The village of Mapusaga was almost entirely displaced during World War II in favor of military installations. It was the location of the U.S. Navy operated Mobile Base Hospital. Mapusaga has been called "Mormon Valley", as the Church of Jesus Christ of Latter-day Saints previously was based here. The Mormons constructed Mapusaga High School in 1928, which was located at the current location of American Samoa Community College (ASCC).

Olotele Mountain is divided between the villages of Mapusagafou (bottom half) and Aoloau (top half).
