Maverick's is a world-famous surfing location in Northern California (Moon Bay area). In the 2009-2010 contest held on Feb/13/2010 waves toped out at over 45 feet (13m). The break is caused by an unusually-shaped underwater rock formation. Mavericks is a winter destination for some of the world's best big wave surfers. Very few riders become big wave surfers; and of those, only a select few are willing to risk the hazardous conditions at Maverick's. This is an invitation-only contest that takes place every winter, depending on wave conditions.
