The Superior Express -

The arrow points to the same structure in both pictures. Above, the normally crisp, clean air lets one see the structures Superior - especially the elevators: Holcim, Aurora Cooperative and Agrex.

The pictures were taken within 50 yards of one another from the hill south of Superior known as Blauvelt's Hill.
