Beyond the perimeter wall to the north courses the Pueblo Colorado Wash, the northern boundary of the Hubbell settlement. In some sections of the Ganado-Cornfields valley, the wash is spring-fed and runs year round. Melting snows in spring and heavy summer rains sometimes cause it to flood. In the Southwest a good source of water has always attracted people. The Anasazi (pronounced Ah-na-eeh-son-ni) (Navajo for "the ancient ones") lived in small villages up and down the valley hundreds of years ago. The Navajos came later, and then the traders - all attracted to the source of water.
