When an ominous mushroom cloud of ash erupted from Mount Redoubt 31 years ago today, it was anyone’s guess how long the volcanic event would last.

“The rule of thumb for looking at volcanoes like Redoubt is you typically look at how it’s erupted in the past and that often gives you good guidelines in the future," said John Power, a research geophysicist at the Alaska Volcano Observatory.

On June 6, 1912, a newly formed vent unleashed the largest volcanic eruption of the 20th century in what became known as the Valley of 10,000 Smokes in Katmai National Park and Preserve. Today, it's a fascinating backpacking destination for anyone with an interest in geology or just an appreciation for impressive scenery.
Host Jenny Neyman speaks with Cathy Bell, chief of interpretation and education at Katmai National Park and Preserve, about the geology of the valley and how to plan a visit.
