Spiral Jetty is a work of land art constructed in April 1970 that is considered to be the most important work by American sculptor Robert Smithson. Smithson documented the construction of the sculpture in a 32-minute color film also titled Spiral Jetty. Built on the northeastern shore of the Great Salt Lake near Rozel Point in Utah entirely of mud, salt crystals, and basalt rocks, Spiral Jetty forms a , counterclockwise coil jutting from the shore of the lake.

In 1999, the artwork was donated to the Dia Art Foundation; it is one of 12 locations and sites owned by the foundation. Since its initial construction, those interested in its fate have dealt with questions of proposed changes in land use in the area surrounding the sculpture. In order to preserve the work, Dia asks that visitors not take existing rocks from the artwork, make fire pits, or trample vegetation. There are no facilities at the site, so visitors must carry any waste away with them.

Description The sculpture is built of mud, precipitated salt crystals, and basalt rocks. It forms a , counterclockwise coil originally jutting from the shore of the lake, though due to the drying of the lake, as of 2022 a mile of lakebed separates Spiral Jetty from the shore. Depending upon the water level of the Great Salt Lake, the sculpture is sometimes visible and sometimes submerged.

Construction

Smithson reportedly chose the Rozel Point site based on the blood-red color of the water and its connection with the primordial sea. The red hue of the water is due to the presence of salt-tolerant bacteria and algae that thrive in the extreme 27 percent salinity of the lake's north arm, which was isolated from freshwater sources by the building of a causeway by the Southern Pacific Railroad in 1959.

Smithson was reportedly attracted to the Rozel Point site because of the stark anti-pastoral beauty and industrial remnants from nearby Golden Spike National Historic Site, as well as an old pier and a few unused oil rigs. While observing the construction of the piece from a helicopter, Smithson reportedly remarked "et in Utah ego" as a counterpoint to the pastoral Baroque painting et in Arcadia ego by Nicolas Poussin.

To move the rock into the lake, Smithson hired Bob Phillips of nearby Ogden, Utah, who used two dump trucks, a large tractor, and a front end loader to haul the 6,650 tons of rock and earth into the lake. It is reported that Smithson had a difficult time convincing a contractor to accept the unusual proposal. Spiral Jetty was the first of his pieces to require the acquisition of land rights and earthmoving equipment. Phillips often told people that his best-known construction job was "the only thing I ever built that ... was to look at and had no purpose".

Phillips described the use of earth-moving equipment along the lakeside as "tricky", and said of Smithson that "I don't think he had done any geology work or anything on it. He just had in his mind what it should look like.... He just had the eye for it. I assume it was the artist in him." Work began on the jetty in April 1970. The work was constructed twice; the first time requiring six days. After contemplating the result for two days, Smithson called the crew back and had the shape altered to its present configuration, an effort requiring moving 7,000 tons of basalt rock during an additional three days.Sean P. Means, Contractor brought Spiral Jetty to life, Salt Lake Tribune, April 19, 2016, p. A11

Phillips' son appeared on the PBS Antiques Roadshow program in 2017 with a photograph and collection of documents related to the building of the project.

Ownership The sculpture was financed in part by a $9,000 USD grant from the Virginia Dwan Gallery of New York. In 1999, Spiral Jetty was donated to Dia. As owner and custodian of Spiral Jetty, the foundation maintains the lease from the Utah Division of Forestry, Fire & State Lands of state sovereign lands in Great Salt Lake upon which the artwork is sited.

Smithson died in a plane crash in Texas three years after finishing the Spiral Jetty.

Dia, along with the Holt/Smithson Foundation, claim ownership of copyright for Spiral Jetty. However, the work itself does not meet the legal standard for copyrightable material, which in the United States includes the stipulation that a work must be "fixed" in a "tangible medium." While Spiral Jetty was created in a tangible medium, its inherent physical composition — piles of dirt, rocks, and salt that are subject to the erosive forces of the Great Salt Lake — means it is not fixed: "This lack of fixed form problematizes the work’s intellectual property protection. The heart of the work — the idea that it presents made manifest through an ephemeral environmental intervention — cannot be protected based on the guidelines provided under the Copyright Act." Dia can and does claim copyright over images of Spiral Jetty created by the foundation. However, due to the physical work's lack of copyright protection, visitors do not need permission to create or publish their own photographs of the sculpture.

Preservation

Preservation efforts for Spiral Jetty face considerable challenges due to the remote location of the site and its vulnerability to natural environmental conditions. These challenges are exacerbated by the impacts of climate change and increased tourism activity.

At the time Dia acquired Spiral Jetty, the work was fully submerged in the lake. Beginning in the early 2000s, however, sustained drought in Utah caused water levels to recede, and Spiral Jetty became visible for the first prolonged period in its history. As a result, the prominence of Spiral Jetty has risen dramatically over the past decade, increasing both the visitorship to the site and the public's interest in the artwork, at the local, national, and international levels.

