Despite their attractiveness to early human migrants and maritime foragers, small islands often are overlooked in archaeological and historical ecological investigations compared to their mainland coastal and large island counterparts. Along Alta and Baja California, the Channel Islands and Isla Cedros have been the focus of extensive and intensive archaeological investigations. Despite the wealth of data from islands to the north and south, the Coronados Islands, a small set of four islands with a maximum length of two km positioned approximately 13 km off the northwestern Baja California coast, have been the subject of very little scientific archaeological research. As part of a collaborative bi- national research project between the Institute of Anthropology and History of Mexico and San Diego State University, the first season of fieldwork on the Coronados Islands was completed in October of 2016. Research efforts included the first systematic pedestrian survey of North Coronado Island and South Coronado Island, including the collection of diagnostic materials, ecofacts, and shell fragments for radiocarbon dating. These efforts have resulted in the identification, documentation, registration, and protection of 30 archaeological sites, including 27 prehistoric sites and three historical sites. My thesis research produced the first radiometric dates from the Coronados Islands, built an initial settlement chronology and occupational history, identified several prehistoric sites with high research potential, and laid the foundation for future archaeological and historical ecological studies of the island group.
