On the delta at the mouth of Unkar Creek, the School of American Research undertook the first excavations ever carried out in the Grand Canyon.With 52 recorded sites, Unkar delta holds one of the largest concentrations of ruins in the canyon, representing four different periods of occupation between A.D. 900 and 1150. This volume offers thorough descriptions of the material culture of the Unkar inhabitants and reconstructs their settlement history and way of life.
