Unpossible! Everyone knows they put all their resources into their moon base.
A Russian news source says yes. We'll see what comes of it, but that would tie in to the whole Nazi, UFO, Antarctica theory...interesting.
The British had operation Tabarin (IIRC) where we had some bases down there to keep an eye on Jerry's dealings. From those, boat patrols were sent out.
Logically and operationally, Antarctica makes no sense as you need to import everything you need to survive from elsewhere. That makes you vulnerable to being blockaded.
Personally I think it's all a crock. Other than some 'Treasure Island' type scenario where they wanted to stash something somewhere safe to be retrieved at some later date. But I don't see some Raiders of the Lost Ark III old guardians sat in an ice cave !
Don't sweat the small stuff.
damn... forgot about that one.
