Bldg 100 Some sort of materials handling building, judging by the construction. Similar Images ...based on the tags: black&white, clouds, numbers, overgrown, signs, trains... The Engine House’s boiler, which would have been fired all day all day, virtually from the day the shop opened until the day it closed. Looking out of the demolished skyway. Note the big hole in the floor. The lens is too wide to keep my foot out of it… I’m hanging in the superstructure that I climbed to make this photo. I found a meth lab in this building once. (Yes, I called it in.) Some of the internal staircases were fitted with cages that wound round down the stairs to deter suicidal patients from taking a dive. National Mine and its rockhouse (?) as seen from Mammoth Hill. From this angle, I am fairly certain this was a crushing and sorting house. The bottom looks like it has two aerial tram doors as well. One of my favorite photos of the ADM-Delmar #1 skyway, when it stood. Taken at sunset, with the reflection of the overcast sky in the remaining windows. The curving corridors flanking the Administration Tower are especially ornate, though the prison-like door betrays the real purpose of the building. One of the last times I saw the skyway standing. ADM’s Meal Elevator is in the distance. Colleen on the roof.
