Horses in a corral at the Hubbell Trading Post, a National Historic Site administered by the U.S. National Park Service near Ganado, a settlement on Navajo Nation land in far-northeast Arizona. Long a trading interface between Navajos and white settlers, the post was purchased by John Lorenzo Hubbell in 1878 — ten years after Navajos were allowed to return to the Ganado region from their U.S.-imposed exile in Bosque Redondo, near Fort Sumner, New Mexico. This ended what is known in Navajo history as the "Long Walk of the Navajo." Photo by Carol Highsmith, 2018.
