The people living here gathered food and resources for tools and building. Other materials were obtained through trade. Trees nearby provided wood for posts for house walls and stockades, bows and arrow shafts, and firewood. Smaller tree branches and grass were used for bedding and roofs. Shells were used to make jewelry, beads, spoons, and digging tools. The people dug river clay to use in fashioning fired pottery. Traded items, used for ornamental or ceremonial purposes, were an attribute of status because of their rarity.
