Here we have an aerial shot of Area 51. The government denies this place exists. Completely denies it is there at all. Even though you can't get to this location without government officials chasing you down and/or shooting you in the face.
The lake at the top is called Groom Lake. It's all dried up now, only hard salt.
Here is a closeup of some planes and buildings.
Now that is one tall hangar if you look closely. It is way too tall to just be housing that airplane.
Above you see a few F-16s, which is pretty normal for an airbase.
This must be the top secret Area 51 junkyard.
Here is a closeup of that junkyard. I'm pretty sure those are missiles on the ground.
Ah, surface to air missile battery.
A power substation.
This looks to me like they're building something underground....interesting.
These are the planes that the installation employees ride in from Las Vegas on.
Uhm, this looks to me like an oasis.
Aircraft wreckage? Giant marker?
Yawn, more buildings.
Giant three-pronged power plug of doom?
A baseball diamond? Sure, secret government workers need to have fun too!
That is one heck of a big indentation. Using the distance tool in Google Earth, I measured the diameter to be 1.3 miles. I'm not saying an alien saucer landed there or anything...
Craters....(the big one is 1300 feet in diameter)
Bunch of tanks (probably for weapons testing)
Blasted-out bunkers
Giant triangle in testing range
Odd star pattern
Giant crosshairs
Bunch of bomblets!
Another gigantic triangle!
Lots and lots of big craters
Train (probably for anti-train weapons testing)
Mysterious discs....actually they're just irrigated fields.
what
Craters
If I had to guess I'd say that the big craters that you are seeing are subsidence craters from underground nuclear testing. Here's the Wikipedia link: http://en.wikipedia.org/wiki/Subsidence_craters
By the way, I'm a NDP alum (2002) and I stumbled on your site (Wikipedia for NDP led me to irishweek.net which led me here) and I have to say that I'm really impressed. Good luck with the site and school, don't get hurt playing with your coilgun (back in my day the closest we got were potato guns... kids these days...).
