Ancient Idaho culture timeline, 6000 BCE to 3000 BCE
Idaho Indian tribes say they have occupied their homelands since time immemorial. The state of Idaho has a cultural history spanning at least 6,000 years that has been proven with modern archeology techniques.
This state spans two cultural areas: the Plateau Region in the north and the Great Basin Region in the south. Climate changes from 6000 BCE to 3000 BCE affected the original American Indian people in these two areas differently. This is called the Middle Period by archaeologists. Here is a timeline of the changes that occurred in this area.
