This is a large granite statue by Richard O'hanlon entitled "Sunstone II" and was designed in collaboration with astronomer David Cudaback. A north-south large polished granite slab has the top cut at the latitude of 38 degrees to sight the North Star. A hole in the stone allows east or west viewing, with limiting angles designed to show the extent of maximum planetary and lunar wandering. An east-west stone crosses the north side of the granite slab, allowing light to pass only at noontime onto a heel stone with marks for Equinox and Solstice.

Dial 734 |
A large vertical dial on an east-declining south stucco wall of an elevator tower in the parking lot of McClellan Airport. The gnomon, hour and declination lines and Arabic numerals are stainless steel. The dial design is flawed, incorrect for either a point-in-space nodus dial or a polar-inclined gnomon dial. The installed gnomon is horizontal but if intended to support only a nodus, the location is wrong; the nodus shadow is outside the lower declination line in the photos. The hour lines radiate from the gnomon base as for a polar-inclined gnomon; they should radiate from a point much higher if for a point-in-space nodus. |

Equatorial Dial |
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. |

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. |

This colorful analemmatic dial is an opening of the garden path made of decomposed granite. The sundial is 18 feet wide in the E-W direction and just a bit more than 9 feet in the N-S direction. Tile hour marks go from 6am to 7pm, with an additional tile above the 12-noon saying "PST" (Pacific Standard Time). Since there is no longitude correction, the sundial actually shows local solar time. But a nearby plaque with the Equation of Time allows the user to determine true civil time. Bailey Points for showing the direction of sunrise and sunset have not yet been included. The central walkway is made of colorful tiles, with each tile representing one month that is clearly labeled. |

Horizontal Dial |
Dial 1076 |
Farenholt sundial for U.S. Naval Hospital Mare Island. Cast bronze, 18 inch (46 cm) diameter circular face, mounted on a cement pedestal 40 inches tall. Only three Farenholt sundials are known to have Spanish mottos: Mare Island is one of them. (Sunnyvale, CA and Hawthorne, NV are the others). We notice other difference from the classic Farenholt sundial: (1) there is no true chapter ring for the hour marks. They are at the end of long hour lines that extend from 4am to 8pm. All other dials are from 6am to 6pm. (2) The hours are delineated in quarter hours. All other dials are delineated in half hours. (3) The gnomon foot is considerably below center (and appears restored) with a raised style edge that is more “art deco” than the curves of other Farenholt gnomons. (4) The naval command is not spelled out. Rather, just the initials “U.S.N.H.M.I”. All other Farenholt dials spell the naval command in full. (5) The date is placed above the command initials. All other dials have the date below the naval command title. (6) There are no Farenholt initials on the dial’s southern edge. All of this may indicate the haste with which the dial was made, perhaps to memorialize those that died in Vallejo due to the 1918-1919 influenza epidemic. |

Analemmatic sundial 16' x 10' (4.8m x 3m) painted as a full ellipse on the driveway to a house. Shows local solar time. Time corrections to obtain civil time (Equation of Time and longitude offset) are given for the first of each month on the Zodiac Walkway. Sunrise and Sunset sighting points (seasonal or "Bailey" points) are provided for a theoretical horizon, but are not useful as the dial site is within a valley. The perimeter of the ellipse is marked with great circle navigation directions for a selection of historical solar and celestial observatories, especially for North America, but all historically inhabited continents are represented. A QR code is provided for a link to a website with instructions for the dial, reference links on sundials (including NASS), and links for the selected observatories on the perimeter. The 2 degree slope of the driveway was not compensated for in the sundial layout, but the dial is unshaded from roughly 9:00 am to 5:00 pm in the summer. |

Bronze sundial sculpture by Robert Paine. The sundial was donated to University High School in 1927 by Sara Bard Field in honor of her son Albert, who was killed in 1917 in an automobile accident. Albert was the high school senior class president in 1917. His mother Sara was a leading suffragist on the West Coast. The High School has been renovated and now used by Children's Hospital Oakland Research Institute (CHORI).
The sculpture is of a boy holding a shield and an arrow. The arrow casts a graceful shadow onto the level shield. The sculpture is about 30 inches high. The base is stone, probably a jade. |

One of Bill Gottesman's unique-design Renaissance dials of cast and structural bronze with a 27 inch diameter helix with a celestial-north aligned axis. Time is told by a focused beam of light that moves around the helix throughout the day. The light beam is reflected from a long cylindrical unsilvered mirror in a structure that supports the helix. A sliding time scale within the helix can be adjusted for EOT and DST and includes longitude correction. Once this scale is adjusted for date, the dial shows civil, or clock, time. The dial base is cast bronze allowing adjustment for latitude and placed on a concrete pedestal. |

A vertical declining dial approximately 45 x 55 inches. Made of aluminum and brass. Shows the hours from 8 am to 5 pm using analemmas. Analemmas are bounded by the summer and winter solstices and a straight line through them shows the equinox. Daylight time is shown using Roman numerals, with standard time shown in Arabic. In keeping with the motto, a simple equation is written on the dial face, d/dt is not equal 0.
Designer Ronald Bracewell used an oculus, a disk with a central hole, standing 8 cm in front of the dial face. The disk casts a shadow with a bright sunlight dot to indicate both time and season. Hour lines include longitude correction.
This has been relocated; it was previously hanging free below a south facing wall, facing the Terman Engineering Building. Dial is now located on the wall of a covered walkway area. |

