The small horizontal band is 0.5 inches wide. The arrow is 29.5 inches long. It points in a westerly direction, meaning the dial is decorative but not useful for telling time.
Tucson Arizona USA Sun Alignment Dial 1039
The Vista Sun Wheel is 63 feet [19.2 m] outside diameter and 197 feet [60 m] in circumference. The Wheel is composed of 28 tons of broken limestone. The central cairn is 11 feet [3.4 m] in diameter and 3 feet [1 m] high. In the center is a post marked by a sandstone block about 30 inches [76 cm] tall. The floor of the Sun Wheel called for another 28 ton of crushed decomposed red granite about 3/4 inch [2 cm] thick. Stone spokes indicate the solstices and equinox. Other stones 30-40 inches [75-100 cm] are set to various alignments outside the ring. A post indicates the setting sun on Groundhog Day, indicating one of the cross quarter days. The layout was made by direct observation, watching the progress of the sun along the horizon to solar standstill then return. 18 months were required to observe, mark and verify positions then setting stone and making the ring. The layout is similar to the Bighorn Wheel in Wyoming.
Louisville Kentucky USA Horizontal Dial Dial 1038
This 11-inch (28cm) octagonal bronze horizontal dial uses arrowheads as a subtle design element. The 14 hour lines are represented as long arrows aimed at the base of the gnomon and are delineated to quarter hours. . The hours are marked in Roman numerals, but only from 6AM to 6PM. There are three curved lines of unequal length that partially encircle the dial indicating the amount of daylight in the and each one ends with a pointed tip. The marker for Noon resembles the Roman symbol for Mars, with its arrowhead pointing straight up. A winged hourglass graces the southern portion of the dial face.
Mountain View California USA Analemmatic Dial Dial 1037
Analemmatic sundial 16' x 10' (4.8m x 3m) painted as a full ellipse on the driveway to a house. Shows local solar time. Time corrections to obtain civil time (Equation of Time and longitude offset) are given for the first of each month on the Zodiac Walkway. Sunrise and Sunset sighting points (seasonal or "Bailey" points) are provided for a theoretical horizon, but are not useful as the dial site is within a valley. The perimeter of the ellipse is marked with great circle navigation directions for a selection of historical solar and celestial observatories, especially for North America, but all historically inhabited continents are represented. A QR code is provided for a link to a website with instructions for the dial, reference links on sundials (including NASS), and links for the selected observatories on the perimeter. The 2 degree slope of the driveway was not compensated for in the sundial layout, but the dial is unshaded from roughly 9:00 am to 5:00 pm in the summer.
Annapolis Maryland USA Noon Mark or Meridian Dial Dial 1036
This brass mariner's compass about 12 inches in diameter is mounted on the east side of a concrete pillar. It is known on campus as "The Ptolemy Stone". It functions as a meridian transit with altitude marks every half degree engraved on the upper south quadrant. The alidade has a notch on the upper end and a plate at the lower end, designed for measuring the altitude of the sun using the notch shadow (preventing eye damage of sighting the sun directly). The pillar is just over 3 feet tall with a sloped top. The main slope is that of the site latitude. A steeper "north face" is cut plane to the celestial equator. To make the equator "visible", a ring is mounted to the face. The ring casts no shadow on the equinox and from September to March is in shadow. A similar Ptolemy Stone is at St. John's campus in Santa Fe, NM.

Cañon City Colorado USA Horizontal Dial Dial 1028
This sundial was constructed on the top of a 10-foot round, 75-ton column of reinforced concrete used to anchor aerial tram cables spanning 2200 feet across the Royal Gorge. Construction started in January 1969. The column is tilted away from the cables, so the dial face is inclined about 5 degrees toward the south. Hour lines are labeled with Roman numerals from V to VIII, with 15-minute marks between. The original gnomon -- two steel angles welded together -- was melted and twisted and the painted face of the dial severely damaged by a large wildfire in 2013, which destroyed most of the park. The tram has now been replaced with a gondola ride which doesn't use this anchor. The sundial was restore in 2015 but since has deteriorated.

