Cupola’s Worst Days A collapsing and unstable building. Similar Images ...based on the tags: collapsing, power, rusty, smokestacks, trestles... These machines are at least 100 years old. The elevator tower seems to have been built with expansion of the dock in mind. In case power was lost, this manual signal could direct trains on and off the taconite trestle. Turning the pole would change the color of the light on top and the shape of the metal flags. Standing next to the now-demolished records room. The gold mine is now a gravel pit. A ship passes the abandoned dock on its way to Duluth. Taconite dust stains the sides of its hull red. The ’59’ is just a reference to that work station.

Perhaps there used to be a building here that covered the entrance to the Santiago Tunnel… I wonder what this guy is thinking, walking through the complex.
