When Mount St. Helens erupted on May 18th, 1980, 57 people were killed. What were they still doing in harm's way on the mountain, after months of warnings by scientists and rumblings from the volcano? Steve Olson has gone back to tell their stories in his new book, "Eruption: The Untold Story of Mount St. Helens." We spoke at Town Hall, in Seattle.
If you haven't been to the mountain in a while, it is well worth a visit. The recovery of nature is an incredible sight.
