 The Slip Point Light was constructed to fill the gap between the Cape Flattery and Ediz Hook lights.Funds appropriated in 1900 were insufficient to complete the station as planned, so the first light was simply a lantern hung on the front of the building housing the fog signal.This was first lit in September 1905; in 1916, a short square tower was built on the side of the building, its lantern housing a fourth-order clamshell Fresnel lens visible from the Canadian shore.
