In 1973, the year of Smithson’s death, Nancy Holt (Smithson’s widow) finished “The Sun Tunnels” located in Lucien, Utah. Holt was fascinated with light and the effects that the changing light would have in these tunnels. She placed four concrete cylinders in a formation whereby one cylinder‘s interior would be lit during the summer solstice and the opposite cylinder would be lit during the winter solstice. Each of the four would be pierced with the patterns of four constellations. By using infrared film, I was able to record the various shapes that these tunnels formed with the changes in light.
