Des Moines Iowa USA Horizontal Dial Dial 976
This is an ornate 12-inch diameter bronze horizontal dial with a central sun underneath the gnomon. Surrounding the the sun is an 8-point compass rose. On the chapter ring the hours are embossed from 5am to 7pm in Roman numerals that face outward. Time is delineated every 10 minutes. The gnomon is simple but too long for the dial, extending 2 inches past the dial edge. The place where a motto might be placed is empty, awaiting a bronze insert.
 
 
Des Moines Iowa USA Horizontal Dial Dial 975
This is a 32-inch diameter horizontal dial made of stainless steel. Hour lines are engraved for every half hour and extend from summer to winter solstice based on the tip of the triangular gnomon. Hours are marked in Arabic numerals. Between the solstice limits are declination lines for the first of each month. Note that the inscribed latitude and longitude are slightly in error.
 
 
Rock Island Illinois USA Analemmatic Dial Dial 974
This analemmatic dial is 20-foot wide within a 30-foot circle, all made of colored concrete. The Arabic dial hour markers follow an ellipse from 6 am to 6 pm. The dial is decorated with a botanical and Rotary Club theme. Gears and the Rotary 4-way test are interspersed with flowers and leaves of the four seasons.
 
 
Davenport Iowa USA Horizontal Dial Dial 973
This is a 40-foot diameter sundial made only from flowers. Hours are shown from 6am to 6pm. The gnomon is made of steel and wire mesh with sweet autumn clematis growing on it. The clematis vines are kept trimmed and tied up to keep the shadow from getting too big. The gardner commented, "If I were doing it over I would use a metal piece for the shadow finger." There is a steel frame in the ground to mark the outer edge and all the divisions of where to plant the plants inside the bed. The plants in the inner area of the sundial change from year to year – in 2019 it was two colors of marigolds. Alternanthera or Joseph’s Coat are used on the outer edge by the numbers. These flowers are sheared to keep them low and compact. The numbers are planted with green Alternanthera and surrounded by a band of red Alternanthera. These flower numbers are sheared with small electric grass shears and kept about 2 inches above the red band. Other plants in the sundial garden include large “elephant ears,” cactus-like agave, alyssum, ageratum and lime green and purple nicotiana. The purple nicotiana becomes fragrant after dark, providing an olfactory as well as a visual delight for visitors watching the lights play on the fountain.
 
 
Denver Colorado USA Equatorial Dial Dial 972
Bronze equatorial dial marking hours with Arabic numerals from 4:00 am to 8:30 pm for summer and from 5:00 am to 7 pm in winter. Additional marks indicate time in 15 minute and 5 minute intervals. Noon gap to choose gnomon shadow side. Hour lines marked from leading edge of shadow. The dial may be rotated by a hand wheel at bottom of the dial to adjust for both the equation of time and daylight savings time.
 
 
Roselawn Indiana USA Horizontal Dial Dial 971
This dial consists of a fiberglass 18-foot high 36-foot gnomon in the shape of a bare tan-colored human leg. Hence the dial's name of "The Leg". The tip of the toe acts as a nodus. There are no hour lines and no declination lines. Instead, during summer months a series of hour markers are arranged on ground beneath the path of the nodus shadow.
 
 
Iowa City Iowa USA Equatorial Dial Dial 970
An 2-foot diameter dial with a wide 8-inch equatorial band. Vertical lines mark half hours from 5 am to 7pm in Arabic numerals placed at both the top and bottom of the band. Zodiac declination with month and dates engraved. The shadow nodus is held in place by a horizontal rod. Time and date marks are faint, implying that the dial has been continually polished over the years.
 
 
Summerland British Columbia Canada Equatorial Dial Dial 969
This is a standard equatorial in reasonable condition, mass produced, probably steel, about 2 feet in diameter. As at 2019, it is loose on its base and so visitors are likely to find it out of alignment. It is mounted on a rough stone pedestal decorated with strips of metal reminiscent of plant foliage reaching up around it.
 
 
Sterling Colorado USA Horizontal Dial Dial 968
This horizontal dial is 18 inches in diameter made of painted iron. Parts of the dial face have rusted. The dial is marked hourly from 6am to 6pm to 6pm using Roman numerals at the dial circumference. Hour lines are made using a series of dots. The swept-wing design of gnomon has an angle of 42.5 deg, about 2 degrees higher than the latitude. The dial sits on a limestone bolder.
 
