Archaeology and History of the Western Midriff Islands in the Gulf of California

Hot, arid, and uninhabited, the western Midriff Islands lie in the Gulf of California, surrounded by an often-treacherous sea. Given these conditions, why would ancient people go there, and why would anybody go there today? Thomas Bowen addresses these questions in the first comprehensive history of these islands.

Bowen draws on a wide range of sources, including the first archaeological field work ever conducted on the islands, written accounts dating back to the sixteenth century, oral histories of native people, contemporary interviews, and his own firsthand experiences. Among those cast in the islands’ historical drama are the Seri (Comcaac) people of Sonora, the extinct Cochimís of Baja California, Spanish explorers, Jesuit missionaries, pearl fishers, egg collectors, guano miners, hydrographers, cartographers, small-scale Mexican fishermen, recreational anglers, writers, photographers, ecotourists, shipwreck victims, and, most importantly, scientists. The final chapter documents the impact of this human activity on the islands’ ecosystems and examines conservation efforts now underway. Compelling and richly illustrated, this broadly based work provides a unique picture of these extraordinary islands.

Praise and Reviews:

“Bowen’s excitement for good science and hard data, field adventure, and wide-ranging conservation brings it all together through his splendid storytelling and narrative, all backed by his careful field journals. And it is all quite infectious.”
—Daniel W. Anderson, professor emeritus, Department of Wildlife, Fish, and Conservation Biology, University of California, Davis 



“From the very first pages, Bowen vividly paints a picture of this remote region of extreme beauty and isolation. Without recourse to equations or highly abstracted models, he deftly situates both the writing and the research behind it within robust bodies of cultural, natural, and historical theory. This work is of high importance in terms of both sheer volume and range of information about an understudied, underreported, and underrecognized region of North America.”
—Matthew Des Lauriers, Department of Anthropology, California State University, San Bernardino
