Artist Andres Amador is all about the temporary. Despite dedicating himself to large-scale, time-intensive sand sculptures and artwork, he's perfectly okay with the work being washed away moments later. He considers himself an Earthscape artist.
This powerful sand sculpture entitled Liberty Crumbling is the work of Damon Langlois, and shows Lincoln in his monument, but his head is depressingly in his hands. Below, the base of the sculpture shows deep cracks, like it's beginning to crumble.
