Two Harbors - Iron Ore Docks

Here we are on the north shore of Lake Superior at Two Harbors. There
are three cool Iron Ore Docks on the bay to load taconite onto barges.
If you look closely, you can see a barge on the other side of the dock
behind me. They were first built of wood and then reinforced with
steel in the 1920's. The informational sign said 10,000,000 tons of
the iron ore are shipped out every year - wow! What a neat structure!
