A foaga is a grinding stone and this one, located in a river bed in Moamoa, is the largest in Samoa. Featuring 15 distinct facets, the Moamoa Foaga’s period of use dates roughly to about 500-800 years ago. While a number of archaeologists discuss the possibility of a stone adze quarry in the Moamoa area, there are no records published on this particular stone. It may well have been obscured by foliage and eroding river banks for decades, until 19 June 2013, when Dicky Nansen, a local living in the area came across it in the aftermath of Hurricane Evan. Nansen reported his discovery to the Savali newspaper, who then alerted CSS. An initial report was conducted by Dr. Ethan Cochrane of Auckland University.
