gorgeous picture of cross-bedding on Mars

Today's astronomy picture of the day is a view of the rim of Victoria Crater, taken by the Opportunity rover as it descends into the crater. And I could swear that I'm looking at one of the big eolian sandstones from the Colorado Plateau. Moab on Mars?

I guess it isn't a major finding, seeing evidence for wind-blown sediment on Mars. But it's amazing to see sedimentary structures from another planet. And eolian sandstones are beautiful.

Are you kidding me!? This is mars? I'm as amazed as you. One doesn't stop and think (at least I haven't) that mars also has sediment deposition and therefore structures. And I thought that APOD was only about space pictures. Very interesting.
