Plains
These sources focus on Mandan, Hidatsa, and Arikara village societies along the Missouri and Knife Rivers. They show that Plains life before European arrival included farming towns, earthlodges, long-distance trade, and complex social organizations.
Start with the overview
Use the Khan Academy overview for the broad region, then compare it with the more specific Knife River sources.
