The artist who's happy with all his work being washed away

The California tide soon washes away work by Andres Amador - but for the artist, that is part of the point

With a bundle of three-pronged tools and hand-assembled rakes cast over one shoulder, the artist Andres Amador quietly descends the steep, crumbling dunes arching over a San Francisco shoreline to the beach below.

Scanning the horizon, stopping every so often to smile and pick up smooth stones, he walks until it seems right - until he finds a wide enough stretch of wet sand to serve as his canvas. Soon, it will come to life, etched with the large-scale angles and arches that form his captivating, signature style of Earthscape art.
