The historic steam tug Portland, a 1947 sternwheeler based in Portland, Oregon, United States, is listed on the U.S. National Register of Historic Places (NRHP). It serves as the home of the Oregon Maritime Museum, but is fully operable and occasionally makes excursions. It is pictured arriving back in Portland at the end of a cruise to St. Helens, Oregon, and has just passed under the 100-year-old Steel Bridge. The Rose Garden arena is partially visible in the background.
