Glass Beach, California, USA

Glass Beach is a beach in MacKerricher State Park near Fort Bragg. Sea glass goes back in history for as long as man has had glass. As the raw glass is broken into smaller pieces and slowly polished by the sand as it is rolled around in the surf, it becomes "beach", or "sea" glass: sea glass of gemstone quality. The beach is now frequently visited by tens of thousands of tourists yearly. Collecting is discouraged on the section of “Glass Beach” within and adjacent to the state park at “Site 3″, although most of the sea glass is now found on the other two glass beaches outside the state park area.
