Aʻumi is a village on the central south coast of Tutuila Island, American Samoa.
It is located to the east of Pago Pago Harbor and west of Alega.
Fatutoʻaga Rock (Pyramid Rock) is an islet which lies outside Lauliʻi near Aumi.[1] Eastbound buses from Downtown Pago Pago go to the beaches near Pyramid Rock.[2] Pyramid Rock is a prominent islet located just over one mile east of Breakers Point Naval Guns. Rising to a height of 89 feet, it is notable for its geological significance and serves as an important site for studying volcanic activity in the region. Pyramid Rock is recognized for its exposed dikes, which are geological formations created by the intrusion of magma into pre-existing rock layers. These dikes, often short, pod-shaped, or lenticular, resemble those found in the high cliffs of Olosega. Historically, Pyramid Rock was the site of a lighthouse, though its current status is unclear. It is one of several key locations in American Samoa, including Pago Pago, Fagaʻitua, Amouli, and Afono Bays, that offer valuable insights into the volcanic history and geological evolution of the islands.[3]
