Description: A tinted photographic postcard. At the top in red is the legend "Cascade Locks, Columbia River". A steamship is shown going into the locks. Passengers or crew can be seen on its three decks; along both sides of the locks are small groups of men and women watching its passage. The water is calm; it is a dry sunny day with puffy clouds. A lawn stretches off to the left of the photograph. Across the river from the locks forested hills rise up.

Description: A tinted photographic postcard. The caption at the top reads "Steamer Dalles City, D. P. & A. Nav. Co., in Cascade Locks, Columbia River." The paddlewheel of the Dalles City is clearly seen as the ship makes her way towards the lock. A few people are visible on the deck of the boat, and others are along both sides of the canal. A series of stairs follows the water. On the near side of the canal a beached rowboat is tied up, and the area is strewn with rocks. Beyond the locks is the roof of a building. In the distance are forested hills and mountains.

Description: A black and white view of the Cascade Locks on the Columbia River, approaching from the west. The locks were completed in 1896 and submerged in 1938 with the completion of the Bonneville Dam. In the photograph, the lock gates are closed. A town is visible in the distance on the heavily wooded far bank of the river, and small wooded islands and some rocks are also seen in the water. To the right of the picture are several light-colored wooden houses, which all appear to be multi-storied. To the right of the houses runs the highway. In the distance rise the forested hills and moutains.

Description: A black and white view of three steamboats in the water approaching Cascade Locks on the Columbia River. The paddlewheel of the large stern wheeler to the left of the photo can be clearly seen. This ship is much larger than the other two at right, and has been identified as the "Bailey Gatzert". One of the other steamers has been identified as the "Charles R. Spencer". Their smokestacks all belch smoke. In the river some small islands can be seen. On the further shore, a low, well-forested riverbank with a settlement of houses rises to wooded hills. To the center right of the picture the locks are seen. The Cascade Locks were completed in 1896, and submerged in 1938 as a result of the construction of the Bonneville Dam.
