Lewis and Clark Memorial Column

The Lewis and Clark Memorial Column is a granite structure that rises approximately 34 feet tall with a sphere crowning its top. It sits in Washington Park and is surrounded by an illuminated pathway, making it easy to locate among the park's other features.

President Theodore Roosevelt laid the cornerstone in 1903, and the monument was completed five years later in 1908. The project was funded by the Lewis & Clark Exposition Commission, which supported this tribute to the historic exploration.

The four bronze state seals at the base show Oregon, Washington, Idaho, and Montana, all connected to the land the Lewis and Clark expedition crossed. Visitors can see how the journey touched many different regions and shaped their identity.

The monument is easy to reach via the illuminated pathway in Washington Park and sits close to other popular spots like the Japanese Garden and Zoo. Visit during daylight hours when the light best reveals the details of the granite and bronze seals.

The monument received recognition from the Smithsonian's Save Outdoor Sculpture program in 1993 for being well maintained. This acknowledgment highlights how outdoor structures like this one need ongoing care to survive the elements.
