Although little archaeological excavation has been done in Enga, it is clear that the area has been settled for over 12,000 years. Europeans—typically Australian gold prospectors—originally entered what is now Enga province from the east in the late 1920s, although the best-known exploration of Enga took place during the early 1930s when Mick Leahy and a party of men travelled from what later became Mount Hagen to the site of the future Wabag and then south through the Ambum Valley to what later became East Sepik.
