This is a rather unique perspective of Enger Tower and Skyline. The buildings were level with one another, so one could look through as many as a dozen factory floors from one window. Between all of the buildings was dense growth, especially vines. A full harbor on a hot summer evening, just after twilight, as seen from atop the castle walls. The elevator near the offices seemed a day’s work away from being operational SFAAP’s iconic smokestacks. You’d notice if you drove past this on the highway. Wind took the spring melt on the trees growing in taconite pellets and made it airborne. Loading chutes in the background. From the bottom of the skyway I looked back, my eyes tracing the vines from the marsh up the smokestacks to the perfect Midwestern sky. My first picture at Nopeming, sometime around 2004. The same year that the county stopped mowing the lawn.
