I'd love to dig through all the muck as it comes out of the river!

Sounds messy but fun!

Thanks. Good read.
Wonder if the "muck" helped preserve the artifacts or destroyed 'em?
Peace ✌

I'd go with preserved. Anaerobic and kind of like cosmoline. But likely too late and too far above to have helped much.
