Fun Fact Coincidence Friday. Jeff And I Were Just Discussing Isle Royale Transportation The Day Before I Started Reviewing This Stuff. Posted on March 24, 2017 by srcmtp The S.S. Seminole was a 188′ steel steamer built for the Coast Guard in 1899. It was repurposed as a passenger vessel during the Great Depression, and staffed as part of a public works program. Operating out of Houghton, it provided service to Isle Royale and Marquette. This photo from a collection of materials I purchased from the estate of Hazel Smith, who was an amateur photographer. I believe this was taken in the early 1940’s. Still looking for info on the fate of this ship.
