Sun Tunnels

The Sun Tunnels are located in Utah's remote Great Basin Desert, specifically in the northwestern part of the state. They are situated in the Great Salt Lake Desert, accessible via long stretches of dirt and gravel roads. The remote location was intentionally chosen by Nancy Holt to highlight the vastness of the landscape.

The four massive concrete cylinders are arranged in an open cross configuration, precisely aligned with the rising and setting sun on the summer and winter solstices. During these specific days, the sun perfectly aligns with the center axis of the tunnels. This allows visitors to view the sun framed perfectly within the concrete structures.

Yes, the top half of each concrete cylinder is pierced with a series of strategically placed holes. The holes correspond exactly to the magnitude of the stars in four specific constellations: Draco, Perseus, Columba, and Capricorn. During the day, these holes cast dynamic, shifting patterns of light and shadow inside the tunnels.

Yes, the Sun Tunnels are located on public land managed by the Bureau of Land Management and are open to the public year-round. There are no entrance fees or fences, making it freely accessible to anyone who can make the drive. However, because it is a harsh desert environment with no facilities, visitors must bring their own water and supplies.
