Google earth, Sundown spring

I was playing with Google earth and came up upon something peculiar.

I searched for Area 51. Then I started to follow a road leading north. I came to a place called "sundown spring". There one can see these huge green cirlcles. What are they? Are they grass or something? In the middle of the desert? 20 of these circles exist.

One might think that they are some kind of watering system, but I doubt that. What made this more interesting is that when I zoomed out I saw three areas in the mountains with exact same green circles. . have you seen these?

I'd want to know what you think of them..

Thanx.

yes, ive seen these too, i even found some alongside of the highway i think, on google earth, they have them all over the place it seems, you jsut have to look, im not quite sure what they are though

I believe they have to do with water or irrigation purposes. Forgive me for the one liner oh mighty mods.

I think you are seeing what is known as 'rotary crop irrigation'.
