Historical Information:
- Construction began in the summer of 1903 but halted for the winter. The light was completed in lit by September 1904. Classified as a minor light it had a fixed white fourth order lens. This was one of only three stations in Alaska where families were permitted to live.
- Improvements were made in 1922 when a reinforced concrete fog-signal building replaced the bell struck every 20 seconds by clock work machinery. The original bell tower was also improved and heightened.
- In 1938-39 a radio telephone and a radio beacon monitoring system were installed.
- In 1956 the radio beacon was modified for both marine and aircraft navigation.
- Station was automated in 1969.
