Crossing+the+Plains+kc09

As Lewis and Clark were traveling up the Missouri River to the lands of the Mandan and the Sioux, they depended a lot on the goodwill and help of the Indians they met. Some of the most important help came from Sacagawea, the wife of a French fur trader, who offered to help Lewis and Clark as they crossed the plains. As they crossed the plains Lewis kept a Journal of all the things he expirienced.
