Point Conception, Gaviota Coast

Point Conception, Gaviota Coast

by | Aug 3, 2021

Point Conception is located on the Gaviota Coast, at the western end of the Santa Barbara Channel, about 45 miles (72 km) west of Santa Barbara and 13 miles (21 km) south of Lompoc, California. The double headlands of Point Conception and Point Arguello, which are about 14 miles (23 km) apart, create a natural division between the Central California coast and the Southern California Bight. This region has been inhabited since the Paleoindian Period, 13,000 to 8,500 years ago, and at least 14 Chumash villages were located along the coastline. The Chumash people have traditionally known this headland as the “Western Gate”. The first sighting of Point Conception by a European was on October 18, 1542, by the Spanish explorer Juan Rodriguez Cabrillo. He encountered high winds while rounding the point and was driven across the Santa Barbara Channel to San Miguel Island. In 1602, Sebastian Vizcaíno sailed past the cape and named it Punta de la Limpia Concepcion. The Spanish began colonizing Alta California following the Portolá expedition of 1769–1770. In 1837, a Mexican land grant of 24,992 acres (10,114 ha) called Rancho Punta de la Concepcion, from the secularized holdings of Mission La Purísima Concepción, was given by Governor Juan Alvarado to Anastasio José Carrillo. The grant was situated along the Pacific coast from Point Arguello south to Cojo Creek, just east of Point Conception. In 1851, Carrillo partitioned the property into Rancho La Espada (the sword) with 16,500 acres (6,677 ha) on the west and Rancho El Cojo (Ranch of the Lame) with 8,580 acres (3,472 ha) on the east. In 1851, Carrillo sold the property to Isaac J. Sparks, and 1852, Sparks sold it to Gaspar Oreña, who sold it to Thomas Dibblee in 1867. In 1879, the Dibblee-Hollister partnership was dissolved, and Rancho La Espada went to Hollister, and in 1883, it was sold to Captain Robert Sudden. In 1876, Carrillo was sold Rancho El Cojo to General P.W. Murphy. Murphy believed that Cojo would be a major port after the arrival of the Southern Pacific Railroad, but the railroad did not reach Point Conception until 1899, and Murphy would lose Rancho El Cojo through bank foreclosure. Rancho El Cojo and the adjacent Jalama Ranch were owned by the Bixby Ranch Company until 2007. The Gaviota Coast is still a rural coastline and is considered the last undeveloped stretch of Southern California. In December 2017, The Nature Conservancy purchased the expansive Cojo Jalama Ranches surrounding Point Conception with a donation from Jack and Laura Dangermond, and the property will be known as the Jack and Laura Dangermond Preserve.

The original light station at Point Conception was one of the earliest lighthouses built in California. The station was on a sandstone promontory 215 feet (66 m) above the ocean. Construction began in 1854, with supplies freighted down the coast from San Francisco and then off-loaded through the surf at Cojo Landing located just east of the point. From the beach, the construction materials were hauled uphill by ox-drawn wagons. The original lighthouse was a single-story dwelling featuring a tower rising through the center similar to the structure at Point Loma. The tower lantern room was designed to house an Argand lamp and reflector, but by the time this was completed, the U.S. Lighthouse Board ordered the installation of a first-order Henry-Lepaute Fresnel lens. The light was finally activated on February 1, 1856, and the Point Conception Lighthouse became the seventh operating lighthouse on the U.S. west coast. In 1881, the lighthouse was moved to a lower elevation of 133 feet (41 m) above sea level because severe fog was less likely to obscure the light, In May 1882, a fourth-order Fresnel lens was installed. In 1948, the station was electrified and the oil lamps were removed. The light station was automated in 1973, ending 117 years of manned operations.

The weather at Point Conception is often windy, especially in the winter when winds are predominantly from the southeast through the Santa Barbara Channel. These gale-force winds were experienced by Cabrillo in 1542 and well documented by Richard Henry Dana in 1840 on Pilgrim, a sailing brig of 86.5 feet (26.4 m) overall length. The point is also known for unusual waves even in calm weather. On November 4, 2000, the Channel Islands National Marine Sanctuary research vessel Ballena of 56 feet (17 m) overall length, capsized in a rogue wave north of Point Conception. The vessel was working for the U. S. Geological Survey and engaged in a routine side-scan sonar survey of the seafloor along the 30-foot (10 m) depth contour approximately 0.25 nautical miles (0.5 km) from the shore. The crew included the captain, National Oceanic and Atmospheric Administration Corps officer Lieutenant Commander Mark Pickett, Dr. Guy Cochrane, and assistant Mike Boyle. The weather was fair, with clear skies and swells of 5 to 7 feet (1.5 to 2 m) but calm winds. Pickett and Boyle said they observed a wave of about 15 feet (4.5 m) in height begin to break 100 feet (30 m) to seaward of the boat. The wave crested and caught Ballena broadside, breaking over and capsizing the vessel. Two crew members were briefly trapped inside but were able to find their way to the bridge doors and escape the overturned vessel and deploy the vessel’s liferaft. The crew attempted to paddle to the shore but realized that navigating the raft safely to shore was unlikely due to strong near-shore currents. The crew abandoned the liferaft approximately 150 feet (46 m) from shore and attempted to swim to safety. After reaching shore, Pickett swam back out to first assist Boyle to shore and again to assist Cochrane to shore. The crew then climbed the rocky cliffs along the shore and survived. The vessel broke apart in the waves against the rocky shore and was a total loss. Read more here and here. Explore more of Point Conception here:

About the background graphic

This ‘warming stripe’ graphic is a visual representation of the change in global temperature from 1850 (top) to 2021 (bottom). Each stripe represents the average global temperature for one year. The average temperature from 1971-2000 is set as the boundary between blue and red. The color scale goes from -0.7°C to +0.7°C. The data are from the UK Met Office HadCRUT4.6 dataset.
