The growing story of early settlement in the northwest Pacific islands
is moving from coastal sites into the rainforest. Evidence of Pleisto
cene cultural layers have been discovered in open-site excavations at
Yombon, an area containing shifting hamlets, in West New Britain's int
erior tropical rainforest. These sites, the oldest in New Britain, may
presently stand as the oldest open sites discovered in rainforest any
where in the world.
