More About Copper
Did people interact with their neighbors? What kinds of goods were exchanged? Archaeologists can identify the sources of many materials, and when these materials are found in distant places, we know that trade or travel must have been involved. We know that traders and travelers from earliest times brought items from far away. These included many different kinds of raw materials for stone tools, as well as marine shell and copper made into items that may have represented valued ornaments or personal items. Although we know of only the durable materials, other items such as feathers, hides and food were probably also widely traded.

Some materials were traded very widely, such as copper and marine shells.
