At the south end of the Promenade stands a bronze sculpture by local artist Stanley Wanlass depicting Lewis, Clark, and their dog Seaman — the Newfoundland who accompanied the Corps of Discovery the entire length of the journey. The piece is called "End of the Trail" and it marks the approximate spot where the expedition, after 18 months of travel from Missouri, stood at the edge of the Pacific Ocean in November 1805. Clark wrote in his journal that the men were wet, cold, and in good spirits.
The monument is modest by the standards of national historical sites, which suits Seaside. This is a working beach town, not a shrine. But the location has genuine historical weight, and the surrounding boardwalk and candy shops make it feel accessible rather than solemn. Worth five minutes of your time at minimum.
