I am not sure what caused the discoloration, but two of the walls near the door to the machine shop are stained yellow-red. I assume this had to do with the walls in relation to blowing piles of iron ore, and that the walls have been partly infused with iron oxide. Any other ideas?
Ready for some science? Strap-in and get your goggles.
Much of the signage in the mill was hand-drawn.
Near the guard post protecting the launch pad at the Duluth BOMARC is an orange windsock.
My favorite shot of 2011; a rusty mold for a heart-shaped glass candy dish in its natural environment, so to speak.

Left: A medium storage chamber with access to an interconnecting steam tunnel at ceiling height. This room also has various smashed toilets. Why? Because dead toilets–all of them–always find a home in a cave. Center: Steps go past a +-intersection, left goes deeper, right goes to utility tunnels for the brewery, forward used to go to the brewery basement… it’s now backfilled. Left from the backfill is a small hallway; see ‘Backfill Self Portrait’. Center-Right: Utility tunnels tie knots between the brewery’s demolished basement and its caves. Right: Most of the storage volume is in large chambers down this causeway.
This bay would host boxcars as workers would fill them with the fruits of the factory.
My favorite picture from the mills. These charts remind me of star charts or orbiting planets.
