One of these chronologies has been calendar dated to AD 224–999 (775yr) crossdating with a living ring-width chronology from Prince William Sound, Alaska. Trees in this chronology were likely killed through inundation by sediments and meltwater from the advancing Geikie Glacier and its tributaries ca. AD 850. The earlier tree-ring chronology spans 545yr and is a floating ring-width series tied to radiocarbon ages of about 3000calyr BP. This tree-ring work indicates two intervals of glacial expansion by the Geikie Glacier system toward the...