 
Denver Colorado USA Vertical Dial Dial 967
This monumental size vertical dial consumes much of the south side of the Newman Center for the Performing Arts. The dial face is limestone and sandstone with disks standing out from the wall to mark the hours from 7am until 5pm. Two row of brass disks show the time: one circular set close to the gnomon for winter and another set at the circumference for summer. The size of the disks vary, growing in size from 7am to noon, then repeating the growing size from 1pm until 5pm. Roman numerals at 7, 12, and 5 show the hours.
 
 
Nelson British Columbia Canada Horizontal Dial Dial 966
The elegant bronze gnomon is 6 foot high with a modern interpretation of the zodiac sculptured into the lower half. The zodiac is represented by reliefs of Leo, Taurus, Pisces, Gemini, Virgo, and Sagittarius with his bow. The dial face is integrated into the plaza with a stainless steel chapter ring about 12 feet in diameter. The chapter ring has ornate grill work and Roman numerals to mark the hours. A small disk shows the Equation of Time correction in polar form with the months labelled along the circumference and EOT shown radially. The resulting graph looks somewhat like a kidney.
 
 
Denver Colorado USA Horizontal Dial Dial 965
This monumental dial has a 58 foot tall gnomon made of aluminum cladding on a steel frame sitting on a concrete base. The surrounding elliptical walkway has red sandstone lines marking the time from 6 am to 6 pm. Time may be slightly off as the time lines do not account for the change in height between the walkway and the dial base. The markers south of the 6 o'clock lines are added only to provide artistic balance and do not mark time.
 
 
Denver Colorado USA Horizontal Dial Dial 964
A 12 inch bronze horizontal dial marking quarter hours with Roman numerals.from 5 AM to 7 PM. The gnomon is about 1 1/2 inches wide and the hour lines are appropriately split at the noon marker. The dial sits on 3-foot stone plinth.
 
 
Aurora Colorado USA Gnomonic or Projection Dial Dial 963

Kelowna British Columbia Canada Shadow Plane Dial Dial 960
It is a large sculpture that acts as a shadow plane dial delineated at hourly intervals. The dial is about 3m high. It is made of mild steel with a concrete base, very precisely cut and installed. It shows local solar time, delineated at hourly intervals. Each shadow plane projects onto a small vane that has notches cut out, the number of notches indicating the hour. This dial is one of the earlier artworks by Alan Storey, a successful Canadian sculptor specializing in large-scale public art. The setting is a pleasant tree-lined courtyard at the center of the campus. in the years since the courtyard was laid out and the dial installed, the trees have grown large and cast shade on the dial. The best time to view the dial in sun is probably mid-morning, or in the winter when deciduous trees have lost their leaves.
 
 
Kamloops British Columbia Canada Horizontal Dial Dial 959
A simple horizontal dial consisting of a 6' gnomon made of black-painted steel tubes set in a circular concrete patio.The dial is located in a pleasantly laid out xeno garden (planted for arid conditions) with benches and a pergola. A riverside walk passes close by, and the whole area is designated for recreational and sports use. The gnomon is unusual for its plain industrial feel, and the use of wire mesh to fill in the gnomon's triangular substyle area. As well, the north end of the gnomon is formed by a pole that extends an extra 6' upwards, topped off by a weather vane.
 
 
Denver Colorado USA Noon Mark or Meridian Dial Dial 958
Description, a 1-inch stainless steel line set in the granite pavement marks the location of the 105th meridian in front of Union Station. The meridian line marks the center of the time zone called Mountain Time, and is 7 time zones "earlier" the Greenwich. MT = UTC - 7. Throughout the Denver metro area, Kalamath Street is the road that most closely corresponds to the 105th meridian. The current 105th meridian would have been known as the 30th meridian of the United States in the 18th and 19th century.
 
 
Indianapolis Indiana USA Armillary Sphere Dial 957
This armillary is constructed adjacent to the original American Legion Wayne Post 64 building. It is made of iron with iron hour markers in Roman numerals on the equatorial band. It has arctic and antarctic circles and a longitude band from 6am to 6pm. The 45-inch diameter sphere sits atop a plain but elegant white square pedestal and octagonal dais. On the side of the pedestal are black marble plaques etched with the symbols of the Army, Navy, and Air Force. On the fourth side is the seal of the United States.
 
 
Fort Wayne Indiana USA Equatorial Dial Dial 956
According to WPTA-21 news, "This odd looking nine thousand pound chunk of limestone is a scientific instrument, a sundial unlike any you’ve seen." It is an equatorial dial but with a parabolic shaped equatorial for telling time. The reason for the odd shape? "The shadow cast by a stainless steel bar moves across the dial face telling time not just in Fort Wayne but also half a world away in Takaoka, Japan, one of Fort Wayne’s Sister Cities. A half-size version of the same sundial in Takaoka does the same thing."
 
