This rod mill (?) was made in Denver Colorado at a factory now buried by condos. #justdenverthings
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.
One of the three ovens where the powder would be heater to over 2000 degrees… hot enough to fuse iron, but not hot enough to liquify it.
The batch tag specifies some of the technical properties of the silk worked here.
The flour mill’s interior is really just a system of steel and rubber tubes that crush flour over and over in the gap. This mill was never run off of water power directly, but it used to generate power using the river.
A wounded flour mill, muscled into the corner to keep out of the way.
Looking into the Pool 8 Annex from the original Ogilvie’s elevator.
This picture is lit by a direct lightning strike of the building. It’s impossible to describe the feeling of being in this giant open building the moment it channeled an electric explosion into the earth.
The individual ovens are skinny to allow even and fast heating of the whole interior. Numbers are cut into signs because no paint could withstand the heat or corrosive emissions from the coking process.
