The San Francisco Volcanic Field, of which Roden Crater is a part, sprawls over some 2300 square miles of Arizona near the southern margin of the Colorado Plateau. It is here that James Turrell has been working on a new kind of observatory. Visitors to the Roden Crater will be led to see the universe, sunset, full moon, clouds, the midday sky, light itself — in an intensified, altered way. A variety of spaces carved out of the crater will gather starlight and catch the moonlight. Grounded in psychology, physics and math, Turrell works in the medium of light upon a canvas of earth and sky and human perception.

At SITE Santa Fe, James Turrell will present huge maquettes of the individual projects with the Roden Crater, including models of the modifications he designed to the crater in order to produce a specific visual effect. He will also be showing photographs and topographic maps of the work-to-date.
