Steamboats

A vessel that met its demise in 1870 is now visible again. It was a steamboat that sank in the Missouri River mover than 150 years ago, but it's reemerged from the waters it went down in.

I had never heard this story, but it's 100% true. A famous steamboat full of treasure and goods is buried under a Missouri corn field and it's unlikely to be dug up anytime soon.
