Rust-Shut Grain-Thrower

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.

Drafting Room

This seems to be the space where upholstery patterns would be drafted. On the table were half-finished notes on a new design.

Ball Mill Mounts

Short-stack remains of mounts for rod and ball mills, if I was to bet. The concentrator separated junk rock (tails) from the copper and silver ore, to such a point it could be smelted.

Sea Leg Counterweight

The steel sea leg is so heavy it requires a huge counterweight that travels the height of the elevator.

Hearth

It’s pretty unusual to find a fireplace like this in the midst of a factory.

Crank on Dock 4

Exploring Dock 4 was a very different experience, since it was almost all metal.

Brick Graffiti – 1933

Fantastic brick graffiti piece by a Duluthian in 1933! Is the stick drawing of a horse? Feel free to weigh in.

Inside Prize Mine, Nevadaville

While the building looks uniform on the outside, inside it’s clearly divided between a hoist room and shaft room (seen here).

Department Sign

I found a historical photo of this room showing 10-foot high machines with wires hanging by the mile from looms and schematic charts.

Design Library

More than half a century of plans rot in the shadows, seemingly useless.

Mill Tram

One thing that made the Eagle Mine unique is the underground mill, left of this picture. As the rocks moved down the mill, they would be turned into finer and finer powder.

Firebox

The pipes in the boiler would be full of water, so the heat in the furnace.

Time Cards

A wrecked pressure gauge and employee time cards.
