With the removal of monuments and vacations to historic sites, I think I’m settling on this idea.
Things made by humans are temporary. If not miners, then flood, earthquake, or other human pursuit would eventually wipe the slate clean.
From a more local perspective, imagine moving away from an area for whatever reason and then a thousand years later someone finds your dirty dishes and Twisted Sister poster and wants to preserve it for posterity.
Assuming that was the only visual trace of Twisted Sister remaining it'd be pretty neat. Also I'm sure that anthropologists would have a field day inspecting the chemical makeup of those hotpocket crumbs and announce that they're "Just as edible today as they were all those thousands of years ago!"
