    Overview

    The Gardner Pinnacles (Hawaiian: Pūhāhonu) are two barren rock outcrops surrounded by a reef and located in the Northwestern Hawaiian Islands. The large and small rocks have been named ʻŌnūnui and ʻŌnūiki, respectively. The Pūhāhonu volcano responsible for the pinnacles is 511 nautical miles (946 km; 588 mi) northwest of Honolulu and 108 miles (94 nmi; 174 km) from French Frigate Shoals. The total area of the two small islets, remnants of an ancient shield volcano, the world's largest, is 5.939 acres (24,030 m2). The highest peak is 170 feet (52 meters). The surrounding reef has an area in excess of 1,904 square kilometres (470,000 acres; 735 sq mi). The Gardner Pinnacles were discovered and named in 1820 by the whaling ship Maro. The island may be the last remnant of one of the largest volcanoes on Earth. It holds the record for the largest and hottest shield volcano.
