Link to Explorer: Climbing redwood giants documentary
Documentary Description
They are living giants; one of the Earth's largest and oldest trees.
Some tower more than 350 feet high, taller than the Statue of Liberty;
some may have been seedlings when Jesus was born. Yet these natural
legends still shroud centuries-old secrets. In a major National
Geographic cross-platform event, which includes the October 2009 cover
story for the magazine, we'll reveal the little-explored environment of
the redwoods using high-tech aerial laser surveys and breathtaking
imagery.
