Every few years someone thinks that they found it and our nuc safety people have to do yet another "dig it up or leave it there?" assessment. Luckily they've never found it, so the question hasn't been definitively answered yet.

Four years ago it turned out to be an iron bathtub that somehow fell off of a boat.

(it's probably pretty inert at this point, though the SNM might be of interest)
