On the Great Plains. They lived mostly on the Black Hill. In the winter it would begin to get colder. So the Lakota would move into more protected areas such as the forest. But during the summer they would stay in the great plains hunting buffalo. Their main food. Sometimes it would be so dry during the summer fires would happen. That is why the plains did not have a lot of trees! I assure you this information I have just supplied you with is accurate. I have done a 20 pg. Report on the Lakota Sioux. I know what I am talking about. I will post more later!
The Lakota are the western-most of the three Sioux groups, occupying lands in both North and South Dakota.
