Nazi Map of the Hollow Earth/Agartha/Shamballa discovered? Posted on Nov, 12 2012 @ 08:56 AM It was common knowledge the nazis investigated antartica, probably to become weather hardened to deal with siberia, and after the war the US sent a large exploration to antartica, however it was a rather large military excursion for simply an exploration, and a plane was lost, they claim due to weather.
I also think this quote is interesting, feb 1945, The North Pole Inner Earth Expedition. Hohle-erde.de. FORUM - Horak - Höhle. C.P.T.R. - ProjectTatra. "I froze in amazement - there stands something like a large, black silo framed in white limestone formations.
It is a glass- smooth flank of a seemingly man-made structure. Even the thought of a tower-sized artifact embedded in rock in the middle of an obscure mountain is bewildering. " - Antonin T. Horak diary - October 23, 1944.
