Environmental artist Martin Hill started creating interesting sculptures in nature in the early 1990s. His purpose is to make ”environmental sculptures in nature that return to nature”. In the end, his photographs of the sculptures are all that remains. He is based in New Zealand and so far he has made various kinds of patterns, circles and ”guardians” out of all sorts of materials. He usually uses snow, ice, branches, trees, sand, feathers, berries, pebbles etc. Martin Hill works with Philippa Jones on these projects and this is their way of connecting with nature and attempting to send out a message about the importance of preserving it.
