Lake Mungo find more evidence for the "out of Africa" theory. The rich archaeological heritage of the site is very significant to the Aboriginal Australian people from the area. The Willandra region is inhabited by the Barkindji, Nyiampaa and Mutthi Mutthi peoples, who have now entered Joint Management Agreements with the Government of New South Wales to manage the lake and the Mungo National Park. In 1972, Archaeomagnetic studies were conducted on the prehistoric aboriginal fireplaces occurring along the ancient shoreline of Lake Mungo. Magnetization preserved in oven-stones and baked hearths show that the axial dipole field moved up to 120 degrees
Lake Mungo Lake Mungo results were due to thermoremanent magnetization, ruling out a sedimentological phenomenon. Two excursions have been recorded in sediments from Skjonghelleren on Valderøy, Norway with the Virtual Geomagnetic Pole (VGP) of one being synchronous with Lake Mungo suggests that the Lake Mungo event was global rather than a local event. Data from lake sediments of a similar age in France having near identical magnetic field lines also support Lake Mungo being a global event. However, it has been suggested that Lake Mungo's anomalous field is the result of lightning strikes. Lake Mungo Lake Mungo is a dry lake located
