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
The Sun Shell is a band shell made of a series of six stainless steel arcs creating the illusion of longitude lines on a globe tilted so the poles are on the east-west horizon. A nodus is placed on one of the arcs that casts a point of light onto the floor of the band shell plaza. The floor is marked with Arabic numerals and stainless steel hour lines from 10 am to 3 pm.
Denver Colorado USA Vertical Dial Dial 962
A massive vertical dial, declining 48.08 degrees south of east, occupying the upper portion of the Arraj US Courthouse. Hours are marked from 5 am to 3 pm with Arabic numerals. The hour lines are crossed by declination lines for summer solstice, equinox, and winter solstice.
Owasso Oklahoma USA Analemmatic Dial Dial 961
This is a nicely done 12 x 6 foot analemmatic. The time ellipse is white concrete with black hour marks using Roman numerals. Time is adjusted for longitude and daylight savings time. The walkway has black month marks and an explanation plaque.
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. The gnomon deviates from the classic arrow, having a gold flange at the base and a spiked orb at the north end.
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.
