Abstract: | Using 1929 aerial photos of western Santa Cruz Island, we identified numerous potential shell midden locations, followed by confirmation of site locations via field reconnaissance. Heavy grazing by sheep, cattle, and pigs closely cropped island vegetation in the early twentieth century, exposing shell middens now often covered with thick vegetation. We discuss the potential and limitations of early aerial photos as aids to archaeological site identification and management in island and coastal settings. Although results varied from island to island, we found historic aerial photos to be extremely useful for documenting previously unrecorded sites on Santa Cruz Island, ranging from historical EuroAmerican sites to Island Chumash sites dating to as much as 7250 cal BP. These methods may also be applicable to other islands around the world subject to heavy livestock grazing in the past, especially where introduced animals have been removed and recovering vegetation now obscures archaeological sites. |
