Great Lakes C4 iron ore carriers converted from surplus World War II cargo ships: Part Two

After World War II there was a drastic need for steel and iron ore in the United States- there was also a huge amount of surplus ocean cargo ships. Most of that iron ore came by way of Great Lakes freighters. Since it would take over two years to build a new modern oreboat on the lakes, the concept was fetched to simply convert some of those surplus ocean cargo vessels into Great Lakes oreboats. This could be done in less than a year. The C-4 class of cargo vessels best fit the concept and the work began in 1951. Here in Part Two we'll see their activity and history on the Great Lakes.
