Paleoenvironments and Archaeology of the Trigo Mountains : Data Recovery in the Hart Mine and Cibola Quarry Areas, Yuma County, Arizona

The Trigo Mountains, located in the harsh, rugged desert north of Yuma, have been inhabited since some 10,000 years ago. This volume describes archaeological excavations by Statistical Research at 6 sites in the area. Research examined changes in the environment during the last 11,000 years, experimented with sourcing chipped stone tools through x-ray fluorescence, & explained why cached ceramic vessels were left by the prehistoric Yuman Indians.Shelley, Steven D. is the author of 'Paleoenvironments and Archaeology of the Trigo Mountains : Data Recovery in the Hart Mine and Cibola Quarry Areas, Yuma County, Arizona', published 1989 under ISBN 9780318681306 and ISBN 0318681307.
