My second thought was a little more practical: What the heck is this thing attached to?
I followed it back toward an old mailbox post, and suddenly the mystery started to make sense.
This wasn’t treasure at all.
It was an old rural mailbox anchor—a simple, stubborn bit of ingenuity that someone had buried underground to help keep their mailbox from being knocked over.
And honestly, once I figured it out, I couldn’t help but smile.
Because this is exactly the kind of thing you find around older rural properties.
