The Dine' (or Navajo) People are a unique group of American Indians still living the traditional way of life throughout the four corners region of the Southwestern United States. The Navajo people have returned to the original name, the Dine' (pronounced di-nay'h), given to them by their holy people. The Dine' land (aka Navajo reservation) on top of Oak Creek Canyon is the largest reservation established for the Dine', covering about 25,000 sq. miles of land, and is located in parts of Arizona, Utah, New Mexico, and Colorado. The Navajo were the first of the southwestern Indians to produce metal jewelry. Around the mid-19th Century a Navajo Medicine Man, Atsidi Sani, convinced a Mexican blacksmith to teach him the art of working with metal. When the Navajo returned to their homeland in 1868 after their imprisonment at Fort Sumner, New Mexico, traders arrived in the area bringing silver coins with them. It was with these coins that the Navajo began to make silver jewelry.
