Its placid and deep-blue water belie Crater Lake’s violent past.
On Tuesday evening, geologist Dave Ramsey will reveal how the caldera at the center of Oregon’s famed national park stood as towering Mount Mazama until a massive eruption 7,700 years ago.

Ramsey, a geologist with the U.S. Geological Survey in Vancouver, will describe how scientists have used high-precision echo sounding as well as a submarine to probe underwater volcanoes, lava deltas and giant landslides in Crater Lake.
Volcano Views and Brews is held on the third Tuesday of each month.
