In 1900, unscrupulous timber baron Jim Fallon plans to take advantage of a new law and make millions off California redwood. Much of the land he hopes to grab has been homesteaded by a Quaker colony, who try to persuade him to spare the giant sequoias...but these are the very trees he wants most. Expert at manipulating others, Fallon finds that other sharks are at his own heels, and forms an unlikely alliance.

Donald has a ride-on sized train layout in his backyard. There's a large tree (home to Chip 'n Dale) that's out of scale, so Donald moves it while they're out; they come back to see their tree moving. No problem; one of Donald's model houses is just their size.

Donald is a park ranger, assigned to protect the giant tree Old Sequoia from a pair of beavers that bear a striking resemblance in their tactics and speech to Chip 'n' Dale.

Feel the rush of the breathtakingly beautiful National Parks of California with one deep breath of the summer air.

The tree surgeon (a donkey) races to the giant sequoia, which isn't feeling well. His techniques, though, seem better suited to treating a person.

They are giants—stretching more than 300 feet above the ground, with hidden gardens and mysterious predators thriving within their canopy. National Geographic reveals the unexplored environment of the California redwoods in an epic, year-long exploration. Obsessive redwood climber Steve Sillett of Humboldt State University explores their massive crowns, discovering new record-breaking trees, while escaping falling branches and crashing trees in the process. Down below, National Geographic Explorer-in-Residence Mike Fay charts the redwood range to size up the past and future of these primeval trees threatened in 21st century California.
