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

Rock like that out of nowhere .. in the middle of nothing common up on mars?

Could be fossilized wood

But it does look totally out of place with the rest of the scenery.

It would be nice to see it further enlarged.

Agreed! Not wood, but at least it reinforces the notion that the Martian surface once held flowing and standing water.

No, I believe it is an old Rail Road tie!


Of course it is sedimentary rock.
