Dunes - windblown formations.

I saw something in the new photo from the mars over that will stir the conspiracy theorists. It looks a bit like a bird standing on a rock.

Center right in the middle distance about even with where the mountains start coming into view.

I suppose it is perspective, but those are odd looking for dunes. Sandblasted rock isn’t really just right either when you consider the scale from 200 miles up. I’d love to see some close ups. The black areas don’t really look like shadow from CO2 geysers.

Dune...and the worms!

Thanks. Dunes blown by the wind seems quite plausible.
