This is the USS Chiwawa. It was a T3-S-A1 auxiliary oiler. After the war she was converted to a bulk carrier and continues to sail the Great Lakes to this day.
I took these photos last May of the ship. If you look at the bridge wing you can see the battle ribbons the ship earned during her career in WWII. They were added in 1999.
These are what the ribbons are:
Top Row: American Campaign Medal, Europe-Africa-Middle East Medal (1)
Bottom Row: Asiatic-Pacific Campaign Medal (1), World War II VictoryMedal, NavyOccupation Service Medal (with Asia clasp)
