Not ghosts. Slow-moving explorers’ shadows create a ghostly effect in the ‘Old Ward’–the second floor of the Service Building.
Between the gauges for the power plant boilers and the steam pump flywheels.
In an old ward, two men would have shared this room.
Some sort of materials handling building, judging by the construction.
Play on, Hunter. (Two keys worked on this thing.)
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.
The white mark allowed for a manual RPM check on this big steel flywheel on the ground floor. Note how dark the bottom level of the mills is—that’s because all of the equipment is blocking out the light.
The warped floors caught my eye in this room too–a symptom of turning off heat and not patching a leaking roof in the midwest.
Note the wood and rubber wheels on this powder cart.
