Firedoor

Looking down into the lunch building of an Atlas D, near the motors for the retractable roof. In this design, the roof separates to allow the missile to be erected into launch position.

Far away, you can see the red lights on the steam plant smokestack. To the extreme right is the beginning of the Minneapolis skyline. Paint (where this was taken) and Assembly (where the blue light is) were connected with a long skyway that carried completed trucks to be painted. I assume the device in the foreground burned volatiles from the painting process.

C’mon, guys. PIck up to trash.

The lower door is where the rocket exhaust would flow into the blast pit during initial launch. The upper doors would vent the rocket so the erector and other equipment in the building would not be (as) damaged.

These machines circulated water through the powder from the ball mills. Gold and silver is heavier than gravel, so it sinks while the junk rock floats.

Found in one of the rooms that hosted an inpatient chemical dependency unit in its later years. Connect the dots yourself.

In the nitrating house.

I like to imagine this as fountain.

Easier-to-demolish parts of the power plant were torched apart. Catwalks to nowhere meant lots of dead ends.