Dia is committed to maintaining a photographic record of the work and documenting changes to the piece over time. Dia collaborates with two organizations in Utah, the Great Salt Lake Institute at Westminster College (GSLI) and the Utah Museum of Fine Arts (UMFA) at the University of Utah, who have been deeply involved in the advocacy of Spiral Jetty over the years.

In 2008, plans were announced for exploratory oil drilling approximately five miles from the jetty.Kennedy, Randy. The New York Times. "Artists Rally for Spiral Jetty in Utah" February 6, 2008 This was met with strong resistance from artists, and the state of Utah received more than 3,000 emails about the plan, most of them opposing the drilling.Johnson, Kirk. The New York Times, March 27, 2008. "Plans to Mix Oil Drilling and Art Clash in Utah"

The year 2009 marked a collaboration between Dia and the Getty Conservation Institute, with the objective of creating a repeat photography system. This system was specifically designed to document the evolving changes taking place at the Spiral Jetty site and to closely monitor it for any conservation requirements.Rand Eppich et al. (2011). "Monitoring Spiral Jetty: Aerial Balloon Photography," ICOM International Council of Museums Committee for Conservation, pp. 1-8

Starting in late 2016, Dia initiated the practice of sharing aerial photographs of Spiral Jetty, captured twice a year since 2012. These photographs were taken from nearly identical vantage points as part of Dia's dedication to documenting the evolving changes of the artwork over time through photographic records.Dia Art Foundation (n.d.), "Spiral Jetty Aerial Documentation"

The issue of preservation has been complicated by ambiguous statements by Smithson, who expressed an admiration for entropy in that he intended his works to mimic earthly attributes in that they remain in a state of arrested disruption and not be kept from destruction.

Dia's website states that visitors are prohibited from removing rocks from the artwork or from stepping on vegetation that is on the grounds of the artwork. Visitors are also prohibited from constructing fire pits near the artwork or on the parking lot. If caught, visitors will face strict fines. The website also states that visitors are instructed to carry out their waste.

Film

In 1970 during the construction of the jetty, Robert Smithson wrote and directed a 32-minute color film, Spiral Jetty. The film was shot by Smithson and his wife Nancy Holt, and funded by Virginia Dwan and Douglas Christmas.

The film documented the construction process and also formed an ancillary artwork. Smithson combines his interest in geology, paleontology, astronomy, mythology and cinema, stating that he had an interest in documenting "the earth's history". In conjunction with filmed sequences of the jetty, Smithson incorporates footage of dinosaurs in a natural history museum and the ripped pages from a history text. During this scene, Smithson refers to the institutions of history: "the earth's history seems at times like a story recorded in a book, each page of which is torn into small pieces. Many of the pages and some of the pieces of each page are missing". Smithson's narrative supports an alternative view of historical discourse and the art object's placement or production outside of the museum institution. His writings also indicate that the helicopter film sequences over the jetty were a method of "recapitulating the scale of the jetty". By visually disorienting the viewer, Smithson is able to negate a time and place for the materiality of the artwork or create what he calls a "cosmic rupture".Smithson, Robert. The Spiral Jetty, 1970, published in Robert Smithson: The Collected Writings, edited by Nancy Holt, New York University Press, pp. 109-113 Through this state, the viewer is meant to be unable to categorize or classify the site, and will be left in a state free from the dialect of history.

The film has been described as Smithson's attempt to "leave the viewer with a sense that the monumental artwork is connected to a vast mental landscape of meanings and associations".Campagnolo. K. M. (2008). Spiral Jetty through the Camera's Eye. Archives of American Art Journal, 47(1/2), 16–23.

Legacy

The work was named Utah's official state work of land art in 2017. April 2020 marked the Spiral Jettys 50th anniversary, which Smithson referred to shortly before his death in 1973 as "the work of the decade". It was listed on the National Register of Historic Places in 2024.

Criticism The ephemeral nature of the Spiral Jetty (sometimes visible, sometimes submerged) sparked inquiriesOwens, C. (1980). The Allegorical Impulse: Toward a Theory of Postmodernism. October, 12, 67–86. into the enduring influence of the artwork and the importance of its various representations, such as photographs, films, and essays. The photographs played a critical role in preserving and promoting the earthwork's growing renown, acting as the primary connection between the object and its state of being forgotten. Smithson's conceptual framework, centered around the concepts of temporality and entropy, emphasized the dynamic and destructive elements at play, often referencing the gradual decline and disintegration of the artwork. Through his essays and interviews, the artist articulated his awareness of these forces at work within his artistic practice. Borrowing from the term entropy, Smithson indicated that the earthworks were "suggestions of sites external to the gallery situation".
