The Lewis and Clark Expedition is more than the story of two men. It is the story of many: individuals and groups, military men and scientists, a president and a slave, women and men, French-speaking boatmen and American Indians. It is a story of loss and hope. It is a story of changes that began in 1803 and that continue today. Learn more about some of these stories by visiting People and Places.

Two hundred years after the Lewis and Clark Expedition, the only physical evidence of the journey is found near Billings, MT. In July 1805, William Clark carved his name into the soft rock of what he called Pompeys Tower. This site is now preserved at Pompeys Pillar National Monument.
