The California coast is an edge. It's the place where 1,100 miles of shoreline meets the largest ocean on the planet. Many different forces collide there, and a lot of exciting things happen. The coast is a geological edge, zippered to North America by 800 miles of the San Andreas Fault and battered by the Pacific Ocean.
It's also a social, political, cultural, spiritual, economic and technological edge. It is where the most populous state and sixth-largest economy in the world is exposed to wind, waves, tides, El Niños, earthquakes and tsunamis. These forces made California's coastline rugged, beautiful and beckoning.
