Roden Crater

Roden Crater is a earth 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 Roden Crater rather than just read about it. In short: Roden Crater is a cinder cone type of volcanic cone from an extinct volcano, with a remaining interior volcanic crater. It is located approximately 50 miles northeast of the city of Flagstaff in northern Arizona, United States.

Key takeaways

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

Reference excerpt

Roden Crater is a cinder cone type of volcanic cone from an extinct volcano, with a remaining interior volcanic crater. It is located approximately 50 miles northeast of the city of Flagstaff in northern Arizona, United States.

Art project For the past several decades, Roden Crater has been the site of a large-scale land art project by artist James Turrell. Turrell acquired the 400,000-year-old, 3-mile-wide (4.8 km) crater's land in 1977 with the aim of transforming the inner cone of the crater into a massive naked-eye observatory, designed specifically for viewing and experiencing sky-light, solar, and celestial phenomena. The fleeting winter and summer solstice events will be highlighted. Roden Crater demonstrates Turrell’s long interest in light, sky, and human perception. He drew on his aviation experience, studies in visual psychology, and research on ancient observatories to shape the project. The tunnels and chambers guide natural light and frame certain sky events such as rain, sunny, and stormy conditions, which emphasizes changes in color, depth, and visual response. Museums describe Roden Crater as a large, controlled environment for observing light and space. Adcock also notes that the site works like a simple observatory that helps people focus on how their eyes react to natural light. The first phase of construction included the excavation of over 1.3 million cubic yards (993,921 cubic meters) of earth to shape the Crater Bowl and the construction of the 854 ft (260 m) Alpha (East) Tunnel. When complete, the project will contain 24 viewing spaces and six tunnels. Kanye West filmed his 2019 movie Jesus Is King at Roden Crater. In 2019, Arizona State University partnered with James Turrell to collaborate on the project with the help of a $1.8 million gift. The project, referred to as the "ASU-Roden Crater Project" at ASU, is currently centered at the Herberger Institute for Design and the Arts, and hopes to foster interdisciplinary collaboration between the arts and sciences. Courses at ASU, including one titled "Indigenous Stories and Sky Science" taught by Professor Dalla Costa have already begun including the Roden Crater into their curriculum.

Future The Dia Art Foundation is continuing to advocate for the development of James Turrell's Roden Crater project in the Painted Desert in Arizona which was begun in the 1970s with Dia's support. James Turrell, who purchased the Roden Crater in 1979, had plans to open the crater for public viewing in 2011, then later tentatively set the opening for 2024. As of August 2025, the New York Times reported that Roden Crater was still unfinished.

2015 fundraising tours A one-time fundraising event held from May 14 to 17, 2015, allowed visitors to tour Roden Crater for a cost of $6,500 to Turrell's nonprofit organization.

Worked examples

Example 1 — a first encounter with Roden Crater

Start with the simplest possible case. Write down what Roden Crater claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth 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 Roden Crater 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 Roden Crater 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 Roden Crater

In research: Roden Crater appears in earth 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 Roden Crater 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: Roden Crater is common in secondary-school and first-year university syllabi. It links to neighbouring topics American contemporary art, Cinder cones of the United States, Extinct volcanoes of the United States, so understanding it makes those chapters shorter.
In everyday life: Look for Roden Crater 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.
