Equatorial Dial |
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. |

| A 51 x 36 foot horizontal dial with a 21 foot welded silicon bronze gnomon standing 14 feet high. The hour lines are copper inlaid in concrete and the hour markers are 4 inch high bronze Arabic numerals. At solar noon, sunlight passing through a slit in the gnomon illuminates the noon marker with a line of sunlight while prisms on the end of the gnomon project rainbows onto this line of light, making the sculpture a seasonal calendar as well as a way to tell time.
Created by sculptor Robert Perless, Sun Dagger functions as a unique celestial observatory to amplify the synergy of man and nature. It also works as a seasonal calendar, celebrating the winter and summer solstices and the vernal and autumnal equinoxes with rainbows crossing the line of sunlight from the gnomon slit and falling on inscribed plaques. |

| "Rising Rings" is a cast iron band 11 feet high by 17 feet in diameter with a hole that casts a beam of light onto a central ring monument on the equinoxes. The dial was commissioned by Dr. Swraj Paul, a steel mill owner, to honor his daughter Ambika who died in 1968 of leukemia at age four. This monument honors the inspiration her joy of life instilled in her father. At the central of the dial is a cast iron ring that holds a bronze image of her that is illuminated for several days twice a year. On two dates, Ambika's birthday and the anniversary of the mill's re-opening the noon sunlight passes through the circular opening in the larger ring and strikes markers on the inner ring. Miklos Simon created the portrait of Ambika mounted on the smaller ring. |

| When is a bridge not a bridge? When it's almost a sundial. The 217 foot high suspension span called Sundial Bridge wants to be a sundial, and has come very close. The suspension pylon is aligned true north, but unfortunately performs as an inaccurate gnomon with an inclination of 49 deg (for bridge functionality) rather than for the 40.6 deg latitude of the site. The bridge is 700 feet long and weighs 1,600 tons. Funding for the bridge comes from the McConnell Foundation, Redding Redevelopment Agency, Federal Highway Administration, and Turtle Bay Exploration Park |

A small horizontal dial about 8 inches in diameter with a triangular brass gnomon tells Daylight Saving Time using Roman numerals. Then a larger gnomonic dial is inscribed on the remaining surface, telling time from the shadow of the tip of the triangular gnomon. The gnomonic dial has hourly analemmas,telling time using Arabic numbers in Standard Time. Both dial lines are offset for the longitude of 70 degrees west. The gnomonic dial has declination lines for each month. A small analemma on the meridian has the letters of the months, indicating how to read the hourly analemmas depending upon the date. The dial is built to be read from the north, so the user's shadow does not interfere. |

The finished dial has been set in desert plants, native to the region, including: Candelilla, Gobernadora, Lechuguilla, Sangre de drago, Huevo de toro, Biznaga, Pitaya, Corona de espinas, Nopal rastrero, and Cardenche. These are all protected desert species. The dial has a compass rose and six disk-shaped maps at the east and west sides to show the course of sunrise/sunset across the Mexican Republic on the solstices and equinox. |

Dial 505 |
| A 90 inch diameter spherical segment equatorial dial ten feet high of masonry construction with 3D fiberglass analemmic gnomon 40 inches long. Dial terrazzo face has hour, half-hour, quarter-hour and 5-minute marks with Roman hour numerals for PST. The 5-minute marks are one inch apart. Dial face includes analemma graphic with month dates; a plaque describes how to use the analemma graphic to select which side of the gnomon shadow to use to read time. Base perimeter has 12 ceramic plaques with Zodiacal signs.
Indicated time is accurate to one minute throughout the winter and to five minutes in summer. This is remarkable because the dial is located just outside a children's playground and children routinely climb on the dial and swing from the gnomon. An animation from digital images showing the gnomon shadow motion over the course of a full year is available.
Dedicated as the Ralph B. Larkin Memorial Sundial. Rev. Larkin was a retired missionary who taught science to children for 17 years in Claremont. Dr. Larkin's father was Edgar Lucien Larkin, Director of the Mt. Lowe Observatory above Los Angeles 1900-1924 using a 16-inch Alvan Clark refractor telescope, described by Alvan Clark as, "the finest telescope I ever made." Ralph Larkin often said, "I grew up with a telescope." The Mt. Lowe Observatory was destroyed in a windstorm in 1928 and the Alvan Clark refractor was moved to Ricard Observatory at the University of Santa Clara, California. |

Dial 504 |
| A gnomonic horizontal dial constructed in bright colors on a 20 by 14 foot concrete pad. The gnomon is a vertical steel pipe 1 meter tall with a small nodus at the top. Hour lines are marked within summer and winter solstice and equatorial lines. The dial is marked with both standard and daylight local solar time. The noon line is complemented by its analemma with the months labeled. The sundial is used by Sunnymead School to aid in the science curriculum. The sundial was designed and created by Michael Folsom-Kovarik as an Eagle Scout project. Construction began on July 20, 2002 and ended on June 28, 2003. Michael was approached by Paul Stockman (the Home and School Association's treasurer) with the idea of building a sundial at Sunnymead School. Michael then came up with the design (made to keep the sundial as a useful teaching tool for the entire school day no matter what time of year) and location. After a year and a half from planning to completion, Sunnymead Elementary has a working and accurate sundial! |

Around the circumference of the dial are Arabic number placards for each hour from 6am to 6pm. The flowers are changed seasonally for a gardener?s delight, and during the winter when the plants are dormant, the gnomon is removed and the area is used for a winter light show. |

Horizontal Dial |
Dial 500 |
| An old horizontal dial approx 60 cm diameter. From 1914-1967 was located at Marksheffel Garage, relocated to Monument Valley Park in 1967. The builder may have been van Briggle Pottery, but its history is more complex: The angles of the hour lines are consistent with a latitude of 43.9° (roughly) but the present location is 38.9°. A gnomon (probably not original) was cut for 34° lat, but has now been corrected. Likewise, the whole dial had to be rotated to true north, being off by some 47°. Hour lines have eroded, and those before 6am and after 6pm radiate from the wrong side of the gnomon. The city has spent a considerable amount of money cleaning up the area, removing the shrubs that blocked sunlight and building a nice brick wall with flowerbeds, so the area looks better, but the dial is worse than ever, with vandals bending the gnomon. |
