Big Bay Ontario Canada Analemmatic Dial Dial 467
This is a nicely constructed analemmatic dial, made of concrete, stone and ceramic tile. The hour markers are a series of small posts set in a continuous elliptical path with a 6 meter major axis and 4 meter minor axis. The sundial is located in a field next to a megalithic henge at Keppel Croft Farm and Gardens.
 
 
Thunder Bay Ontario Canada Analemmatic Dial Dial 466
A very well constructed analemmatic dial about 24 by 11 feet. The dial may be difficult to find, since it is in the center of a field that is devoted to wild grass of the area. Cement markers are used to show the hours and for the central base showing the months where to stand. The hourly markers are corrected for the longitude of Thunder Bay. The site is visited quite frequently by school children and is a great educational tool for dialing.
 
 
Tucson Arizona USA Horizontal Dial Dial 465
A simple square horizontal dial 20 x 20 inches carved in a 3 inch block of granite with a bronze gnomon. The dial has hour lines from 6am to 6pm for local solar time. No graph or table for longitude and Equation of Time corrections. Dial sits atop a 3 foot square pedestal.
 
 
Tucson Arizona USA Horizontal Dial Dial 464
A horizontal sundial 45 x 61 inches with a monofilar brass cable gnomon and tension counterweight. This is the largest horizontal sundial in the US carved on a single piece of stone, taking two years to build. The dial has hour lines from 5am to 8pm, corrected for longitude. Each hour line has an analemma and in the lower right of the dial is a graph of the Equation of Time. A nodus on the wire gnomon indicates date, with declension lines for summer and winter solstice, equinox, and date lines. Time and direction of sunrise and sunset are marked on the equinox and solstice lines. At the base of the gnomon is a 16-point compass rose. On the left side of the dial is a table for telling time by moon shadows. In the center is a copy of the hands from "The Creation" by Michelangelo.
 
 
Ithaca New York USA Horizontal Dial Dial 463
A horizontal sundial made from a an irregular slab of stone approximately 18 x 24 inches. The hour markings are inscribed in the form of an arrow pointing to the 12 o'clock hour and the gnomon is a thin blade. In keeping with the herb garden's design, maker and designer Michael Sweeney used native materials of stone for the dial and pedestal. The dial base was a prized antique millstone of orange granite from a nearby village.

Casa Grande Arizona USA Horizontal Dial Dial 457
This horizontal dial is an engraved flagstone approximately 40 inches in diameter designed by John Carmichael. The monofilar gnomon is a stranded brass cable that extends upward to a height of 15 inches and is held taught by a rock counterweight. The engraved stone shows time marks to 5 minutes, corrected for longitude. Time and direction of sunrise and sunset for the equinoxes and solstices are also given.
 
 
Tucson Arizona USA Vertical Dial Dial 456
This is a 10 x 10 foot south vertical wall dial with hour lines painted on the wall that are corrected for longitude. A unique feature of this dial is the time scale can be rotated forward or back slightly to compensate for the Equation of Time. However, because only the hours are marked, precise minute reading is difficult. Welded steel was used to make the time marker ring and gnomon.
 
 
Halifax Nova Scotia Canada Horizontal Dial Dial 455
This bronze horizontal dial is approximately 25 cm across on a one-meter high pedestal. Both the dial and dedication plate have a blue-green patina. The gnomon is slightly bent and appears to have been re-attached to the dial. The orientation remains true. Roman numerals mark the hours from 5 am to 7 pm. Hour lines plus half-hour marks. The concrete base is badly cracked and small pieces have fallen away. The dial is well-situated in an open area, but a nearby tree might shade the dial near midday during fall, winter, and spring.
 
 
Juneau Alaska USA Analemmatic Dial Dial 454
Painted on a downtown sidewalk is an analemmatic sundial for public use. The 25 x 20 foot sundial was organized as a community project. Eden Orelove, niece of designer Michael Orelove said, "We wanted to get as many school classes and local volunteer organizations involved as possible." Groups were invited to join the project by painting the hourly numbers. Two concentric ring of numbers are used to indicate both standard and daylight saving time, which extends from 4 am to 10 pm.

Kingston Ontario Canada Vertical Dial Dial 450
A square pillar of limestone rocks 4 foot on a side and 15 feet high with a small bowl and sphere on top hold two vertical dials each 2x2 feet. The pillar faces are oriented SE and SW allowing for two declining dials. The dials are of solid brass and have hour lines with Arabic numbers in a modern design belying by the stonework of the pillars. Unfortunately the 14-inch gnomons are bent
 
 
Ottawa Ontario Canada Globe or Hemispheric Dial 449
This hemispherium dial is a dramatic modern sculpture. The 32 inch quarter hemisphere is carved into the edge of a 40 inch cube of dark granite tilted to conform to its latitude of 45.5° , and set upon a rough concrete pedestal of slightly smaller dimension. The gnomon is a
 
 
Calgary Alberta Canada Equatorial Dial Dial 448
A steel and brass equatorial dial 49 inches in diameter. The dial simulates an armillary sphere with two crossed semi-circles in a modernistic sculpture. There is a slot in the gnomon that projects a sun line and corrects for the equation of time; the gnomon is turned over at the solstice. Fine adjustments are required near the solstice to show correct clock time (MST). Dial built as a Canadian Centennial Project. Now relocated to a mid-level landing on the entrance stairs but not correctly aligned, producing a 48 minute error.
 
 
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.

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.

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.
 
 
Fairfax Virginia USA Equatorial Dial 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.

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 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.
 
 
Nashville Tennessee USA Vertical Dial Dial 425
A 6 x 7 foot vertical dial declining 16.4 deg east of south. The dial of limestone is integral to the building with a near square face, engraved lines and a small triangular gnomon. Hour marks are from 6am to 4pm, labeled between long hour lines. Solar declination lines are shown as dotted lines for the zodiac, including solstices and equinox. This dial was on the 2022 NASS Conference dial tour of Nashville.
 
 
San Carlos California USA Vertical Dial 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 Sculpture/Artwork 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 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
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 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.
