The top of Dock 4 was too dangerous to explore, but this panorama gives you an idea of the view (and how rotten the wood was).
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.
This skyway, built to help seal off two parts of the complex during an out of control fire, was probably too rotten to burn by the time I saw it.
Ultimately, it was the bad roof that doomed these buildings.
It seems logical that, at one time, a rock crusher was installed at the base of the mine rails shown here at the top of the Concentrator. Rocks small enough to fit between the rails would automatically bypass the crusher and continue to the work floor via the hopper below.
Snow weight collapsed this warhead assembly building. Now its warped roof looks like a wave.
The elevator works on gravity… this is where a conveyor belt was to move the grain toward the main elevator to be loaded into ships.
Happy mine bacteria ‘chews’ away at one of the narrow gauge rail ties still embedded in the sand floor. The orange color is not a mistake of mine; it is the result of different minerals leeching into the water table and draining into the mine. Keep in mind that, about 100 feet above, is the Ford plant itself!
