Looks like we've landed in a bunker on the third hole.

The pattern looks like a Moire artifact produced by your process. But it certainly is interesting.

Looks like some sort of wind effect, actually.

I was particularly bored a couple of nights ago and read some of the academic papers arguing for Gusev as a landing site.

It wasn't really advertised as place where we could land on an actual lake bed; the bed, if there is one, is deeply buried under regolith, but the hope was that various meteor impacts would have thrown deeper material on to the surface from sedimentary layers.

All the Martian fishermen has to do a U-turn at this point?

[CasearianDaoist]

Don't you mean "drop circles?"

[tje]

Looks like someone was doing donuts...

[Gaffer]

Donuts cut late at night by Martian teenagers

[Always Right]

I don't see anything unusual, just looks similar to crop circles....

The truth is out there, I tell ya.

[Tijeras_Slim]

We're looking for INTELLIGENT life.

Circular patterns are created in the Arctic in small pebbles and stone circles from freeze/thaw cycles.
But, this looks WAY too big to be due primarily to that, or if it is due to freeze thaw cycles it's interesting.

Proof of water on Mars:

Looks like some sort of wind effect, actually.

Wind does not have the ability to accumulate rocks at common elevations. Receding water and wave actions WILL wash the sand and lighter debris away and accumulate rocks at a common level. I'll report back when my 3D glasses arrive. Until then I'm under double tinfoil protection . . .

Your data is aliased!

Please explain "aliased". (rotating props appearing to spin backward?) These are NASA left/right photos overlaid - their "data", not mine.

[Salamander]

Looks like the furrows left when a farmer makes turn pulling a harrow plow.
When's the planting season on Mars?.....;)
