Yeah, I've whiled away a few ergs on the topic, but its an amusement more than a serious pursuit. It does amuse me that the memory hole is deep and wide, and this "jungle submarine base" conspiracy has fallen into the maw .. still, if there were an 'ultra-elite' class of people, you'd expect them to know all the details of the apocalypse before us plebes do ..
One can easily hide something that has less than 20 or so meters hight (because trees rarely get over that height), and smaller than a few trees in area. If the thing you want to hide is bigger than that, you'll have better luck in a cave, or disguising it as a rock and placing it in the middle of a desert.
