The 1964 Alaskan earthquake shifted the land mass significantly, pushing many archaeological sites, e.g., prehistoric and historic Indian, Russian American, World War II, maritime, and mining sites, to and beyond the coastline. The Exxon oil spill has posed a hazard to these cultural resources: obscuring the visibility of shorefront sites, causing erosion, contaminating material for potential radiocarbon dating of samples, and affecting archaeologiocal stratigraphy and organic material. Cleaning activities may also inadvertently damage these resources. Exxon has complied with Section 106 in providing archaeologists to review cultural resource information, to participate in precleaning activities, to advise on cleaning procedures, and to participate in postcleaning evaluations.
