William Clark's signature at Pompeys Pillar

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.
