Bloomington Minnesota USA Equatorial Dial Dial 447
An Erickson Monument polar equatorial dial of light granite, approximately 5 feet in diameter and 6 inches thick. The gnomon shaft is steel, 3 inches in diameter, extending from the ground through the dial plate and outward another 18 inches. The base is a simple tier of raised concrete. 24 hours of radiating lines are inscribed on each side of the dial (summer and winter), ending with the hour in Arabic numbers. Time is graduated by half-hour and 5 minute marks. Two equation of time graphs, each about 3 x 5 feet engraved in granite, are set at the north and south ends of the dial, providing corrections from Apr-Sep, and Oct-Mar. [The description to obtain watch time attributes Bloomington's longitude as 93:18 East instead of West. Further, it tells the user to subtract one hour for daylight savings time.] Nearly identical to the Port Arthur Dial, Texas, but without city names located in various time zones. Compare this dial with other Erickson dials
Port Arthur Texas USA Equatorial Dial Dial 446
A large Erickson Monument polar equatorial dial of light colored granite, approximately 6 feet in diameter and 6 inches thick. The gnomon shaft is steel, extending from the ground through the dial plate and outward another two feet. The base is a simple tier of raised concrete. 24 hours are inscribed on each side of the dial (summer and winter) as radiating lines with Arabic numbers at the end. Time is graduated by half-hour and 5 minute marks. Two equation of time graphs, each about 3 x 6 feet engraved in granite, are set at the north and south ends of the dial, providing corrections from Apr-Sep, and Oct-Mar. [An interesting note about the engraving for the Apr-Sep graph: The line originally said "For daylight savings time, subtract one hour", the word "subtract" was filled in and "you add" was inscribed over it.] In the top quadrant of the dial (both obverse and reverse) where the sun's shadow will never cast, are the names of cities in 16 different Time Zones. A beautiful and well-crafted sundial, it makes a fitting Seaman's Memorial.
Lewisburg Pennsylvania USA Cylindrical Dial Dial 445
A large, ornate equatorial dial of brass sits outside the physics department building. The dial is approximately 8 feet across. Two pillars with brass balls support the dial plate. Two more pillars with ball support the gnomon wire. To add a flourish, the north most pillar and ball have a spread eagle holding the gnomon wire in its mouth. Unfortunately this beautiful dial is tarnished by age, with the analemmas for each hour barely visible on the dial plate. The gnomon wire, broken sometime in the past, is jury-rigged and tied together in the middle, resulting in a unkempt look to such a fine dial. A dark, round stone base, perhaps made of slate, approximately 8 foot in diameter supports the dial and pillars. The stone sits upon a 10 x 10 foot concrete pad.
Wilmot Ohio USA Horizontal Dial Dial 444
The Wilderness Center Sundial is large horizontal dial with a 6-foot steel gnomon approximately 27 inches thick. The base is done in slate with copper numbers.
Newburyport Massachusetts USA Armillary Sphere Dial 443
This 4-foot diameter armillary sphere is made of galvanized, painted and gold leafed steel. The dial is had forged and welded by Cassidy Brothers Forge. It was "Colorgalvanized" by Duncan Industries and gold leafed. It was made to specifications from Albert Waugh's book on sundials, including latitude and longitude corrections. The sundial is mounted on a cast stone pedestal and stands about 8 foot high.
Watertown New York USA Vertical Dial Dial 442
The vertical dial is on one face of a ornamental rectangular display raised on pole at the edge of the street at Key Bank Clock Plaza. The dial is approximately 2-foot square with an ornate gnomon having a "key" cutout. The dial was moved from another location to the present pole and restored. The dial is made of copper or bronze. Nearby is a plaque with the equation of time. Dedicated May 15, 1967.
Somerville Massachusetts USA Vertical Dial Dial 441
This 5 foot x 7 foot vertical dial is painted onto the true south facing concrete wall of a commercial building. The gnomon and hour lines appear to be weathered copper or bronze. The hour lines are corrected for longitude, but may be in error by about 5 minutes. The dial is in relatively good condition, but the painted numerals are fading. The building itself has been in several hands over the last 10-15 years.
Black Rock City Nevada USA Sculpture/Artwork Dial 439
The Pyrolarium was a sundial designed for the Burning Man Festival (1999) to shoot exploding mortars into the sky at each hour of the day. The structure was 12 feet in diameter and nearly 18 feet high. On an upper platform out of the reach of people were a series of tubes loaded with black powder. Around the perimeter of the platform were a set of Fresnel lenses, igniting them in succession throughout the day. The last mortar ignited at sunset and the Pryolarium was incinerated, as is the custom of all artwork displayed at the Burning Man Festival.
Pittsford New York USA Vertical Dial Dial 438
This old vertical north facing dial in on the Spring House, constructed circa 1822. The building was an old Erie Canal Inn. The dial is about 48 inches high by 30 inches wide, made of wood and painted with a white boarder. The gnomon is also white painted wood and "looks upside down" because the dial faces north. The dial and gnomon have been repainted several times.
Hollidaysburg Pennsylvania USA Horizontal Dial Dial 437

