Work continues on the use of marine food resources in the Puerto Peñasco area. Extensive shell middens reveal thousands of years of both shellfish harvesting and fishing in the north east corner of the Gulf of California. This work has been lead by Mike Foster (Western Cultural Resource Management) and Douglas Mitchell (PaleoWest Archaeology), with the assistance of David Dettman, Gary Hucklebury, and Karin Adams.
