Near this point, sea and land parties of the Portolá-Serra expedition met. Two ships, the San Antonio and San Carlos, anchored on May 4-5, 1769. The scurvy-weakened survivors of the voyage established a camp, where on May 14 and July 1 they greeted the overland parties from Baja California. Together, they began the Spanish occupation of Alta California.
