Glass Beach, California
In 1949 this beach was an unrestricted dump. For 18 years glass, car parts, razors and other broken and used items were thrown away here before the council realised it was probably a bad idea. For the next 30 years, the elements worked their magic on all of the rubbish and with humans rectifying their mistake by removing rusted metals and other objects, this beach is now a unique and beautiful tourist attraction.
Just done fuck loads of research on this and then I find it on my dashboard
