Point Arguello Light serves a dangerous stretch of California’s Gaviota Coast near the western Santa Barbara Channel, where fog, reefs, and narrow approaches long made navigation hazardous. The point was earlier known to the Canalino Chumash as Nocto, visited by the Portolá expedition in 1769, and later named by George Vancouver in 1793 for José Darío Argüello. A lighthouse station built in 1901 was altered repeatedly because of erosion and changing needs. The area became notorious for shipwrecks, including the Yankee Blade, the Santa Rosa, and the 1923 Honda Point disaster. Beyond its beacon, the station also served lifeboat, wartime Coast Guard, radio navigation, and weather-reporting functions.
