Age, Extent and Climatic Significance of the c. 3400 BP Aniakchak Tephra, Western Alaska, USA
Tephra deposits at Whitefish Lake and Cape Espenberg on the northernmost Seward Peninsula of western Alaska were derived from the Aniakchak Caldera on the Alaska Peninsula more than 1500 km to the south. Radiocarbon dates on the climactic, caldera-forming Aniakchak eruption and on proximal and dista...
