Mavericks is a surfing location in northern California outside Pillar Point Harbor, just north of the town of Half Moon Bay at the village of Princeton-by-the-Sea. After a strong winter storm in the northern Pacific Ocean, waves can routinely crest at over 25 feet (8 m) and top out at over 60 feet (18 m). Routinely, waves that break can be recorded on seismometers. 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. An invitation-only contest is held there most winters, when the waves are sufficient.(Wikipedia)
