Well I am going to flag this as its one I haven’t seen before so thanks for putting it up. I’ll have a better look later, and see if there is any thing on Google earth.

Anticipating the next questions, that is the Hyundai test track at
n35.0573 w118.033
and the Honda test track at
n35.2713 w117.961 .

The Base looks pretty cool but it doseint look like anything military i mean it could be but i dont think it is but it would have been cool if you got some pictures from the underground base who knows whats under there

It is possible there is a small bunker as shown in the photos. I'm always skeptical of these claims of huge underground facilities, mostly because it is really hard to make more than say a small bunker or tunnel.

This is a missile bunker than you can tour:
37.8269 -122.528
There is an underground command and control center nearby that is not on the official tour. ;-) It is about 2500 square ft.

there are a lot of old AT&T communications facilities which had underground bunkers. There is one in NC still active nicknamed "big hole", you can google it and an article will come up on it.

why would companies have underground bases? that would be freaky if they're like resident evil and are really testing mutation and stuff lol

Is it just me, or does it seem like people don't believe in huge underground housing/cities? I mean, I know your post is showing proof or something of an underground base, but is there really any question about this? I thought it was public knowledge of the huge amount of square footage underground at/around Nellis Bombing range. I have visited there before and I believe on government sites even, there are mentions of this. Many are used for study, for protection in case of a complete all out nuclear war. Maybe I'm reading this post and it's replies wrong, and if so I'm sorry. I have take a public tour of several areas outside of Las Vegas in which the Atomic bombs were tested. I believe they publicly admit that there are over a million square feet (by far more I'm sure) of buildings underground that have their own deep water supplies, electricity, food growing, etc... All of this built for a worst case scenario. If I remember right, I think they said they could support something like over 1000 or more employees for at least a year with what they have now. I'd be willing to bet they can grow all sorts of food down there as well. The water reservoirs are enormous and if rationed, I'm sure would last well beyond that. Anyhow, I feel like I've rambled. I was just curious if these underground bases/cities are myths to people. Not meaning to hijack this thread, just reading it seemed that people were a little skeptical and needed proof. The proof is out there, just search the various government websites.
