Shown here are different images over time of the 4th order Fresnel lens that was once in use at the long lost Semiahmoo Harbor Lighthouse near Blaine, Washington.
A number of years later, the late Jim Gibbs, noted maritime author and historian, who was also a former lighthouse keeper, found the lens in a scrap heap and secured it. It is now in the Jim Gibbs Collection in Yachats, Oregon.
