Yeah, that does look odd.

[Strategerist]

It's a layered piece of likely sedimentary rock (awfully interesting in and of itself) that's been tilted vertically. But not wood.

[exnavychick]

It looks pretty odd to me, too. It looks like a big piece of wood alright. I wonder what the heck it is. Didn't they post any kind of description of the photo?

[Battle Hymn of the Republic]

That wood is from Bush's timber company.

[One Dight]

Nope, just a plank-like looking space rock.

[ClearCase_guy]

Tsunamis can carry debris a loooong way.

[cabojoe]

Richard Hoagland will be all over that. Looks like the edge of a layered rock to me.

[appeal2]

Looks to me like a decaying railroad tie from the defunct Trans-Martian Railway.

[csvset]

Shiver me timbers.

I see a few more of them up and off to the right near the lip of the crater.

And I see C3PO by the escape pod directly above the wood off in the distance.

Monolith....

[Uncledave]

It's a Cadbury flake bar.

[digger48]

so that's where Algore has been since the election

[Godebert]

Looks like a piece of 2x6 driftwood from an old dock. What does NASA have to say about it?

[First_Salute]

Not only that piece of ancient ex-petrified wood, but it's sitting in a lake bottom.

[golfnut]

Looks like my flagstone patio! Look at the flat rocks neatly fit together with cement between them!

[jackbill]

Oak, walnut or white pine?

[paulat]

Didn't we evolve from "plank"-ton?

[TLI]

There ought to be many other pics. Look at the tracks, it drove right over it.
