What was the Indians trade?

Answer 1

Horses made it possible to trade more bulky and valuable items, such as buffalo robes, dried berries, and root cakes. Smaller items included stone pipes, tobacco, Indian hemp, and dressed skins. Plateau tribes participated in great inner-tribal gatherings at the Dalles. There they traded items such as furs, roots, pemmican (smashed meat and berries), feathers, clothing and horses. These items were transported north to the Okanogan, Sanpoil, and other tribes of the upper Columbia.
