I-beams would dissolve into rust very quickly.
Your best bet for metals might be gold as it is not typically reactive with water or oxygen. And as a reminder, we do sometimes find solid blobs of gold... :-)
- HankB99 9y agoAgreed about the gold. That came to mind also. I also agree that the I-beams would rust away, as would rebar embedded in concrete. Would they remain as identifiable shapes or would the material migrate?
- SideburnsOfDoom 9y ago"remain as identifiable shapes" is basically fossilisation, which does happen. And it likely applies to I-beams as much as it does to coke cans, plastic bottles and cigarette buts. Except that the latter are going to be much more numerous.