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 60x40 foot vertical dial of stucco, wood and brass, filling the south exterior wall of the building. Roman hour numerals show PST; Arabic hour numerals show PDT. Summer and winter solstice and the equinox lines are shown; the shadow of a nodus on the gnomon indicates the date.
Dr. Nordgren explains that the shadow of the 10-inch diameter nodus "is just the right size to take into account periods when sundials are fast or slow relative to clock time. When dials run their slowest, the leading edge of the nodus shadow gives the accurate time. During periods when dials run their fastest the trailing edge gives the accurate time."
Dr. Nordgren was among the seven designers of the sundials used on the NASA Mars Rovers in 2004. |

A 6 foot wide x 5-foot high burnished stainless steel equatorial sundial. The meridian arc is parabolic shaped and the equatorial arc is slightly more than a gracefully tapered half-circle 5 1/2-feet in diameter. The central elliptical gnomon plate, which swivels to face the sun, has an analemma cutout that casts an accurate civil-time shadow onto the equatorial ring below. The gnomon plate is laser-etched with the analemma, months and 365 days of the year, and marks for the equinoxes and solstices, and instructions. The equatorial timeline is laser-etched with hour and minute marks from 6:30 AM to 6:30 PM. The sundial body rotates and locks in position for either Daylight Saving or Standard Time. The sundial is highly accurate compensating for longitude (the equatorial ring is rotated 5min 24 sec early to measure solar time on the pacific meridian) and equation of time (by reading the east or west edge of the analemma plate gnomon shadow). The sundial often indicates clock time to within seconds and the date to within a portion of the day. A stainless steel base cover encloses the mounting hardware beneath. |

This is a monumental horizontal sundial that from the ground simply looks like a giant pole with a slanting beam. High above the ground that beam is actually a segment of a gnomon, casting its shadow on the concrete plaza below. Then, if the eye is discerning, the concrete alternates in light gray and darker gray motif for the hour sections. From space (or Google Earth) the layout of the hour angles is clearly visible, radiating from a point considerably south of the gnomon pole, showing the hours from 9AM to 3PM local solar time. Hour line plaques extend from 10AM to 7PM. |

The dial was placed within the circular lawn directly in front of the school's main entrance at the intersection of Park and El Cajon Boulevards. |

A small 10-inch cast iron dial from England honors Shakespeare in a garden of the same name. The dial is on a small pedestal in the middle of the courtyard walkway and surrounded by trees. Lovely, but many shadows pass over the dial during the day. The dial plate was made for latitude 54 degrees. The gnomon appears to have been cut down to accommodate the 38 degrees for San Francisco. This "hack" method of correcting a sundial does not give correct time. |

Hilltop Park was built by the San Francisco Redevelopment Agency in 1987. The Landscape Architect was Michael Painter and Associates. Here is a giant sundial 70 feet in diameter with a bright yellow painted steel gnomon 78 feet long. The dial has a cement base and was designed to be used as the stage for a surrounding amphitheater. Dial shows wear and abuse, with graffiti covering the lower portion of the gnomon. Still, it is awe inspiring. |

Built in 1913 as a promotion for a housing development that was once a racetrack, this dial boasted (incorrectly) that at 34 feet in diameter and a gnomon style 28 feet in length, it was the largest dial in the world. Nevertheless it gathered much publicity and newspaper articles thanks to the Urban Realty Improvement Co. The company put out a brochure "The Sundial at Ingleside Terrace with Comments on Homes" using the sundial as a lure to attract home buyers to the newly constructed residential neighborhood. On Oct 10, the same day the Panama Canal was opened, a festive gala was held at the sundial dedication attended by more than 1500 people. Photos show young girls dancing around a small pool that surrounded the gnomon. A light (visible in several early photos) dangled from the tip of the gnomon. Bronze statues of seals were originally in the pool, but by 1920 the pool was filled with concrete and the seals were gone. Today the pool area is painted green. |

The globe is etched with the dial site at the globe's zenith. The dial has a central gnomon. When the shadow of a pointer falls on the gnomon the time is read using the correct side of the hour line analemma. |

This vertical dial has undergone a number of restorations since it was set in lime in 1889. A photograph from 1900 shows the placement of a gnomon rod is horizontal. In 1992 before the National Park Service restoration in 2012 the gnomon is set in a polar orientation. But it doesn't really matter since the hour lines are marked at nearly regular 15 degree intervals with half hour sub-marks. |

The sundial is a cement globe of the earth 28 inches in diameter inclined at 40 degrees, a bit off the site's 38' 20" N latitude. The globe is oriented with the site longitude on the upper meridian so that shadows across the globe represent the true sun angle at that moment. A rod through the globe casts a shadow onto the north polar regions in the summer. At the southern end is a small equatorial dial with hour lines from 8am to 4pm. |

Polar Dial |
Dial 1095 |
It is a polar dial using a rod gnomon. Using a template from Shadows software, the dial is made of handmade ceramic tiles mounted on an aluminum bar frame anchored to a concrete base. Brass borders define winter and summer solstice declination lines, and an aluminum bar defines the E-W equinox declination. Copper analemmas define the sun’s annual path at 7:30/8:30 PST/PDT and hourly until 5/6PM. Metal balls along the analemmas are placed the 1st of each month. Black declination lines mark the ancient Babylonian Zodiacal signs, designated by different colors. Hours are numbered for PST and PDT. Standard time on the hour, accurate to 1 minute, is read on the tile surface when the gnomon shadow is just under the analemma for that hour. The 1st of each month is marked on tiles in early AM and late PM hours, guiding which side of the analemma is used. |
