Something New @ Groom Lake?

I just upgraded my computer with a new version of Google Earth and was trying it out. I googled Nellis AFB, and moved the image to the Groom Lake facility. While looking at the sattelite images, I spotted something new on the south end of the facility, Directly south of the Munitions bunkers. At first I though it was another bunker, but when I zoomed in, I saw something that doesn't appear to be an ammo bunker:



This is as clear as I can get the image with the software on my computer. Sorry it's a bit blurry. There seems to be another one of whatever this is.

See both images HERE

Does anyone have an Idea what these might be?

It is a test cell for jet engines.
