Environmental sculpture is a form of art that integrates with the natural landscape, often using materials found in the environment. These sculptures can be made from stone, wood, or metal and are designed to enhance or interact with their surroundings. Artists aim to create a dialogue between the artwork and nature, encouraging viewers to appreciate both. This type of sculpture can be temporary or permanent and is often site-specific, meaning it is created for a particular location. Notable examples include the works of artists like Robert Smithson, known for his piece Spiral Jetty, which is located in Utah's Great Salt Lake.
