In Arizona one example is the Hohokam: https://en.wikipedia.org/wiki/Hohokam

They built canals for farming and understood how to use wild plants. Other cultures ( Akimel Oʼodham for one) are also interesting to read about how they lived.

Hohokam and the O'odham are related in much the same way the US is related to the British empire. One descends from the other.
