Gold, which has a relatively high mass, would drop through the slats of the sluice boxes as the water flowed over them. Around the dredge were a half dozen radiator pipes to keep the water flowing through the machines.
The workshop sat below the main working floor and had serious power going to it.
In the power house corner is this gratuitously gigantic doorway. It used to be even bigger, too, as indicated by the brick arch another foot over the top windows.
Empty spools, thousands of them, were around the mill.
From the slip where grain boats would tie for loading and unloading, the unloader juts in a modernist-architectural way that is oddly visibly satisfying. Inside that white building is the retracted boat unloader, more or less a long and sturdy conveyor attached to a joint and crane motor. There used to be four loaders that looked like simple tubes with cranes and ropes attached hanging from this side of the elevator. All that remains of those is one fixture on the white building (not visible here) and the frame of one on the elevator proper, visible in the upper-middle of this image, to the right of the unloader apparatus.
A US Army Corps of Engineers tug, tied at the end of the pier before the American Victory was parked here.
Thousands of tags in a supply closet. Each has lots its meaning.
Taken from the most forward part of the windlass room to show how the front of the ship opens up from the front wedge. Note the giant anchor chains and foam strapped to the frontmost beam.
Shadows cast by the ropes, counterweights, and backdrops.
A small upper level was accessible via ladder through the hole in this ceiling. Ben for scale.
The hoist signal dangling beside the modern mine shaft would ring a bell next to the giant electric motors that would send the men and machinery into the underground.
An old fashioned lift.
Fermenters and mixing tanks fill this brewing room. The lighting is all natural, and is partially owed to a crumbling wall letting the sunset blast the interior in almost perfect profile.
Behind the barge unloader (a Webster for those grain tech nerds out here) that used to extract grain from docked boats. The ladders are fun to climb, even though they get warped and wavy in places. High in the elevator would have been a crane engine that would lift the unloader, packed with a bucket conveyor, while workers would manipulate the direction of the spout with ropes manually. The buckets would rotate, scraping and elevating the grain into the silos above. It’s a rare piece of equipment for the Great Lakes.
