The gnomon is anchored in a concrete oval-shaped base covered with tile and mosaics. The base and three surrounding water-drop shape ovals are inscribed with the word "Time" in the 12 languages spoken in Culver City. Ballona Creek, visible from the sundial, once provided transportation, food and recreation for a thriving native American population and later for Spanish-origin ranch owners. The dial north face has the 1:00 hour line at the bottom for Daylight Savings Time while the south face has the 12:00 hour line at the bottom for standard time.

Created by sculptor Robert Perless, Sun Dagger functions as a unique celestial observatory to amplify the synergy of man and nature.
