It was another beautiful day here in the UP. Last nights low was 60 and today' high was a mostly sunny 75. A light breeze made a long sleeve shirt feel good when sitting in the shade.
I am fascinated by the ore docks. Back in the early 70's, when I worked for American Bridge Division of US Steel, I went to their ore loading facility in Two Harbors, MN, in February, to look at a potential project. The day we were there the weather was nice, for Feb next to Lake Superior. A tug boat spent 24 hours a day moving around in the harbor, to keep the ice broken up. It only came in to the docks long enough for more fuel and supplies.
I went to the active ore dock both of the previous times we have been here, but basically just drove by them. Yesterday I found an app that told me that during the middle of the night a freighter was coming in to be loaded with ore. A 2nd freighter was supposed to come in at 12:30PM today. Another app I have made me thing that the 2nd freighter would arrive much later than 12:30PM. Kathy told me to go watch them and she stayed home. I was out there at noon.
The Joseph L Block was still being loaded. She is a self-unloader bulk carrier. She is 714' long and 78' wide. She had a cargo capacity of 37,200 tons. Her aft mounted unloading boom is 250' long, I don't know why it was sticking out to the side today. She was built in 1978.
I walked around trying to get a better photo. The ore dock, on the left side of the photo below, is lined with chutes that lower to discharge taconite (iron ore pellets) into the ships holds. The are huge bins that feed the chutes through hydraulic gates. On top of the ore docks are at least two sets of rails that allow cars to be pushed out onto the dock and discharge into the bins.
Later, apparently when she was closer to being full, the boom was swung back over the ship, but not yet lowered to the deck, where it is normally stored.
When I was walking to the other side of the dock a pair of engines pushed loaded cars onto the dock. I didn't see them in time to count the cars going up but after some switching I counted 47 empty cars being pulled off the dock.
The other side of the dock.
Around 2:30PM I watched the Lee A Tregurtha, in the photo below, make her way around the end of the breakwater and I thought turn towards the dock. Instead she turned completely around and headed back into Lake Superior. I have no idea why. Shortly thereafter she is supposed to have come back in and docked.
The Lee A Tregurtha started out as a WWII oil tanker. She is one of the most modified ships on the Great Lakes. She currently has a length of 730' and is 75' wide. She has a 22,500 ton cargo capacity.
