Worldwide, coastal archaeological sites are being lost and/or damaged as sea-level rise and associated storm events impact the coast. In Maine, over 2,000 aboriginal shell middens, recording over 5,000 years of coastal occupation, dot the coast. Composed largely of clam and oyster shells, these deposits also contain bone, ceramic and lithic artifacts. Additionally, they contain an extensive faunal and floral record, including now extinct species, and represent a lengthy paleoenvironmental record. All of these sites are disappearing at varying rates, some catastrophically. Only 2-3 of Maine coast shell middens are professionally excavated each year, meaning that thousands of years of cultural and environmental history slips into the ocean, unrecorded each year.
