Modeling and Monitoring Submerged Prehistoric Sites during Offshore Sand Dredging and Implications for the Study of Early Holocene Coastal Occupation of Southern California

John Hildebrand & Andrew York
Beach sand dredging projects off the coast of San Diego County in Southern California provide data for improved understanding of the strategraphic setting for early Holocene sediments and the potential for offshore presence of buried archaeological materials. Geophysical data, core sediments, and analysis of recovered fossils allowed models to be developed for six offshore borrow sites within drown river valleys. These site-specific models were tested during dredging operations, and the dredge spoil was monitored for...
