Spiral Jetty

Spiral Jetty is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Spiral Jetty rather than just read about it. In short: 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.

Key takeaways

  • Spiral Jetty belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Spiral Jetty to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Spiral Jetty from memory before moving on to harder problems.

Reference excerpt

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 1,500-foot-long (460 m), 15-foot-wide (4.6 m) 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 1,500-foot-long (460 m), 15-foot-wide (4.6 m) 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. 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.

Worked examples

Example 1 — a first encounter with Spiral Jetty

Start with the simplest possible case. Write down what Spiral Jetty claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Spiral Jetty before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Spiral Jetty ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Spiral Jetty

In research
Spiral Jetty appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Spiral Jetty in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Spiral Jetty is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1970 establishments in Utah, 1970 sculptures, Great Salt Lake, so understanding it makes those chapters shorter.
In everyday life
Look for Spiral Jetty outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
