Mt. St. Helens Back from the Dead (Episode #3710H)
KQED World: Fri, Mar 7, 2014 -- 5:00 AM
When Mount St. Helens erupted in 1980, every living thing in the blast zone was buried beneath 300 feet of avalanche debris, covered with steaming mud and, finally, topped with a superheated layer of frothy rock from deep within the earth. It seemed as though Mount St. Helens might remain a wasteland forever. When biologist Charlie Crisafulli first flew over the disaster zone, finding no sign of life, little did he realize that his own life would be forever changed. Crisafulli has remained at the site for 27 years, documenting the dramatic return of plant and animal life to the barren landscape and pioneering a new understanding of the interaction between geologic forces and the life surrounding the mountain. Nova brings viewers on a journey of a landscape brought back from the dead.

Ground Zero Supertower (Episode #4016H)
KQED Life: Sat, Mar 1, 2014 -- 2:00 AM
Nova returns to Ground Zero to witness the final chapter in an epic story of engineering, innovation, and the perseverance of the human spirit: the completion of One World Trade Center, the skyscraper rising up 104 stories and 1,776 feet from the site where the Twin Towers once stood. In this update of Nova's "Engineering Ground Zero, " which featured behind-the-scenes access to the struggles of the engineers and architects working at 1 WTC and the National September 11 Memorial and Museum, Nova goes inside the construction of the new tower's final floors and the installation of its soaring, 800-ton spire and beacon. But 1 WTC isn't the only engineering marvel taking shape here: Nova goes underground to see the construction of a multi-billion dollar transit center whose sweeping, sinuous design is said to be inspired by the shape of a bird being released from a child's hand. Will the buildings be completed on time under competing business, environmental, and safety demands? And will the final product be a fitting site for national remembrance?
