Abstract
The late Holocene eruption of Mount Churchill is the largest eruption in southeastern Alaska in the Holocene and one of the ten largest global eruptions during this time. The eruption blanketed southern Yukon and western Northwest Territories with 30-50 km3 of tephra. Excavation of trees killed by the eruption, tree-ring crossdating, and radiocarbon ages provides a new estimated age range for the eruption of AD 750 to 809 (95% confidence) using Bayesian statistics. Historical records from the chronicles of Theophanes and French annalists, along with Greenland ice cores, suggest that the eruption occurred in 797. The historical records further suggest that the eruption may have occurred in July of that year.
