Las Misiones Antiguas is a photographic journey and written record of every peninsular mission and several visitas of Baja California. Each site was photographed and it's position recorded using a G. P. S. instrument. The description of each mission includes oral history from area residents. Sketches record the configuration of sites not previously mapped, and in the case of the largest Baja California mission, Comondú, the foundation was traced and old photographs were utilized to generate a computer model. This information was combined with historic photographs of many of the sites. More than 300 graphic images and a description of the history and major events at the sites make this book the most comprehensive source of information on these fascinating and rapidly deteriorating architectural treasures.
