At this site in Nebraska, the expedition held its first council with Native Americans, a critical encounter with members of the Otto and Missouri tribes. Lewis and Clark knew that much depended on the outcome of this meeting. If it went well, news would travel quickly and the expedition was likely to be welcomed and assisted by other tribes met along the way. If the council went badly, the expedition most likely would not have support from the Native American population, and might have to face the journey without their aid and vast knowledge. The meetings did go well, however, and this site was recorded in the journals of both Lewis and Clark as "Council Bluff".
