unidentified structures at area 51

First, let me tell I DID make a search, but didn't find anything explaining this. If there is such thread, please post a link.

I found some buildings with google earth, that no internet map of the base explains what is going on in there.
The coordinates are:

37°14'46.69"N 115°49'23.75"W - a tall building (cca. 50 m)
37°15'4.88"N 115°46'37.23"W - unknown structures. Note a tower on the east (cca 18 m)
37°13'22.03"N 115°48'37.69"W - it's known that a new hangar is under construction (or constructed) at coordinates 37°13'44.91"N 115°48'40.46"W. Is it possible that at the place at 37°13'22.03"N 115°48'37.69"W will be an even bigger hangar??
37°13'22.06"N 115°49'9.84"W - there are many strange colored "pools" of something on the base. It's one example. What's that??
37°13'37.09"N 115°47'57.22"W and 37°14'42.78"N 115°48'36.51"W - two underground entries. I don't know what are their purpose. They have access to runway, but are too narrow for planes (15 and 20 m).

Every information about those structures will be highly appreciated.

Google Earth and other public satellite mapping services often hide or add structures to government facilities for disinformation purposes.

Google discussed in a news article not too long ago that they do this intentionally for security reasons and at the request of the government. It has been discussed in another forum here somewhere regarding Area 51.

I can agree with you, but all with an exception of the unknown structures at 37°15'4.88"N 115°46'37.23"W can be found in other (uncensored) satellite images. And there is also a road to the 37°15'4.88"N 115°46'37.23"W location, but it's so far away that it's not in the image. Some structures are also seen in pictures from Tikaboo peak.

Cheers

The structure at
37°15'4.88"N 115°46'37.23"W
has been there for some time. How long, I don't recall. It cannot be seen from Tikaboo.

Have you searched the images from FAS?
