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.

Beside the shaft building are two fans on skids, indicating they were used underground.
The spectacular, if precarious, view of downtown Minneapolis from the roof of ADM Annex 4. Note the great messages left by various graffiti artists who made it to the spot.
I wish I knew what has become of this great one-of-a-kind sign that used to brag how many days the Clyde Iron factory has gone without a serious accident. Update: It’s hanging in one of the smaller venue spaces behind the bar.
