Augustine Shuyak Island Ash 3
Start: 3620 yBP ± 25 Years [1]
Stop: 3360 yBP ± 25 Years [1]
Event Type: Explosive
Description: From Waitt and Beget (2009): "On Shuyak Island 110 km southeast of Augustine (fig. 1A [in original text])...a higher Augustine tephra there dates between 3,620 and 3,360 yr B.P. (table 2; plate 2, section RBW 93Ko.09 [in original text]) (tephras identified in Riehle and others, 1998)."
From Waitt and Beget (1996): "On Shuyak Island 100 km south-east of Augustine, distal fall tephra of Augustinian chemical provenance (probe analysis of glass) dates between about 3620 and 3360 y B.P. (table 2 [in original text]; Riehle and others, 1996)."
From Waythomas and Waitt (1998): "The oldest known distal volcanic ash from Augustine Volcano was deposited about 3600 yr B.P. on Shuyak Island, 100 kilometers southeast of Augustine Volcano (fig. 1 [in original text]; Waitt and others, 1996)."