 
La Grange Kentucky USA Equatorial Dial Dial 955
This equatorial dial is improvised using a 13 inch diameter aluminum plate embossed with fleur de lis around the perimeter. Hour lines run from 6am to 6pm with Arabic markers only at 12 and the 6's.
 
 
Saratoga Springs New York USA Horizontal Dial Dial 954
The beautifully engraved horizontal dial plate is a reproduction of the original 1901 dial. It is inscribed with “Lat 43 degrees 5 N, Long. 73 degrees 46.40 W.” This is at slight variance from the current GPS position, implying that the dial has been moved from its original position. The dial plate is 18 inches in diameter and the gnomon has a vertical height of 8.5 inches. The gnomon and dial plate are aligned at 12 degrees west of true north. Significantly, the compass magnetic declination for this location is 13.5 degrees west of true north. This misalignment makes the dial about 30 minutes fast. This is particularly unfortunate since the inscribed dial is capable of showing time to the nearest minute. The stone table upon which the sundial rests is a reproduction of a table found in the ruins of Pompeii.
 
 
Calgary Alberta Canada Armillary Sphere Dial 953
This large armillary sphere stands about 2m tall and 1.5m wide. The dial is marked by roman numerals etched completely through the equatorial band. Large holes form the hour moment, with smaller holes for the half and quarter hours. The meridian ring also serves as support for the dial. In addition are the arctic and antarctic rings. The design of a slot mechanism allows the equatorial ring to be rotated by 15° for Daylight Saving Time. However there is no plaque for the Equation of Time correction to civil time.
 
 
Summerland British Columbia Canada Armillary Sphere Dial 952
A steel patinaed armillary sphere about 1.5m in diameter, mounted on a low boulder. The dial is marked by roman numerals etched completely through the thick equatorial band. Large holes form the hour moment, with smaller holes for the half and quarter hours. The meridian ring also serves as support for the dial. In addition are arctic and antarctic rings. A ball at the center of the dial has outlines of the continents, reflecting its status as a representation of the Earth at the center of the celestial sphere. The design of a slot mechanism allows the equatorial ring to be rotated by 15° for Daylight Saving Time. A simple Equation of Time plaque attached the boulder has explanatory notes allows correction to civil time.
 
 
Saratoga Springs New York USA Armillary Sphere Dial 951
Beautiful iron armillary sundial about 6 feet high. Painted black it has gold Roman numeral hours on the equatorial time band. On the outside of the equatorial band are the twelve zodiac motifs and stars are on the meridian band.

Davis California USA Analemmatic Dial Dial 950
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.
 
 
Providence Rhode Island USA Noon Mark or Meridian Dial Dial 949
At first glance this is a gleaming stainless steel sculpture 15 feet long by 4 feet high in the shape of a Mobius strip. Although it fits its name "Infinity Possibility", it also contains a meridian noon mark sundial. At the south end of the Mobius, high up on its curved surface is a hole to allow the noontime sun to create a beam of light that hits a lower portion of the Mobius strip. Engraved on the strip is an analemma adjusted for the longitude of Brown University that shows date and civil time throughout the year. The analemma has monthly markers and is delineated with ticks every 5 days.
 
 
Kennesaw Georgia USA Horizontal Dial Dial 948
Developers of Kennesaw Gateway Park, a new group of townhouses within walking distance of of town center, collaborated with Kennesaw State University (KSU) to design and fabricate a 9-foot tall horizontal sundial that has been placed in the circular plaza of the housing common area. Page Burch, a lecturer of KSU's Master Craftsman Program was the lead coordinator to design and fabricate the sundial gnomon.

Saanich British Columbia Canada Horizontal Dial Dial 935
The dial is simply but pleasingly decorated. The gnomon is plain. The pedestal is carved from stone taken from ruins of the Basilica of Ste. Anne de Beaupre in Quebec. The Quebec connection is indicated by the use of a Fleur De Lys on the dial face, and Napier's Scottish heritage is referenced by thistle motifs on brass accoutrements fitted to the pedestal.
 
 
Surrey British Columbia Canada Sculpture/Artwork Dial 934
The sculpture, titled "Gnomon", is a metal clematis leaf about 9ft tall and 3ft 6in wide at its widest point. It varies from about 1 in at the edge to about 4 in in the middle. The base is marked with cardinal directions and a present map of the neighborhood. There are a series of twelve 9 inch disks arranged around the sculpture set at a radius of 9 ft. The disks are positioned every 30 degrees around the circle, and at the north point, is an additional disk for "12 PST". All components of the sculpture are case iron, set into a graveled area. According to accompanying information,"Gnomon, featured in Fleetwood Park’s perennial garden, is inspired by the notion of a sundial marking time. A gnomon is the central part of a sundial that casts a shadow that marks the passage of time. This artwork tells the story of the passage of time in the growth, change, and appearance of Fleetwood’s historic community landmarks.
 
