Rose Atoll National Wildlife Refuge

Rose Atoll, sometimes called Rose Island or Motu O Manu by people of the Manu'a Islands, is an oceanic atoll within the U.S. territory of American Samoa. An uninhabited wildlife refuge, it is the southernmost point belonging to the United States, about 170 miles to the east of Tutuila, the principal island of American Samoa. The land area is just 0.05 km2 at high tide. The total area of the atoll, including lagoon and reef flat amounts to 6.33 km2. Just west of the northernmost point is a channel into the lagoon, about 80 metres (260 ft) wide. There are two islets on the northeastern rim of the reef, larger Rose Island, 3.5 metres (11 ft) high, in the east and the non-vegetated Sand Island, 1.5 metres (5 ft) high, in the north.
