Sun Tunnels: Shifting Shadows
Sun Tunnels: Shifting Shadows depicts the shifting patterns of light and shadow over the course of a long July summer day inside one tunnel of Nancy Holt’s landmark earthwork Sun Tunnels (1973-76), located in Utah’s Great Basin Desert. The sculpture comprises four concrete structures arranged in an X-formation, positioned to frame the sun as it rises and sets at the solstices. The composite of thirty photographs captures changing light conditions recorded by Holt at regular intervals over the course of a single day. She traces the movement of the sun through the shadow’s passage from one side of the tunnel to the other, eventually including her own shadow and marking her presence. This photographic artwork makes material Holt’s desire to bring the stars down to earth, with the perforations in the surface of the tunnels mapping out star constellations, bringing the sunlight to the ground in an echo of the celestial pattern above. Holt made this series of photographs in July 1976 shortly after the completion of Sun Tunnels, and along with this work she also shot the photographic composites Sun Tunnels: Sunrise and Sunlight in Sun Tunnels.
