Description: From Waythomas and others (1998): "Radiocarbon dates on peat and soil organic matter from bank exposures in the Akutan Harbor area indicate that volcanic ash began accumulating on Akutan Island about 9500 years ago. Some of the volcanic ash layers found in this area are distinctly light colored and these ash layers could be from distant volcanoes, probably west of Akutan Island (fig. 1 [in original text])."
