Visited Marquette in 1980, and stopped by the Soo Line's lower yard in town. It was loaded with wooden freight cars in MOW service and the real find, a couple of iron buckets being used to store retrieved scrap metal. These were the kind used in coal sheds, for fueling steam locomotives. I assume, every bit of that, including the lower yard, is gone.
Nice to see there is still some ore boat traffic remaining.
