== Accomplishments ==
The Corps met their objective of reaching the Pacific, mapping and establishing their presence for a legal claim to the land. They established diplomatic relations and trade with at least two dozen indigenous nations. They did not find a continuous waterway to the Pacific Ocean<ref>[[#Fritz|Fritz, 2004]] pp. 33–35</ref> but located a Native American trail that led from the upper end of the Missouri River to the Columbia River which ran to the Pacific Ocean.<ref>[[#Ambrose|Ambrose, 1996]] pp. 352, 407</ref> They gained information about the natural habitat, flora and fauna, bringing back various plant, seed and mineral specimens. They mapped the topography of the land, designating the location of mountain ranges, rivers and the many Native American tribes during the course of their journey. They also learned and recorded much about the language and customs of the Native American tribes they encountered, and brought back many of their artifacts, including bows, clothing and ceremonial robes.<ref>[[#Ambrose|Ambrose, 1996]] p. 204</ref>
