Red Rock Island (variously known as Moleta,[1] Molate Rock,[2] and Golden Rock[2]) is an uninhabited, 5.8-acre (2.3 ha) island in the San Francisco Bay located just south of the Richmond–San Rafael Bridge.[3] The property is the only privately owned island in San Francisco Bay.[3] The boundaries of three counties – San Francisco, Marin, and Contra Costa – converge on the island.[4] The Contra Costa portion (most of the island) is incorporated inside the city limits of Richmond.[5]

The mountain of bright red earth and rock is 500 ft (150 m) across from east to west, 750 ft (230 m) from north to south, and rises out of the bay to a height of 151 ft (46 m).[1] It is surrounded by some of the deepest water in the North Bay, nearly 60 ft (18 m) deep.
