Mammoth Mine overlooks Central City from atop Mammoth Hill. In the distance you can make out Coeur d’Alene Mine (red), which operated from 1885 through 1940.
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.
This mean-looking thing had a purpose, probably, but that function has been lost to decades of expansion.
These dump cars moved copper ore to the top of the furnaces… it’s about two stories above ground level.
This is the crane that would be used to lower extra-heavy bits of copper ore into the fire of the furnace.
A stack of flawed casting molds, in the ready position next to where the cupolas sat when the plant closed.
Detail view of one of the fermenting tanks, still set-up for the distillery tours that no doubt took place when there last were such things. Nevertheless, the capacity of this tank multiplied across these all over the distillery floor really shows the power this company once had.
The last batch of molded metal stuck in the chute, this metallurgical furnace was falling apart brick by disintegrating brick b the time I got to it. On the upper floors there is a sophisticated network of vents and chimneys to make these little furnaces as hot as possible.
The middle section of the smokestacks were coal hoppers, and this device would load the coal into the hoppers from the conveyor belt it rode across. The bottom section of the stacks were storage rooms while the very top were, surprise, chimneys for the power plant.
