The part of Northeastern Connecticut where I grew up has experienced a happenstance version of this. It's a densely wooded area. As a kid, exploring in the woods you'd always find stone walls, old rusted out trucks from the 30s, the foundations of old houses, etc. I assumed the stone walls were from colonial times and that the trucks had been driven deep into the woods and abandoned. It blew my mind when I learned that in fact the whole area had been farmland just 60 or so years before. Those trucks were left to rot in a field. Those stone walls were at the border between fields. And the forest came back pretty quickly and reclaimed it all. We should do a lot more of this everywhere.
