The picture I want to see is the backing of the loaded dump truck up the coal pile on planks. I missed taking a picture of it on my first trip to Superior. I was too dumb to know what they were telling my to take a picture of. Maybe next summer. I don't know if it's a common practice but at Superior the summer coal pile grows and grows by dumping more and more coal on top. Accomplished by backing a dump truck up the pile! I think they are nuts to do this, but I guess the planks distribute the weight enough that it's possible.
