MacKerricher State Park in California has a unique beach  of ‘sea’ glass. It is the result of garbage dumped on the coastline in the early 20th century. In 1967 most of the garbage was cleared leaving only shards of glass. In the contest of water versus any other material, water always wins, and the edges of these glass shards were buffed smooth. Glass Beach as it is known became the property of California National Parks in 2002.

“In the confrontation between the stream and the rock, the stream always wins … not through strength but through persistence.”
