It was built in 1901[4] or 1902[2] as a replacement for Point Adams Light. The Lightship Columbia kept station about 5 miles (8.0 km) offshore.
Its design by Carl Leick is identical to that of Semiahmoo Harbor Light near Blaine, Washington, a 1+1⁄2-story dwelling built on a cluster of pilings in 12 feet (3.7 m) of water[3] with a rooftop tower housing the light and a fog signal. It was one of the last U.S. wooden pile foundation lighthouses built.[5] A cistern system collected fresh water. Only the lightkeeper was present; there was a small boat to reach the mainland, where the keeper's family lived.[4]
The light was electrified in 1934, eliminating the need for a keeper. It was removed and replaced after World War II[5] by a minor aid on top of a pyramidal structure, which was replaced again in 1955. The light was removed in 1965.[4]
Desdemona Sands is a group of shoals formerly named Chinook Sands. In 1857, the bark Desdemona ran aground here and was destroyed.[4]
