Spiral Jetty – April 2019 (photo by Shawn Grant)

Robert Smithson’s Spiral Jetty, located at Rozel Point on the northeastern shore of Great Salt Lake in Utah, is one of the most remarkable examples of Land art. In 1970, assisted by a crew operating dump trucks, a tractor, and a front loader, Smithson displaced some 6,000 tons of black basalt rock and earth from the adjacent shore to form a coil 1,500 feet long and approximately 15 feet wide, winding counterclockwise into the lake. Created at a time when water levels were particularly low, Spiral Jetty was submerged in 1972. Droughts caused the lake to recede in 2002, and the sculpture has remained visible ever since. https://www.diaart.org/visit/visit/robert-smithson-spiral-jetty
