PBS Nova - Mount St Helens - Back from the Dead (2010)

One of the most violent natural disasters of our time, the colossal eruption of Mt. St. Helens in 1980 blasted away an entire mountainside. Over 200 square miles of pristine forest were buried under millions of tons of lava, ash, mud, and avalanche debris. How could life ever return to this barren moonscape? A lone ecologist, Charlie Crisafulli, spent months in the blast zone and was astonished and puzzled by how quickly plants and animals colonized the wasteland. In this program, stunning cinematography and time-lapse photography trace the dramatic story of how Crisafulli witnessed life's return and figured out the puzzle. Now another question arises: How soon could another catastrophic eruption occur?
