A postglacial pollen record from western Kodiak Island, Alaska

Abstract

Excavation of organic deposits in a seasonally dry depression atop a moraine crest near the village of Karluk, on the west side of Kodiak Island, has provided a detailed paleoenvironmental record. Radiocarbon dating indicates that the base of the section is approximately 4260 14C yr in age. Seven minor volcanic ashes are recognized prior to the onset of seasonal drying of the basin at about 2330 BP. A major ash fall (2 cm) is recorded at about 1625 BP. -from Author
