Many of the higher floors were more or less demolished–usually more. These would have been condos had ‘The Arcade’ project come to fruition. Now there are simply wide open floors punctuated only by pillars and meaningless hallways.
The guts of the dock are connected with a long narrow hallway. Below this section are shops and labs.
The top floor of the nitrating house was full of switches and breakers for the operation below, each bearing a label and number. Nowadays everything is printed, but when INAAP was built, all these signs were painted by hand.
The big door at the bottom of the concentrator was where a tram once connected to lower the (pre-) processed ore into the river valley, where the railroad was. It’s unclear whether this ever connected directly to Eureka’s Sunnyside mill, although it’s possible.
These wide spools sit atop the abandoned tracks that lead to the train shed, which was later repurposed into a truck shed.
One of the storage bunkers was cracked open. I wonder how effective this heavy door would actually be… I expect, not very.
This building was 99 years old when it was demolished for the coal mine.
An old nurse’s station (you can tell because of the half-door with table) with torn-up tiles. Notice through the curved doorway that even the ceiling has a curvature.
Looking into the Argo Tunnel at its Idaho Springs portal. I was hoping to see tracks and a steel door, but found a busy crew of environmental workers installing a pipe between the bulkhead and new water plant.
