Two North American tribes successfully developed impressive trade networks that covered most of the continent during the two earlier time periods. Identify these two Native American tribes.

Adena and Hopewell

Explanation:

The ancient Adena Culture of Kentucky and surrounding states is renowned for its massive burial mounds and exquisite art works. But the lives of Adena people are shrouded in mystery because only three habitation sites have been found. Where did they live? Apparently, modern farming has destroyed most of their archaeological traces.

DescriptionThe Hopewell tradition describes the common aspects of the Native American culture that flourished along rivers in the northeastern and midwestern Eastern Woodlands from 100 BCE to 500 CE, in the Middle Woodland period.
