Interesting thread and great models. The ship in the first post is actually the combined tug/barge unit shown here: http://www.americansteamship.c...-lakes-contender.php
All the ore from Lake Superior goes to steel mills in the lower lakes, e.g. Burns Harbor IN and other destinations. There are actually American flag ships "trapped" on the upper lakes due to their length and single-purpose of ore carrying on these dedicated routes. Other great places to see lakers and salties up close are Duluth (as mentioned) and Two Harbors MN. You will also be in the immediate vicinity of three 2-8-8-4 Yellowstones on display.
