Woodland people invent pottery for food storage and cooking and the bow and arrow for hunting and protection. They live in small villages, and they require raw materials and finished objects through long-distance trade. They bury their dead in mounds built on bluff crests overlooking streams. They build mounds by adding earth, one basket load at a time. Woodland people made the mounds in Indian Mounds Park. Woodland trade provides many exotic materials including marine shell, obsidian (volcanic glass), mica, sharks' teeth, rock crystal, and copper. Copper is used to make objects such as this celt, an axe-like tool.
