A monster lurks just off the coast of Northern California. Known as "Mavericks," this surf break north of Half Moon Bay generates some of the biggest waves in the world, and draws the big wave surfers that live for them. But what makes these waves so big? QUEST talks with scientists who are getting to the bottom of it and the big wave surfers willing to take their lives in their hands for the ultimate thrill ride.
