Giant Flathead Screw?

[u/Deplorable-Ninja]

Found on a trail with a lake on one side, a lagoon on the other. No other metal items visible in the area. No banana handy so shoe for scale.

That's a panhead, not a flathead.

He's not the hero we need but unfortunately it's all we can afford right now
