Gardiner Tillamook Oregon Coast Steamer Sue H. Elmore 1908 Real Photo Postcard

Steam dredges, such as the vessel prominently featured with its large exhaust and associated pipe, were integral to maritime infrastructure development during the early 20th century. These powerful steam-powered vessels were specifically designed for excavation, removing sediment, sand, and other material from the bottoms of rivers, harbors, and canals. The visible pipe indicates a hydraulic dredging process, where excavated material is pumped over a considerable distance, often to a disposal area or for land reclamation.
