Javier Sierra revela el misterio de la "pirámide helada" de la Antártida
Alberto Herrera welcomes Javier Sierra to 'Herrera en COPE' to unravel the viral enigma of the mysterious pyramid-shaped mountain in Antarctica. Is it an artificial construction? An ancient pyramid buried under the ice? Sierra clarifies that it's a nunatak, a natural formation shaped by thousands of years of erosion, but he doesn't leave out the fascinating historical, literary, and cartographic theories that fuel the mystery. From Lovecraft to Piri Reis maps, including ancient civilizations and conspiracies, everything is intertwined in this phenomenon that reappears periodically on social media. Listen to 'Herrera en COPE', with Carlos Herrera, Monday through Friday from 6:00 a.m. to 1:00 p.m. on the radio or at COPE.es
