    The Corps of Discovery Camp up river in Council Bluffs, Iowa. Then after five days, some Oto and Missouri chiefs, some warriors, and French arrive. They all have a small meeting and promise each other peace and future trading. This date is important because these are the first Native Americans that The Corps Discovery see on the way and they are trying to make as many Native friends as possible.
  • South Dakota

    South Dakota
    While Lewis and Clark were in South Dakota, they discovered a plant they named a prairie turnip. This plant had a starchy root and it could be eaten like a potato. This plant could also be pounded into a flour and made into bread. Lewis and Clark had never seen such a plant before and it was important for them to record this in their journals.

    Lewis, Clark, and the rest of the men reach Nebraska and they spot many animals that they had never seen before such as coyotes, antelope, mule deer, and others.
