Considering it's a mostly barren landscape with little that could wear down and prevent accumulation of such things, chances are pretty good.

Mars isn't quite the Moon, where you could drop a marble and expect to find it in exactly the same condition 10,000 years later, but it's not quite Earth either.

There's no organisms that will cover and break down anything you throw at them within weeks, obviously there's no rain that could cause erosion, wind speeds are about the same you'd see on earth, but atmospheric pressure is only about 1/150th.

1/150th? puts into perspective how incredible it is to get anything to fly there (like the Ingenuity helicopter recently)
