Starting in the mid-19th century, Coos Bay had become an important shipping point on the west coast of the United States.

This tower, located on the west end of an island, was connected to the keeper's residence via a 1,300-foot (400 m) wooden walkway.

However, because of its location on the island, the light was greatly exposed to the elements along the Pacific and soon was in need of repairs.

Located higher on the island, the new wooden tower stood 100 feet (30 m) tall and provided better illumination.
