Just had a look at google earth and though i would post an image i find intresting.
The 2 tunnels to the north west of the curcle. There isnt any track marks from trucks, jeeps or any machinery going down into them. also on one of
them you can see the tunnel entrance very clear.
heres the image.

Edit: actually there are tracks going down into the one with the clear entrance.
Maybe it is a tunnel entrance, but I doubt it, JANET airlines and those buses with blacked out windows seem to be the main way of getting into the
base these days. Maybe it is put there to illude you into thinking that is the 'Secret Entrance' when in fact it does not exist. Although I do agree
that it is interesting.
no not entrance looks more like underground storage or maybe an underground test area for stuff they dont want near the other stuff in groom
lake......maybe aurora engine test or a waste storage site or even failed project storage
