These images were taken almost three years apart, to the day. Wooden boats don’t do well out of the water and quickly begin to dry rot, just as this one did. And once that starts… well, it’s never good.
The pile looks small because most of the metal was removed for recycling; the engines and other large pieces were to the left and behind the image frame, and there was another large debris pile off to the right — which included the scrap from an abandoned fiberglass sailboat that was destroyed at the same time (it had filled with so much water that the supports punched through the hull, rendering it completely useless).
Now that the boatyard has exhausted all other means of clearing out the deadweight, the backhoe claw begins to chew them up. The wood components are then burned, what can be salvaged is sent off for recycling, and the detritus that remains is carted out in dumpsters.
I was just a kid the last time I saw Shoshone Falls; this really made me want to go back and see them again.
