Using the land as his medium, Robert Smithson was one of the most prominent earthworks artist, who employed elements of nature in situ or rearranged landscapes to create works that were subject to environmental natural changes. Most well-known for his Spiral Jetty , a site specific installation of rocks arranged in a spiral constructed on Utah's Salt Lake, Smithson unified this methodology with Jewish subject matter to create this graphic. Smithson photographed an interesting tract of land on the site of Mt. Moriah, traditionally considered the site where God created humans.
