The work consists of four massive concrete tunnels ( long and in diameter), which are arranged in an “X” configuration to total a length of . Each tunnel reacts to the sun differently, aligned with the sunrise or sunset, of the summer or winter solstice. Someone visiting the site would see the tunnels immediately with their contrast to the fairly undifferentiated desert landscape. Approaching the work, which can be seen up to away, the viewer's perception of space is questioned as the tunnels change views as a product of their landscape.
