The natives of this region derive their crops from the more advanced civilization to the south, in Mexico. The same cultural influence brings a custom eventually shared by many of the tribes, that of mound building. From about 1000 BC great burial mounds begin to be constructed around tomb chambers of log or wood.

The earliest burial mounds in North America are those of the Adena culture of the Ohio valley, closely followed by nearby Hopewell tribes. The period of greatest activity is from the 1st century BC to the 5th century AD, by which time a vast number of mounds have been built throughout north America.
