 Evidence of an imposing palisade erected around one of the residential precincts at the site has been found, leading archaeologists to hypothesize about conflict and competition in the local Mumun society.A number of smaller settlements from the same time period are found within several kilometres of Songguk-ri.The site also contains a high status stone-cist burial with a Liaoning-style bronze dagger, a number of large tubular-shaped greenstone ornaments, and a finely-made groundstone dagger.
