Tree Point Light

Tree Point Light stands beside Revillagigedo Channel near the southernmost point of mainland Alaska and was built to guide shipping through Southeast Alaska’s coastal waters. It was the first and only lighthouse constructed on mainland Alaska, with the station approved in 1903 and activated in 1904. Rebuilt in reinforced concrete between 1933 and 1935, the surviving main light and fog-signal building was designed for the site’s exposed conditions and originally used a fourth-order Fresnel lens. Automated in 1969 and altered again in 1977, the station still retains an unusually intact complex that shows how remote navigation aids once operated in the region.
