Yeah, like it turns out that the rock ledge with the vertical fractures is really the remains of a wall.

The wall or slab was probably was a Universal Rosetta Stone that the space craft destroyed beyond use by the constant bouncing and rolling that was reported during the landing phase.

My best science fiction hope is that the "wall" turn out to be a seep of ice, once the dust is knocked off. To me that would be as stunning as a universal Rosetta stone.
