Smoothened Stairs The side stairs were worn smooth by use. Similar Images ...based on the tags: archways, brickwork, brown, staircases... The Osborn Block (front) and the Twohy (rear) at sunset. In the distance, you can almost make out Globe Elevators. One of my favorite photos of 2013. On my first visit to the roundhouse, the control booth was extant. Looking at the entrance of the powerplant from its lowest catwalk. Chicago looks in as we look out, for holes and trolls where anything goes. The substation has definite structural issues. Pictured is the sidewalk that connected the plant to the company housing. Jet Lowe is my inspiration. This is a great example of a combination rock house; the silos below used to fill trains with ore dropped from mine cars pulled to the top of the structure. Although the caves deviated little in their year-round temperature, it was common to use blocks of ice to cool beer immediately before shipment. This is the ruins of the ice chute. I wonder if these windows were bricked after the 1950 explosion with the hopes that, if another silos blew, the people in this office would be better protected.