Toronto Ontario Canada Horizontal Dial Dial 435
A small bronze 8 inch diameter horizontal dial, sitting upon a granite column of equal diameter. The dial plate has simple radiating hour lines and Roman numerals. No minute or quarter hour marks. The gnomon may have broken off at some time and been repaired, since it is now held on by a rather unsightly bronze angle iron.
Jersey City New Jersey USA Horizontal Dial Dial 434
A horizontal dial 12 feet across made of concrete and pipe.
Toronto Ontario Canada Horizontal Dial 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.

East Hartland Connecticut USA Noon Mark or Meridian Dial 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 Obelisk or Vertical Gnomon 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 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 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.

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 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 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 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 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 Sun Alignment Dial 418

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.
Toronto Ontario Canada Equatorial Dial 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. The gnomon is held by semi-circular arc with pleasing proportions that match the equatorial arc.

In the hinge, visitors are given a small altitude card dial that tells Eastern Daylight Time from June - Oct. Admission fee.
Starr's Point Nova Scotia Canada Horizontal Dial Dial 407
A small horizontal dial, 8-inches in diameter. The dial is a fiberglass reproduction with metal gnomon upon a cement pedestal. The original dial dates from the 1820s and judging from the reproduction, is in very poor condition. Has Roman numerals, but the hour lines do not agree with the gnomon position. Very difficult to read. North edge of gnomon is cut to resemble a face in profile, possibly in reference to the inscription. On the grounds of the Charles Ramage Prescott House, built 1814 - 1816. Prescott was a merchant and horticulturalist.
Windsor Nova Scotia Canada Horizontal Dial Dial 406

Plaque on wall reads "The sundial at the top of this wall is a faithful reconstruction of the original which Frederictonians used during the 1800s and early 1900s. The shadow cast by the gnomon (style) onto the dial accurately displays local apparent solar time." An equation of Time is included on the plaque to determine mean time. The date of the original construction of this sundial is not known, but the Soldiers Barracks were built in 1826. The dial was restored in 1992.
St. Louis Missouri USA Vertical Dial Dial 396
A vertical decliner at the top of the Cupples I building. Given by the class of 1908. Can be seen from the courtyard of Robert S. Brookings building. In 1908 the campus newspaper, the Washington University Student Life, commented that "The new sun dial on Cupples I is now being put into position upon the tablet on the south side of the building?It will be interesting to note the discrepancy between sun time and standard time by comparing with the Varsity clock [a large time piece situated high on the west wall of Brookings Hall, with both clock and dial visible in the quadrangle]." Today the Baumont Pavilion, erected in 1965, blocks a close view of the ornate tablet and dial. Use binoculars from a distance.
