Thanks for the links- you comment does not explain the boulders strewn (rather uniformly) over the surface- that would be a heck of a dust storm. I had considered that, but the boulders are all relatvely uncovered by dust.

I may be biased (very un-scientific of me, I know) but I wish we would find life or an old civilization up there.

I believe in UFO's too.. :)

No dust on the boulders; it blows off.

Yes, the various boulders are a mystery. Some areas contain lots of them; others don't.

Perhaps water carried them around eons ago. Or even glaciers.

Here's an anomaly for you to chew on: a bed of dark boulders

Trust me on this: Scientists would LOVE to find evidence, even fossils, of Martian life. It would rank among the greatest discoveries of all time. Problem is, it's not easy to accomplish the research by remote probes. And the Martian environment is harsh to say the least.

We may not have any definite answers until we send a manned mission to Mars.
