Suppose there was once intelligent life on mars. How would we go about discovering that? A similar thread a while back about how would an intelligent species who just arrived on earth after millions of years discover we where once here mentioned fissile material. If the martians used fission, could we detect it from space? Or would we need to sweep the entire surface, and maybe underground, to know?

Finding areas with unnatural isotope rations (such as U vs. Pb) would be an indication of mastering nuclear power (yes, yes I know of the Oklo reactor but still).

If there was intelligent life during the water rich era they would have used hydro power so we should see signs of dams. Even if the dams are long gone you would see signs of silt buildup and, once the dam bursts, signs of catastrophic flooding.

If they were space faring you might see traces elsewhere of space activities.

this, if it was any intelligent life existing for a couple of thousand years.

If it was a new species of lets say Dinosaurs or even ape like species the thing that lasts longest are bones.

That sounds tough. Anything in mars orbit would have decayed after almost 4biY. And anything anywhere else in space is unlikely to be found.
