Rock Art Research

This paper reports the results of a program carried out twenty years ago to explore the ages of rock art in the sierras of Baja California. The relatively unknown rock art of the Sierra de Guadalupe represented the main focus of an investigation aiming to discover new painting sites, to collect paint samples and date selected paintings using radiocarbon. Collecting paint samples from the Gran Murals was done in all the sierras to gain a regional perspective into the time range and geographical distribution of this rock art tradition and link it with archaeological evidence obtained from excavations. The results from the field campaigns indicate considerable age for some of the Gran Murals and their repainting and provide a stimulus for additional research.
