Milwaukee Wisconsin USA Analemmatic Dial Dial 1000
During the design of the bridge across the lagoon, the walkway was extended in the center on the north side, creating a niche for a 12 x 6 foot analemmatic dial. The dial is painted bright yellow with hours marked from 5am to 9pm (daylight saving time). The 1pm hour mark is set 8 1/2 minutes past local noon corresponding to its location just east of the Central Time Zone meridian. The walkway is marked with a central line using tic marks for each month and solstices. As of 2019, the paint is well worn. The dial has red circular Bailey marks for observing the direction of sunrise and sunset. Latitude and longitude are painted on the dial as well. At the north side of the dial on bridge railing is a sign explaining how to stand on the dial and use the equation of time chart to get civil time
 
 
Anchorage Alaska USA Sculpture/Artwork Dial 999
A sun sculpture called "Solar Path". The large 24 x 35 x 12 feet sculpture made by renowned artist Bill FitzGibbons consists of a blue vertical pole and two low sloping wedges. The vertical column makes a linear shadow that is supposed to show approximate solar time as it passes over evenly spaced inlaid hourly numbers from 8am to 8pm. This is not a functional sundial! The short wedge points to where the sunrises on the summer solstice and the longer wedge form points to where the sunrises on the winter solstice.
 
 
Fairbanks Alaska USA Equatorial Dial Dial 998
This equatorial sundial uses the shaft hole of an old airplane propeller as a nodus to cast a sun beam spot on the equatorial band. The arms are made from pieces cut from an unused pipe section intended for an oil pipeline. The dial appears to have time zone compensation. The hour marks are labelled for both Standard and Daylight Saving Time (with no minor marks). The propeller hole shines light onto the words "summer", "equinox", and "winter".
 
 
Port Hueneme California USA Horizontal Dial Dial 997
A large, 20 ft. diameter horizontal bronze dial constructed in memory of Alaska Airlines Flight 261, which crashed 14 miles offshore nearby on January 31, 2000, with the loss of all aboard. 88 bronze plaques surround the dial on its beveled edge honoring passengers and crew who died. The dial face is simple without hour lines but Roman numerals from 8am to 4pm to mark the hours. The thin, gleaming gnomon is decorated with dolphins at the base symbolizing the sea into which the plane fell. The sundial is set in a circular plaza 36 feet in diameter.
 
 
South Hadley Massachusetts USA Vertical Dial Dial 996
This vertical sundial declines slightly to the southwest in alignment with the building wall. The 1x1 meter dial is of concrete and built in the middle of the south wall. Because of its size and height at least 25 feet above ground, it was made to be seen at a distance. In 1916 when it was built, the land to the south was clear and many early photographs show the dial prominently on the south face One hundred years later many trees block the sunlight to this fine sundial. The dial is delineated in half-hour lines spanning from the 7:30am line in morning to the 6pm hour line in the evening. The hour lines are marked with Roman numerals. There are no solstice or equinox lines.
 
 
South Hadley Massachusetts USA Vertical Dial Dial 995
This vertical dial is a quaint and simple sundial made of wood. It is nearly square in shape with hour lines radiating from the gnomon. The hours are marked at the edge of the square in small Roman numerals. There are no solstice or equinox lines. The black disk on the dial face is the base of the gnomon.
 
 
Richmond Virginia USA Horizontal Dial Dial 994
A large circular plaza holds 7 life sized bronze statues of influential Virginia women during the last 400 years. The plaza will eventually feature 5 more life-size bronze statues. Dedicated in Oct 2019 this monument is a work in progress with other women still to be recognized. In the center of the plaza on a wide circular granite pedestal is a bronze horizontal sundial. In addition to the normal dial furniture of compass rose, inscriptions, site latitude & longitude, and a chapter ring with the hours from 5am to 7pm there is additional information: points of interest in Virginia shown around the dial in the outer chapter ring. Each location is listed by name, azimuth, and distance from the Capitol site. Underneath the style of the gnomon is a bronze Northern Cardinal, the state bird of Virginia.
 
 
Cincinnati Ohio USA Analemmatic Dial Dial 993
This analemmatic sundial is laid out in brick. The walkway consists of an inlaid brass analemma surrounded by month indicators for where to stand etched in brick. The analemmatic ellipse is brass, etched with time marks every 15 minutes. Just to the inside and outside of the ellipse are the hours in standard and daylight savings time. Brass indicators are inlaid for the Bailey Points to show the of time and direction of sunrise and sunset. At the edge of the circular brick plaza are granite markers of the cardinal points.
 
 
Breaux Bridge Louisiana USA Equatorial Dial Dial 992
This is a simple but well designed equatorial dial made of a steel frame and 4-foot diameter aluminum equatorial band. This time band can be loosened from its frame and rotated to an equation of time offset position that's based on solar noon according to dates on a placard fixed to the base. When adjusted, the dial shows time to within a minute. The 10-minute time marks and Arabic hour numbers used vinyl numbers and strips as cover during sand-blasting of the aluminum time band. The vinyl was removed leaving the reflective and polished marks and numbers against the grainy sanded aluminum. (This process was first done on a test piece five years earlier and placed it in direct sunlight - no signs of deterioration or coloring. So this is a relatively easy and permanent alternative to chemical etching). Attention is given to alignment with the base adjusted in azimuth and the dial adjusted with a set of three-point latitude and skew alignment bolts. This dial is an excellent study in functional design. According to the builder, "It was a real fun project. Getting it designed and properly setup was challenging. It has given me a keen appreciation for what it must have taken to build some of the great dials around the world!"
 
