Robert Smithson's earthwork Spiral Jetty (1970) is located at Rozel Point peninsula on the northeastern shore of Great Salt Lake. Using over six thousand tons of black basalt rocks and earth from the site, Smithson formed a coil 1,500 feet long and 15 feet wide that winds counterclockwise off the shore into the water. In 1999, through the generosity of the artist Nancy Holt, Smithson’s wife, and the Estate of Robert Smithson, the artwork was donated to Dia Art Foundation.

Art: Spiral Jetty, 1970

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.

“I like landscapes that suggest prehistory,”Smithson once observed. The site of Spiral Jetty was chosen by the artist for the lake’s unusual ecological and geological properties. The reddish coloration of the water, caused by the high presence of microbes, initially attracted Smithson to the north arm of the lake. The spiral shape alludes to the molecular lattice of the salt-crystal deposits found throughout the lake’s expanse, and in forming the work, he chose to use basalt boulders of hardened lava found along the peninsula, scattered remnants of the now extinct volcanos in the area.

The fractured landscape, fluctuating water levels, and the water’s salinity also speak of the artist’s preoccupation with the concept of entropy. Smithson envisioned an artwork in a state of constant transformation whose form is never fixed and undergoes decay from the moment of its creation. His thinking was equally shaped by his understanding of the third law of thermodynamics as well as a fascination in science fiction and popular science. 

As a path for walking and looking, Spiral Jetty is a sculpture to be experienced. The act of traversing the earthwork is a prominent image in the eponymous film completed months after Smithson built the sculpture. Along with aerial shots of Spiral Jetty is a sequence of images of the artist running on the sculpture. Reaching the innermost point, Smithson gazes out at the spiral path, lake, and mountains. Spiral Jetty serves as a site from which to view the surroundings—the prehistoric environment that Smithson selected for it.

Visitor Information

Dia Art Foundation is proud to be the owner and steward of Robert Smithson’s Spiral Jetty. We make every effort to uphold the artist’s intentions and to protect the artwork for all of us now and for future generations.

Please leave Spiral Jetty and the natural environment exactly as you found it. Visitors are required to “leave no trace” at the site by carrying out any waste with them. Do not take or paint rocks, make fire pits, or stamp on vegetation.

There are no bathrooms, food, fresh water, nor fuel at the site. Guests are advised to bring boots, food, and water along with weather-appropriate clothing. Drinking water and bathrooms can be found en route to Spiral Jetty at the Golden Spike National Historic Site Visitor Center.

Due to a local drought, Spiral Jetty is currently completely visible. For current lake levels in the northern half of Great Salt Lake, see data provided by the United States Geological Survey for Great Salt Lake water levels.
