North Head Lighthouse, Washington

The Cape Disappointment Lighthouse was a disappointment because it was obscured to ships approaching from the north by the headland extending southwest from the light. To solve this problem, a lighthouse was built at North Head, which faces the ocean directly and would be clearly visible to ships traveling from the north. The 65-foot (20 m) tower stood on a 130-foot (40 m) cliff. The lens was the first-order Fresnel lens from Cape Disappointment that was first lit in 1898.         
                                                                                       
In 1935, the first-order Fresnel lens was replaced by a fourth-order lens. That lens was. eventually replaced by an aerobeacon in the 1950s, and later by a modern optic mounted outside the tower. The light was automated in 1961. This lighthouse, as well as the Cape Disappointment lighthouse, is part of Cape Disappointment State Park.
