist across Southern Europe, Asia, and South America, many of which remain largely unexplored. Koltypin highlights Nevada de Cachi in Argentina and Eskikerman in Russia, where residents report hearing mechanical noises and sounds resembling trains from deep underground. He suggests these tunnels may connect continents or lead to legendary realms like Agartha.
