The station's first light was a lens lantern displayed from a post located close to the point. A steam-powered Daboll trumpet served as the fog signal.[4] In 1936, a square concrete tower was added to the site with a {{convert|300|mm|disp=flip|adj=on}} light emanating at a {{convert|44|feet|adj=on}} focal plane.[5] A diaphragm foghorn replaced the Daboll trumpet. The station was automated in 1974.[4] The station is owned by the U.S. Coast Guard and managed by the U.S. Bureau of Land Management. It is part of the San Juan Islands National Monument, which was created in 2013.[7] Volunteers through the Turn Point Lighthouse Preservation Society[2] offer seasonal docent guided tours of the original 1893 Keepers House and a first class exhibit of historic photos.
