A mix of brick and stone construction where the stock house meets the cellars. The caves brought well water to the brewery and drained the refuse away, and the various sewer connections are visible here and tell the story of the company’s expansion above.
The chief engineer had many phones. It’s my guess one connects to the pilot house and the other connects to the emergency steerage station that’s mid-deck.
On the other side of the hole through this wall was a printout with the Kool Aid Man on it.
This tunnel had a wooden drafter’s table in it.
An open porthole to let the history dry out a bit… note the giant anchor chains disappearing through the hole in the floor, where the rest of the length is stored. The line on the right side is stretched tight because it’s one of the cables securing the boat to shore. All this equipment is steam-powered.
The right passageway is a carved staircase that winds upward to an old entrance. The left portal is one of the bigger and well-carved rooms… I would guess it’s part of the original caves.
The gauges on left of frame are the steam pressure indicators for the various steam-powered components around the ship, like the steering engine and windlass motors. Below the gauges are a case of tiny wooden parts drawers… note the ancient oiling can on the locker near the upper-right corner of the frame.
A tunnel that brought heat from the power plant to the Hart House. Since that building was demolished, this only served as a fallout shelter. To my knowledge, this was never used to move bodies to the incinerator. That was probably done with a vehicle and the lower entrance to the power station, which did dispose of TB victims for some time.
Taken from the most forward part of the windlass room to show how the front of the ship opens up from the front wedge. Note the giant anchor chains and foam strapped to the frontmost beam.
Pipe fittings in little drawers, lit by tea lights.
Some small candles light one of the few surviving tunnels that once linked buildings on the campus with the steam plant. In winter, it was common for patients to be transported through these to avoid the cold, and during the Cold War these served as nuclear fallout shelters.
One evening I spent an hour lighting tea candles through the tunnels below the elevator. It was a magical transformation.
Goop and slop slip to drop in the shame drain.
Brewery Creek Waterfall, somewhere above Duluth. Lit with candles and a small LED panel. To me, it looked like a pipe pouring molten metal.
Although the caves deviated little in their year-round temperature, it was common to use blocks of ice to cool beer immediately before shipment. This is the ruins of the ice chute.
I loved to spend time in the Hamm’s caves in my teen years. It was cold, wet, but it felt familiar and had its share of surprises.
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.
Roughly below the parking lot for the Rose Garden.
