TitleCascade Locks, Columbia River
DescriptionA 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.
