One of the few women associated with the male-dominated form of Land Art, Nancy Holt said that the idea for her Sun Tunnels—a work made up of four huge concrete cylinders—came “in the desert watching the sun rising and setting, keeping the time of the earth. Sun Tunnels can exist only in that particular place—the work evolved out of its site.” That site is in a remote valley in the Great Basin Desert, outside the ghost town of Lucin, Utah, west of the Bonneville Salt Flats. The cylinders are arranged in a cross and aligned to frame the sun at sunrise and sunset during the summer and winter solstice and are pierced with smaller holes representing the stars of four constellations: Draco, Perseus, Columba, and Capricorn.

• All mechanical watches and clocks have a movement that accurately - oscillation of. aewight
• this mechanism is affected by gravity
• Gyro mechanism evenly distributes the effects of gravity pull to ensure that no part of the movement is affected more than any other
