Rose Atoll

Rose Atoll, sometimes called Rose Island or Motu O Manu by people of the nearby Manu'a Islands, is an oceanic atoll within the U.S. territory of American Samoa. It is an uninhabited wildlife refuge. It is the southernmost point in the United States. The land area is 0.214 km² (52.8 acres). The total area of the atoll, including lagoon and reef flat amounts to 5 km². Just west of the northernmost point is a channel into the lagoon, about 40 meters wide. There are two islets on the northwestern rim of the reef, larger Rose Island in the east (3.5 m high) and the non-vegetated Sand Island in the north (1.5 m high).

The first documented sighting by a Westerner was by Louis de Freycinet in 1819. He named it after his wife Rose. While the second woman to circumnavigate the globe, Rose de Freycinet was the first to tell her tale. In his official report Louis deFreycinet records that 'I named Rose Island, from the name of someone who is extremely dear to me'. Soon afterwards, in 1824, it was seen by the expedition under Otto von Kotzebue, who named it Kordinkov after his First Lieutenant.

The Rose Atoll Marine National Monument that lies on the two outstanding islands of the Atoll is managed cooperatively between the U.S. Fish and Wildlife Service and the government of American Samoa.
