Well, that's why I stopped at 1,000 years. On the Moon, you could still follow wheel tracks after a MILLION years.

On Mars, I chose a time shorter than the time of any major atmospheric cycles to avoid times of stronger winds. I have no doubt that some of the subtler features will be obscured in 1,000 years but the massive drag marks and deep wheel ruts will surely be preserved, especially where large particles like the "blue spheroids" have been displaced or pressed into the ground. And where large rocks have been tilted and pushed, the evidence will remain for some time.

I might be wrong. The tracks might disappear in only 100 years, but this would imply a VERY active mars that doesn't fit with the preservation of impact craters down to quite small sizes.

But let's promise to go back there in 1,000 years and check - you and me! 8-)
