Andy Goldsworthy (British, b. 1956) is a sculptor and photographer known for his land-art.  Working with natural materials, he documents the ephemerality of his installations through photography, often leaving the photographs as the only evidence that remains of a laborious process. His work is in the collections of the National Gallery of Art, Washington, D.C; Tate Britain, London; San Francisco Museum of Modern Art; Metropolitan Museum of Art, NY; and many more.
