January 23, 2006—Northern California's Redwood National Forest is no place to make a leisurely climb.

Redwoods are the tallest trees on the planet, often reaching heights of 300 feet (91 meters).

Take an arduous trek to the top of this titanic redwood, and learn why scientists think the giant still has some growing left to do.
