That designation did not last very long, however. In August, 1849, a column of U. S. Army “Mounted Rifles” marched by, headed for Oregon. They took a route somewhat closer to the canyon and could actually hear the thunder of the falls. A local Indian had told their guide about the feature, so the guide led Lieutenant Andrew Lindsay and George Gibbs, a civilian writer and artist, to see them. Gibbs drew the first known image of the falls, and the pair selected “Shoshone Falls” as a more appropriate name.
