What this episode covers

A University of Arizona-led team is using tree ring analysis to settle a long-standing debate about the eruption of the volcano Thera in Greece. Tree Ring researcher Charlotte Pearson says radiocarbon measurements from trees that lived at the time of the eruption trace the event to somewhere between 1600 and 1525 BC. Archeologists using pottery and other artifacts had placed the event at between 1570 and 1500 BC.
