Toronto Ontario Canada Horizontal Dial 433
A striking 30 inch diameter horizontal dial. The equation of time correction is made by a slight rocking of the gnomon about the polar axis, controlled by a manual date index and a hidden cam mechanism. At the south end of the gnomon on the dial is a sunburst design. The octagonal pedestal is ornately covered with six copper plates. Each showing two zodiac signs in relief, forming a frieze 20 inches high around the pedestal.
 
 
Fairfax Virginia USA Equatorial Dial 432
This bronze equatorial dial is about four feet in diameter with a 6 inch equatorial band containing raised Roman hour numbers from 5am to 7pm. The band is graduated every ten minutes and is offset by approximately 8 minutes to read Eastern Apparent Time. The gnomon is a simple arrow without nodus and the dial does not have an analemma. The octagonal dial base is made of brown marble panels approximately 5 feet high with a smaller octagon on top approximately 1 foot high that supports the dial. Each octagon is capped with thick granite. The base is a mausoleum, with alternate octagonal sides each containing 8 crypts.
 
 
Wellesley Massachusetts USA Horizontal Dial 431
A small 14x14 inch rose granite square dial with an unassuming 5 inch high brass gnomon sits upon a round white 3 foot high granite column. At the base is a larger granite block. Built about 1899.
 
 
Kalamazoo Michigan USA Analemmatic Dial 430
A modernistic analemmatic dial. The ellipse is a raised stone wall with large Arabic numbers for each hour from 5am to 7 pm. The concrete patio in front of the wall contains the analemmatic line of months as an indicator of where to stand for casting the shadow.
 
 
East Hartland Connecticut USA Noon Marker Dial 429
This upright stone was originally a noon marker at Nathaniel Taggart's inn in colonial North Blandford, MA. The stone was moved by Taggart's granddaughter Polly Taggart Church to Harland, CT, where she lived following her marriage. In 1935 the stone was set up in the Hartland Cemetery, casting its noon day shadow onto a flat stone with an engraved meridian line.
 
 
Sebastopol California USA Vertical Obelisk Dial 428
This is a vertical obelisk 3 foot on a side and 9 foot tall. It is more of a sun calendar than a sundial. The tip of the obelisk's shadow is tracked by marks on a concrete pad on the ground. The summer and winter solstices and equinoxes are indicated by tiles set in the pad.
 
 
Newcastle Maine USA Horizontal Dial 427
A small horizontal dial with an interesting history. In 1997 when the dial was installed, the following is quoted of designer and builder Jim Estey: "We set it by our watches," Jim said, and then glued it down to its stand. That means it cannot be reset when the sun and time changes, but visitors will have to compensate."
 
 
Portland Connecticut USA Horizontal Dial 426
An 18x18 inch square horizontal sundial with ornate engraving. Along the edge are Roman numerals telling the hours. The gnomon is equally ornate. Both dial plate and gnomon are made of brass. Dial sits on a tapered granite pedestal with a square granite cap.
 
 
Nashville Tennessee USA Vertical Dial 425
A 6 x 7 foot vertical dial declining 16.4? east of south sits above the entrance to the Science Building. The dial shows hour lines, declination lines and a noon analemma.
 
 
San Carlos California USA Vertical Dial 424
This vertical dial is approximately 4 foot high by 6 foot long, mounted on the end wall of a house that can be publicly viewed. Dial has hour lines and lines marking the equator and solstice shadow limits. Made of wood and brass.
 
 
Berkeley California USA Statue Dial 423
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. Access by admission to the Hall of Science museum
 
 
Berkeley California USA Horizontal Dial 422
At the edge of the bay is a round horizontal sundial about 10 feet in diameter with a stark triangular gnomon. Both gnomon and dial base are of hammered concrete. The base rises above the ground by about 2 feet where Arabic numbers encircle the dial to tell the hours. The dial face is not quite level, perhaps to help with water runoff.
 
 
San Francisco California USA Vertical Dial 421
Dial is on an outside wall above the entrance to a private residence. The dial was designed by Stan Musilek. The dial back is made out of galvanized steel. Metal rails indicate the hours. Instead of Arabic or Roman numerals, the proper number of steel balls indicate the time of each hour. Overall, the dial is 4 by 6 feet.
 
 
San Francisco California USA Horizontal Dial 420
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.
 
 
San Francisco California USA Horizontal Dial 419
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.
 
 
San Francisco California USA Stone Sculpture Dial 418
This is a 16 ton granite statue by Richard O'Hanlon entitled "Sunstone I" and was designed in collaboration with astronomer David Cudaback. A small wall of rock with a round inlay of dark stone is supported high upon two tall vertical slabs of granite. At the back is a "heel stone" with marks to show where the sunlight strikes at the Equinox and Solstice.
 
 
San Francisco California USA Horizontal Dial 417
A plain but nicely done brass horizontal dial about 2 feet in diameter mounted on a simple concrete pedestal. The dial is in good condition, but about 50 degrees out of alignment.
 
 
Manchester Vermont USA Vertical Dial 416
A beautiful vertical declining dial, done in white lines and numerals on the side of a red barn. Made of metal and wood, the overall height is about 15 feet. The dial has a clean, modern design using tapered hour lines and simple gnomon. The Arabic numerals for each hour are graded in size to match the size of their hour line, with the largest at noon and the smallest at 8am and 5pm. The Manchester Journal reported that "the sun clock was installed the day before Thanksgiving 1999, with final adjustments being done just as the sun went down."
 
 
Lincoln Nebraska USA Equatorial Dial 415
The Carroll Moore Memorial Dial is an equatorial disk dial built by Cold Spring Granite Co. The granite base weighs 6,270 lbs. and is about 6 ft. in diameter. The granite dial plate weighs 3,420 lbs. and is 5 ft. 8 in. in diameter. The stainless steel 5 inch gnomon rod weighs 200 lbs and is approximately 6 feet long from end to end through the equatorial disk. The dial face has hour marks for all 24 hour hours, placed for symmetrical effect rather than for practical time telling. The hours are rotated slightly to account for longitude so that 12:30 is the nearly vertical hour line. Web site has pictures of dial construction.
 
 
Toronto Ontario Canada Equatorial Dial 414
An equatorial dial with rod gnomon bent into a half analemma. Raised Roman numerals along the equatorial arc from V in morning to VII at night. Gnomon held by semi-circular arc with pleasing proportions that match the equatorial arc.
