Book Description
Crisscrossing Pleistocene terrace tops and overlooking the Gila River in southeastern Arizona are acres and acres of rock alignments that have perplexed archaeologists for a century. Well known but poorly understood, these features have long been considered agricultural, but exactly what was cultivated, how, and why remained a mystery. Now we know. Drawing on the talents of a team of scholars representing various disciplines, including geology, soil science, remote sensing, geographical information sciences (GISc), hydrology, botany, palynology, and archaeology, the editors of this volume explain when and why the grids were built. Between A.D. 750 and 1385, people gathered rocks from the tops of the terraces and rearranged them in grids of varying size and shape, averaging about 4 meters to 5 meters square. The grids captured rainfall and water accumulated under the rocks forming the grids. Agave was planted among the rocks, providing a dietary supplement to the maize and beans that were irrigated on the nearby bottom land, a survival crop when the staple crops failed, and possibly a trade commodity when yields were high. Stunning photographs by Adriel Heisey convey the vastness of the grids across the landscape.

Book Description
This is not only a story about mining, nor is it an autobiography, but rather a collection of interesting and sometimes strange stories from the author's life, tracing his way from an adventurous childhood through his training as a mining engineer, his service as a bomb disposal officer in the U.S. Army, and his adventures dealing with different cultures in places that most Americans only go as tourists -- if at all. What is it like to descend 11,000 feet below surface in a South African gold mine? To disarm a misfired missile in the launch silo? To survive an apocalyptical cargo cult event in Papua New Guinea? To face the blazing stars at night on the altiplano in Bolivia? To travel up the Amazon on a fool's errand, dining on armadillo on the half shell? To search for the Queen of Sheba's mines in Yemen? To expose mining scams in Arizona? These are some of the stories that the author relates in his own unique, informative, and sometimes ribald way. Any fan of travel and adventure stories should enjoy this book.

Book Description
The Safford and Aravaipa valleys of Arizona have always lingered in the wings of Southwestern archaeology, away from the spotlight held by the more thoroughly studied Tucson and Phoenix Basins, the Mogollon Rim area, and the Colorado Plateau. Yet these two valleys hold intriguing clues to understanding the social processes, particularly migration and the interaction it engenders, that led to the coalescence of ancient populations throughout the Greater Southwest in the fourteenth and fifteenth centuries A.D. Because the Safford and Aravaipa valleys show cultural influences from diverse areas of the pre-Hispanic Southwest, particularly the Phoenix Basin, the Mogollon Rim, and the Kayenta and Tusayan region, they serve as a microcosm of many of the social changes that occurred in other areas of the Southwest during this time. This research explores the social changes that took place in the Safford and Aravaipa valleys during the thirteenth through the fifteenth centuries A.D. as a result of an influx of migrants from the Kayenta and Tusayan regions of northeastern Arizona. Focusing on domestic architecture and ceramics, the author evaluates how migration affects the expression of identity of both migrant and indigenous populations in the Safford and Aravaipa valleys and provides a model for research in other areas where migration played an important role. Archaeologists interested in the Greater Southwest will find a wealth of information on these little-known valleys that provides contextualization for this important and intriguing time period, and those interested in migration in the ancient past will find a useful case study that goes beyond identifying incidents of migration to understanding its long-lasting implications for both migrants and the local people they impacted.