 
Vernon British Columbia Canada Analemmatic Dial Dial 933
This is a standard outdoor analemmatic dial located on a hillside allowing all-day illumination and providing good views of Vernon and the surrounding area. The layout was designed by James Kanester. Rather than acting as a "Human Sundial" this analemmatic uses a movable vertical pole that sits in a slot in the declination scale. A central figure-8 analemma curve provides an indication by date where to place the gnomon in the slotted meridian grove. The declination scale, designed and constructed by Joel Wrinch, is wooden with engraved lettering and analemma. The dial's hour marks are concrete posts, topped by glass mosaics made by local artist Connie Vetter-Johnson. Only whole hours are marked. Dial furniture includes a larger glass mosaic image of a hawk. The dial's major axis is about 22 feet, the declination scale is about 6 feet long, the hour markers are 12 inches in diameter. The hawk mosaic is about 18 inches in diameter.
 
 
Vancouver British Columbia USA Horizontal Dial Dial 932
This was once a very beautiful sundial sitting on a short concrete pedestal. Now it has a missing gnomon and the dial color is uniformly aquamarine except where the coating has been rubbed away to reveal a white substrate. Tapping the dial face makes a dull sound suggesting the dial is not metal and may be hollow. A possible explanation is that the dial could be made of some kind of cast resin or fiberglass and was then spray-painted. The dial face itself is elegantly sculpted into five sectors, showing clusters of flowers, berries and fruits, creating a pronounced 3D effect. Because of this, the hour lines are reduced to short ticks at the edge of the dial face. The dial shows solar hours, marked off using Roman numerals.
 
 
Vancouver British Columbia Canada Equatorial Dial Dial 931
A simple but elegant and well-executed bronze equatorial dial by renowned local sculptor Gerhard Class. It is about 24-inches in diameter and is mounted on a 16 x 16 x 36-inch plinth of nephrite jade, damaged at one corner. The gnomon has a central slit and can be rotated about the polar axis to create a narrow beam of light for precise reading of the sun's position. The dial shows local solar time plus one hour, corresponding to Daylight Saving Time. The dial's construction is technically perfect but, sadly, the dial appears to be misaligned with the gnomon axis pointing 7 deg west of north.
 
 
Burnaby British Columbia Canada Equatorial Dial Dial 930
This substantial and durable 30 inch anodized aluminium equatorial dial is mounted on a concrete plinth with a brass plaque showing the Equation of Time and usage instructions. The gnomon consists of two parallel plates each with a figure-8 analemma cut out. When the figure-8 apertures are rotated toward the sun, the dial illumination is corrected for the equation of time by reading the correct edge of the analemma for the date. If it the gnomon is turned sideways to the sun, the gap between the plates form a slit that produces a narrow beam for reading solar time adjusted to the longitude of the Pacific time zone. The hour scale is marked out at 5 minute intervals. Hours are labeled for Standard Time and for Daylight Saving Time.
 
 
Dawson Creek British Columbia Canada Analemmatic Dial Dial 929
An analemmatic dial 23 feet 7 inches wide consisting of a simple concrete slab with black painted marking. Shows solar time plus one hour (akin to Daylight Saving Time). Dial is in memory of a local artist and community activist Edna McPhail (1923 - 2008) who championed the development of the Peace Park in which the dial is located.
 
 
Brentwood Bay British Columbia Canada Horizontal Dial Dial 928
This is simple horizontal sundial with the standard cast bronze dial plate, 12 inches in diameter. The sundial shows local solar time with Roman numerals from V to VII with noon marked as XII. The dial is delineated with marks for the half and quarter hours. The hour lines and gnomon angle are correct for the latitude. The gnomon root is in the center of the circular casting. Radiating out from the center is a compass rose showing the cardinal directions.
 
 
Vancouver British Columbia Canada Analemmatic Dial Dial 927
The analemmatic sundial is laid within a 15-foot circle of light red concrete, set in the middle of a large grey concrete concourse on the south side of the school. Hour points are marked by 4-inch bronze disks embedded in the concrete; the declination scale is made of embedded tiles. The scale is red in part and blue in part, denoting the summer and winter periods. Correspondingly, each hour point hour is labeled twice; red for Daylight Saving Time and in blue for Standard Time. The dial incorporates a longitude correction for the time zone, and features Sunrise & Sunset Markers ("Bailey Points"). All labels were hand-painted by students - a deliberate measure intended to require occasional repainting and hence continued student engagement and involvement with the dial over the years.
