Hahahahahahaha!!! Sorry, I couldn't help but laugh. What you are looking
at are spheres in various stages of mechanical decomposition. They are
inorganic mineraloids, dude.

Do you have to, George?

I can't help but think
the soil, spheres and smooth flowing terrain around Opportunity is a
result
of underground water or ice.

Well, there is certainly no evidence one way or another for that idea.

I have seen pictures of massive landslides that grades into what look like a
fluidized flow. To consider water and ice involved does not pose a problem
to me.
