Johnston Atoll is a 130 km² atoll in the North Pacific Ocean at United States Pacific Island Wildlife Refuges from The World Factbook, about one-third of the way from Hawai'i to the Marshall Islands. There are four islands located on the coral reef platform, two natural islands, Johnston Island and Sand Island, which have been expanded by coral dredging, as well as North Island (Akau) and East Island (Hikina), artificial islands formed from coral dredging. The four islands comprise a total land mass of 2.6 km². Due to the atoll's tilt, much of the reef on the southeast portion has subsided. But even though it does not have an encircling reef crest, the reef crest on the northwest portion of the atoll does provide for a shallow lagoon, with depths ranging from 3-10 m.
Johnston is an unincorporated territory of the United States, part of the United States Minor Outlying Islands, administered by the U.S. Fish and Wildlife Service of the Department of the Interior] as part of the United States Pacific Island Wildlife Refuges.
Its climate is tropical but generally dry. Consistent northeast trade winds have little seasonal temperature variation. With elevation ranging from sea level to 5 m at Summit Peak, the islands contain some low-growing vegetation on mostly flat terrain and no natural fresh water resources.
