- Description:
- The Duluth Missabe and Iron Range ore docks are the two reddish brown linear structures in the foreground. Ore boats are pulled between the docks by tugboats. Railroad cars loaded with ore or taconite pellets move along the railroad tracks on the top or the length of the dock. A chute or steel pocket beneath the tracks is lowered to the open cargo hatch and a door at the bottom of the pocket opens, allowing the pellets to run into the ore boat that moored parallel to the dock. Four hours is typical for loading ore. Loading is the responsibility of the First Mate. It is important to load the ore in a proper sequence to avoid over stressing the boat unevenly. Each chute (or drop of pellets) is about 20 tons.
