Fernald Point Prehistoric Site in Acadia National Park on Mount Desert Island preserves a shell midden and other remains that record a long span of prehistoric life on the Maine coast. Excavated mainly in 1977 by Dr. David Sanger as erosion threatened the shoreline, the site yielded evidence of human occupation dating to at least 1000 BCE, with some radiocarbon dates reaching 2000 BCE, and its heaviest use from 1 CE to 1300 CE. Finds included abundant shellfish remains, evidence of varied diet, changing pottery styles, parts of at least two house sites, and eight burials, including four graves placed within the midden.
