About
La Perouse Pinnacle is a steep basalt outcrop at French Frigate Shoals in the Pacific Ocean. Rising approximately 122 ft (37 m) above sea surface, it is the eroded plug of a shield volcano and caldera that formed 12 million years ago. The rocky formation lies within the Papahānaumokuākea Marine National Monument. Because of its prominence and shape, the pinnacle can be mistaken for a sailing ship from a distance.
