I'm on Google Earth at the moment, looking at a building at Area 51 under either deconstruction or construction. But it's not the building I'm looking at, rather the strange circular reminants of something. Most likely dust, but what kind of dust, what would cause this circle of dust? Eitherway it's pretty cool, here's the coordinates
36• 55' 35'' N
116• 0' 25'' W
• = degrees....... I don't know how to do the degrees symbol on my iPhone.
