An artwork by Nancy Holt, completed in 1976, consisting of four large concrete tubes, laid out in the desert in an open X configuration. The nine foot diameter, 18 foot long "tunnels" are pierced by holes of varying size, that correspond with the pattern of selected celestial constellations.
There is a tunnel for Draco, Perseus, Columba and Capricorn. [http://ludb.clui.org/ex/i/UT3126/]
