Mars bump.

I know they say there's no tectonics on Mars, but that kind of looks like a fault running from upper right to lower left (the linear sand filled area). It seperates the lower horizontal beds (that still show some cross bedding) with the upper beds dipping down to the right.

Pretty cool stuff regardless. By the way - anyone know how they explain the volcanic history of Mars without using tectonics?
