The year 1968 marks the 100th anniversary of the signing of the Treaty of Peace between the Navajo tribe and the U.S. Government. The treaty, signed by 29 Navajo headmen and 10 officers of the U.S. Army on June 1, 1968, brought to an end a tragic period of suffering, hardship, deprivation, and exile at the Bosque Redondo, New Mexico. During the intervening century, the Navajo people have witnessed a substantial population increase and have undergone drastic and far-reaching changes in their economy, self-government, social status, education, and living conditions. The photographs, with accompanying text, capture a century of progress (1868-1968) for the Navajo Tribe. The contents include Dinneh: The People; A Time for Suffering; The Treaty; Exodus; A New Beginning; and A Time for Living. (FF)
