That is the old Gates plant in Denver.  A friend of mine spent 6 months hauling stuff out of there to ship to...wherever.  He thought he could get me in to that old building but his bud wasn't in the right booth.  So we waited until golden hour to take those shots.  If I had turned the camera around, I could have shot a spectacular sunset on the Rockies.
