Observation Post, Fort Warden
Looking across the top of the old gun battery at Fort Warden, near Port Townsend at the inner end of the Strait of Juan de Fuca. It once had two 12-inch guns, one of them in a pit barely visible to the right of the skateboarder. I know of at least three other similar forts in the area. None were ever in combat. Perhaps that means they did their job.
