Spiral Jetty is a famous earthwork sculpture situated on the northeastern section of the Great Salt Lake at Rozel Point peninsula in the state of Utah. The structure, which comprises black basalt rocks, mud and crystallized salt, coils from the shore into the lake in an anti-clockwise fashion, measuring 1,500 feet in length and 15 feet in width. Its construction is credited to American sculptor Robert Smithson. The visibility of the structure varies from season to season as determined by the levels of the lake.


Spiral Jetty represents one of the most impressive structures to have resulted from a shift in focus of some American artists to landscape-inspired works in the 1960s. Its construction started in April 1970 and took just six says to complete. The choice of location for the earthwork was said to have been informed by Smithson’s attraction to the red color of the lake, which is attributed to the presence in it of salt-tolerant algae and bacteria. The sculptor, who already had established a reputation for his widely varied works before the erection of the Spiral Jetty, brought on Bob Phillips of Parson’s Construction from Ogden, Utah to assist in the construction. A tractor, front-end loader and two dump trucks were needed to move the over 6,600 tons of black basalt rocks and earth required for the structure.

Spiral Jetty’s Visibility

Due to its location in the Great Salt Lake, Spiral Jetty has not always remained in view above water level. About two years after its completion, the earthwork sculpture became submerged under the water and remained so for 30 years before reappearing in 2002 as a result of drought. The elevation of the Great Salt Lake’s northeastern shore was about 4,195 feet when the artwork was built. So water levels above 4,195 feet can leave Spiral Jetty submerged. But you may still be able to see the tops of some of the rocks at 4,197 feet. It is advised to check the USGS website for water levels before visiting. The lake is usually at its lowest levels in the months of October and November.

Preservation of the Earthwork

Efforts have been made to preserve Spiral Jetty, which was donated by the Estate of Robert Smithson to Dia Art Foundation in 1999. It has been proposed that more basalt rocks be added to the site to address the challenges of rock discoloration and impact of increasing number of visitors as well as to ensure the structure is not easily submerged when water levels rise. Plans for exploratory oil drilling in the proximity of Spiral Jetty in 2008 were vehemently opposed by artists.
