Culver City California USA Equatorial Dial 536
Located near the edge of a hill in Culver Park, this dial commands a fine view of the surrounding communities. The equatorial dial face is a six foot diameter, six inch thick brass ring supported by a 24 foot long steel gnomon six inches in diameter. 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. A bronze plaque states time is read from the center of the gnomon shadow and briefly discusses the equation of time. The dial is not longitude corrected and indicates local apparent time.
