About this visit:
They arrived Duluth May 28 2024 at 05:20 with a cargo of Limestone from Calcite MI for the Hallett Dock # 5. After finishing discharging the stone they did a dock shift at 12:45 and began loading Blast Furnace Trim (un-refined taconite rock). They Departed Duluth May 29, at 07:20 in the morning, making me a little late for work...
Well worth the time though, not too often you get such calm waters!
