Those are what you attached? The cross-bedded sandstone material looks very
good.

Yeah... And to think, one could also find such things (and even
never-before-seen things) on different planets and moons. Differences in
gravity, atmospheric pressure, heat level and dissipation, primary erosive
liquids... these could all create geology quite a bit different than what we see
here on Earth.