Sacremento California USA Equatorial Dial Dial 1024
A 6 foot wide x 5-foot high burnished stainless steel equatorial sundial. The meridian arc is parabolic shaped and the equatorial arc is slightly more than a gracefully tapered half-circle 5 1/2-feet in diameter. The central elliptical gnomon plate, which swivels to face the sun, has an analemma cutout that casts an accurate civil-time shadow onto the equatorial ring below. The gnomon plate is laser-etched with the analemma, months and 365 days of the year, and marks for the equinoxes and solstices, and instructions. The equatorial timeline is laser-etched with hour and minute marks from 6:30 AM to 6:30 PM. The sundial body rotates and locks in position for either Daylight Saving or Standard Time. The sundial is highly accurate compensating for longitude (the equatorial ring is rotated 5min 24 sec early to measure solar time on the pacific meridian) and equation of time (by reading the east or west edge of the analemma plate gnomon shadow). The sundial often indicates clock time to within seconds and the date to within a portion of the day. A stainless steel base cover encloses the mounting hardware beneath.
Bala Cynwyd Pennsylvania USA Vertical Dial Dial 1023

Indianapolis Indiana USA Horizontal Dial Dial 1006
Nestled among the trees in a small triangular park is a monumental horizontal sundial with oversized hour marks. The apparent method of reading the Roman hours that are all south of the 6am - 6pm line, is to look at the shadow then gaze across the sundial to read (upside down) the hour. The hours are 6, 9 ,12, 3, and 6. On the north side of the 6am-6pm line are 3 plaques where the normal 9, 12, and 3 hours should be. One is a plaque for Robert McCord who planted and maintained the park during the 60's until his death. Another plaque records that the McCord Park sundial is dedicated to a local police officer, William Whitfield, who was the first African American police officer killed in the line of duty in Indianapolis. His name is engraved on the central part of the large triangular sundial gnomon. Surrounding the base of the sundial are ceramic tiles from Barbara Zech, a local clay artist who fired the tiles created by students from the nearby school. The tiles have the theme of "home" and "community". The park renovations were headed by the group Keep Indianapolis Beautiful.
Marshfield Massachusetts USA Analemmatic Dial Dial 1005
This beautiful and educational analemmatic sundial is painted on the blue background of a 14x10 foot concrete pad. The ellipse itself has a semi-major axis of 76 inches and a semi-minor axis of 48 inches, particular suited for children. The zodiac walkway is nicely painted in white with clean stenciling of the months. The solstices and equinoxes are marked in large letters and the cardinal points are flagged in red. [Note: a number of vendors will make paper or plastic stencils that with a stiff brush create impressive lettering.] The hour marks are bright yellow suns enumerated in standard time and offset for longitude. The paint is covered with a clear sealer (Duromar DF-5610 “Solventless, Zero VOC, UV Stable Clear Polyaspartic Topcoat”) plus a bit of "shark grit" (Duromar DuroTrac "Invisible Traction Grit") to roughen the surface a bit to give some traction. This is similar to the approach taken by John Carmichael for the dial he designed at the University of Arizona, NASS Registry #825.
Longport New Jersey USA Sun Alignment Dial 1004
This concrete and bronze dial is really an alignment sculpture, honoring events from Armistice Day (Nov 11, 1918) to Pearl Harbor (Dec 7, 1941). A five-vaned support casts a shadow onto brass medallions on the time and date of the event such as the 11th hour of the 11th day of the 11th month for Armistice (Veterans) Day. Surrounding the dial are five bronze plaques representing the different branches of the U.S. armed forces.
Norwell Massachusetts USA Vertical Dial Dial 1003
This vertical declining dial is made of painted plywood with a simple white background and black hour lines and Arabic numerals. The gnomon is a brass rod without nodus. The hour lines have been adjusted for the difference between the site's longitude and the 75° W standard-time meridian. The hours are numbered as Eastern Daylight Time (EDT) instead of Standard Time, because in winter the sun is mostly low in the sky and trees in this wooded area block sunlight from reaching the sundial. Of course to obtain correct EDT, the equation of time needs to be added to the dial's time to account for the variable meridian passage of the sun. At most this amounts to -14 minutes (mid-February) or +16 minutes (early November).
Black Rock City Nevada USA Equatorial Dial Dial 1002
"About Time" was a 30 foot long, 3000 pound wooden pyramid. This installation projected time using two sundials: a gnomonic vertical sundial that swept its shadow of time out across the desert floor and an equatorial dial located on one faces of the pyramid. A platform at the peak of the pyramid allowed observers to become the gnomonic sundial’s apex and to experience 360 deg views of the landscape. At the end of the installation the piece was burned, a testament to the unidirectional march of entropy and time, underscoring the fleeting nature of the present moment.
Mexico City México Mexico Vertical Dial Dial 1001
This is a south facing reclining vertical sundial made of stone about one and a half meter square. The dial's concrete mount adjusts the dial to true south even though the carillon tower is not N-S aligned. Hour lines and Roman numbers on the dial go from 7am to 5pm. Monthly declination lines show the date as well as the solstices and equinox. A simple rod gnomon exits a gold ball at the top of the dial. The dial itself is well above eye level and hard to read. The other end of the carillon tower has an Aztec calendar.
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
