Robert Smithson, Spiral Jetty
Great Salt Lake, Utah
Robert Smithson's monumental earthwork Spiral Jetty (1970) is located on the Great Salt Lake in Utah. Using black basalt rocks and earth from the site, the artist created a coil 1,500 feet long and 15 feet wide that stretches out counter-clockwise into the translucent red water. Spiral Jetty was acquired by Dia Art Foundation as a gift from the Estate of the artist in 1999.
