Volcanic Rumblings In The Cascades?

A bulge grows beneath the recreational playground of the Central Oregon Cascades in the early 2000s. In 2004, Mount St. Helens erupts—again. What’s going on? Scientists from the Cascade Volcano Observatory probe the unsolved mysteries of these ‘volcanoes in our backyard.' Originally broadcast in 2008.

OPB is revisiting decades of stories our reporters and producers captured while working with scientists, photographers, adventurers and explorers on the volcano since its eruption on May 18, 1980.
