At that time the land was owned by the Union Lumber Company, and locals referred to it as “The Dumps”.
In 1967 the North Coast Water Quality Board closed the area completely and initiated a series of cleanups.
Over the next several decades the pounding waves cleansed the beach, wearing down the discarded glass into the small, smooth, colored trinkets that cover the beach today.
