Using tree rings to pinpoint ancient natural disasters

Evidence found in tree rings has uncovered massive mudflows that shaped the Pacific Northwest 500 years ago. University of Arizona researcher Bryan Black discusses how seismic activity that rocked Mount Rainier in the 16th century turned the landscape into what we see today.

Bryan Black spoke with Tim Swindle, professor emeritus of Planetary Science at the University of Arizona.
