Rocas Alijos

This is the first comprehensive description of the site, which is the top of a remnant oceanic volcano 180 nautical miles off Baja California. The book presents extensive details on the observations made during two major expeditions in 1990 and 1993, including the history, rocks, water, soil, and biota. The site is highly significant for biogeographical studies, lying at the boundary between major provinces. It also provides ready access to dating the vulcanism of the region. As a case study, this volume is extremely rich in detail, integrating the various observations into a single picture of the site. The book will be indispensable to researchers concerned with the Eastern Pacific, and to persons involved in the planning of expeditions, resource management, or long-term trends in environmental conditions.
