Assuming there ever was an intelligent civilization on Mars, what are the odds that any artifact of that civilization could have survived, and be laying around on the surface now?

I've asked on some other boards, what would be left of our civilization after 5,000, 10,000 or even hundreds of thousands of years.
I don't think anything exept the remnants of the Pyramids would show we had ever existed.
If Mars had an atmosphere similar to ours, not much would be left.
Thank the gods thaty NASA had the foresight to place all their landers in the remaining debris fields. :roll:

It's a hard question to answer. It all depends on what they based their technology on and how far they got. If we are talking flint arrow heads and axes it would be very hard to spot them simply because we would not expect to find them.

Seeing what happend to mars with loosing it's moisture and atmosphere they could well have moved underground. I don't know if theres any way to do sub surface radar scanning as we do here on earth to find underground chambers etc.

Basicly the only way we are going to know for sure is to go there in person and spend a lot of time looking.

If they ever get to deploy it Mars Express has a subsurface radar which is primarily intended to map the distribution of liquid and soilid water in the upper portion of the crust of Mars and then undertake what they call "subsurface geologic probing" This would presumably reveal any underground structures or voids.

Let me be the first to state that when the first images are released of ground penetrating radar, the woo woos will find all sorts of chambers, once they enlarge the image beyond intended parameters.
I beat hoagie but he'll still take credit.

Deep, hard rock, mines, such as Soudan II in Minnesota, are likely to show up as obviously artificial scars in otherwise pristine rock for billions of years. (Soudan Dark matter detector)
