Partier graffiti dates to when the caves were last open to the public; probably in the 1990s. This tunnel used to horseshoe between the brewery’s ice chute (left) and basement door (right, backfilled). Note the utility tunnel in the upper-right corner as well as the lighting brackets on the ceiling.
When the ship loaders were added, a doorway was cut through the metal silo to make a room for the grain handling equipment. Note the dust sensor in the corner of the torch-cut archway.