 
Nanaimo British Columbia Canada Horizontal Dial Dial 991
This is a beautiful but standard mass-produced dial, with chapter rings for Roman numerals, hour lines, half and quarter hour lines. In the center is the sun surrounded by a compass rose, The dial is brass and sits on a tapered square pillar of cut stone. The gnomon is a solid, unadorned shape. Pictorial evidence from the Internet suggests that the dial has been vandalized and repaired more than once.
 
 
Vancouver British Columbia Canada Sculpture/Artwork Dial 990
This artwork along Prince Edward street stretches about 1.5 mile (2.4 km). The latitude and longitude are given for the mid point. As public art the installation is know as Solar Patterns I and II. They are a collection of metal banners attached high on street poles and at eye level, an explanation of the pattern in the banner. Each banner consists of a yellow or orange aluminum sheet perforated with round holes representing the sun following a simple curve that is part of the analemma. The third dot from the top of the banner is replaced by an image of the sun as conceived by various artists ranging from school children to iconic images from various cultures to historic representations of the sun from cave paintings.
 
 
Lake Cowichan British Columbia Canada Horizontal Dial Dial 989
This is a beautiful but standard mass-produced dial, with chapter rings for Roman numerals, hour lines, half and quarter hour lines. In the center is the sun surrounded by a compass rose, The dial itself is brass, but sits on a round cast iron base all sitting on a square concrete pillar. The gnomon was vandalized and now is missing. The base is losing its protective coat of paint and starting to rust. A thick hedge has grown up around the sundial, obscuring the sun on the east, south and west sides. It appears to be largely ignored.
 
 
Fort Wayne Indiana USA Horizontal Dial Dial 988
This is a large 20 foot diameter horizontal dial embedded in the cement sidewalk. Brass hour lines extend from the edge of the circular dial to the toe of the gnomon. The gnomon itself is a brass triangle, tarnished except for its tip that is frequently rubbed by visitors. Arabic numerals mark time by hours from 6 am to 6 pm.
 
 
Fort Wayne Indiana USA Horizontal Dial Dial 987
This horizontal dial is 16 inches square, made of limestone with a brass gnomon. The gnomon angle is 30 deg, certainly not correct for the dial's latitude of 41 deg. Nonetheless, it appears that the dial was made for its site as the gnomon and dial numbers are rotated on the square to point due north. Arabic numerals mark time by hours from 8 am to 6 pm, with raised hour lines extending toward the gnomon. The equation of time is shown as a graph on one side of the plinth. The limestone is deteriorating with age and is now covered with lichen. The 3 and 4 pm numbers are nearly obliterated and in several more years many of the other hour numbers will vanish. The dial is situated under trees with little opportunity to see the sun.
 
 
Fort Wayne Indiana USA Armillary Sphere Dial 986
This is a 32 inch diameter armillary dial made of painted steel. The gnomon is a classic arrow at a 41 deg angle. The equatorial band is painted black with bronze colored Roman numerals indicate the hours from 6 AM to 6 PM. The dial is mounted on a field stone plinth.
 
 
Houston Minnesota USA Analemmatic Dial Dial 985
A simple analemmatic dial laid out in a square concrete base. The walkway and hour surrounds are black with white lettering. The hours are Roman numerals run from VI (morning) to VIII (evening). The dial is adjusted for daylight saving time and longitude such that when the sun is on the meridian, the dial shows about 6m after 1pm.
 
 
Webster Groves Missouri USA Armillary Sphere Dial 984
The armillary sphere has three rings: (1) an equatorial time ring made of brass formed into an incomplete circular arc with a 36 inch inner diameter, a thickness of 1/2 inch, and width of 3 inches. Time markings in 15 minute intervals are inscribed on its inner surface with Arabic hour numbers; (2)a meridian ring made of steel formed into a circular arc 37 inches diameter, a thickness of 1/2 inch, and a width of 3 inches; and (3) a horizon ring made of steel into a circular arc 38 inches in diameter, with a thickness of 1/4 inch, and a width of 2 inches. The sundial is supported on a steel pedestal having an open square frustum construction. The gnomon is a steel rod having a pointed arrow tip aimed towards the North Celestial Pole.
 
 
St. Louis Missouri USA Vertical Dial Dial 983
The Mullanphy School is the last school of 48 designed by and constructed under the guidance of William B. Ittner (1864-1936), an architect and Commissioner of School Buildings for St. Louis, MO. Only hour lines are marked on this simple vertical sundial. The picture of the sundial was taken at 1:41 PM CDT on 7 May 2019. Using the relation T(solar) = T(civil) + EOT - Daylight - LonCorrection, with EOT=3.3m, Daylight=1h, and LonCorrection=1m, indicates that the dial should show 12:43:31. This suggests that Ittner’s sundial at the Mullanphy School displays this sundial time to a reasonable approximation, especially considering that its only time markings are hour lines.
 
 
Logan Ohio USA Analemmatic Dial Dial 982
An analemmatic dial set in a gravel rectangle. It has a concrete walkway and circular hour markers in two ellipses for standard and daylight time. The hour numbers are adjusted for longitude, shifting them by 30 minutes (such that the due north line reads 12:30).
 
 
Magdalena New Mexico USA Obelisk or Vertical Gnomon Dial 981
This vertical gnomon sundial sitting on a 46-by-35-foot concrete slab was constructed using concrete piers of a solar mapping radio telescope array that Robert Bracewell originally built near the Stanford University campus. The array was abandon in the 1980's. The 10 piers were moved to the VLA in 2013 and arranged as a vertical gnomonic dial. NASA: "As for most sundials the shadow cast by the central gnomon follows markers that show the solar time of day, along with solstices and equinoxes. But markers on the [Bracewell] radio sundial are also laid out according to local sidereal time. They show the position of the invisible radio shadows of three bright radio sources in Earth's sky, supernova remnant Cassiopeia A, active galaxy Cygnus A, and active galaxy Centaurus A."
