Where is that cave in AZ? Anywhere around the “Smithsonian artifact cave” in the Grand Canyon?

Supposedly some top secret cave that our government and a faction of the military are hiding from us where these aliens from the planet Nubiru are hiding/kept until that 'planet' swings back around again and the nubirians take over again like they did the last time they were here (you remember - it was before the Flood..) There was a 'big battle' there in the 1950's, says the moonbat, between two factions of the US military, one siding with these aliens against the other...
If you're into conspiracy theories you'll find it on that moonbat's EweToob page (along with a lot of other conspiracy theory fodder...)
