The Vanishing Race, Edward S. Curtis, 1904

Native Americans were the great casualty of the U.S.’s grand westward advance. Fearing the imminent disappearance of America’s first inhabitants, Edward S. Curtis sought to document the assorted tribes, to show them as a noble people—“the old time Indian, his dress, his ceremonies, his life and manners.” Over more than two decades, Curtis turned these pictures and observations into The North American Indian, a 20-­volume chronicle of 80 tribes. No single image embodied the project better than The Vanishing Race, his picture of Navajo riding off into the dusty distance.
