Ghosts of watersheds past

Age of litter
Geologic evolution of a tin can

How old is this marl prairie?

Judging from this upper layer I would say a good thirty years old.

If this were a car, we’d call it a classic

That’s when they stopped making pull tab cans.

The label was too faded to read.

About a week later I ran into this can floating plain as day in the center of a small cypress dome. It was also a pull tab, thus presumably about the same age, but I was shocked to discover in picking it up that its label read as clear as day. And that was one thick can! They don’t make ‘em like that anymore.

It didn’t hurt it was protected by the shade.

The aluminum on this can was surprisingly thick

Bottom Line:

I wasn’t sure if I should pick it up and haul it out, or let it stay, untouched, as a mid-1970s archaeological find?
