This is a draft (I'll probably edit it in place) of what I'm working on to post to CFB before /u/hythloday1 puts up her long study. Please let me know if things don't make sense or I need to explain things in better ways.
Review and History. The Port of Minneapolis is the northernmost port on the Mississippi River System. Located near the convergence of the Mississippi and the Minnesota Rivers, the Port of Minneapolis is about 17 nautical miles upriver (20 kilometers or 12 miles northwest by air) of its sister city, St. Paul. Seat of Hennepin County, Minnesota, the Port of Minneapolis and St. Paul form the Twin Cities conurbation.
The Hesper was a bulk-freighter steamship that was used to tow schooner-barges on the Great Lakes. The Hesper sank off the coast of Lake Superior at Silver Bay, Minnesota, USA, in a late spring snowstorm in 1905. The remains of the ship are listed on the National Register of Historic Places.
