Sears Rock (sometimes Sear's Rock) is a small sub-surface rock about 0.7 miles (1.1 km) west of Rodeo Beach in the Pacific Ocean off Marin County, California.[2] It is the highest point of the larger Centissima Reef, a sub-surface navigation hazard east of the Bonita Channel, although some reports refer to the two as separate features.
A 1908 report on San Francisco Bay stated that a survey was then in progress to investigate the cost of removing both Sears Rock and Centissima Reef, along with and , near in San Francisco Bay.[3] In 1922, Representative Julius Kahn told a congressional committee that neither Sears Rock nor Centissima posed a navigation hazard as they had been blasted several years previously: "They are not visible, neither of them. The Sear's was blasted to a depth of 40 feet some five or six years ago. It is never visible at all. There are some people who think that it ought to be blasted to a depth of 45 feet, but the men who navigate the vessels think 40 feet for the present time a sufficient depth."[4]
